Computer Maintenance and Training Manual assignment help sydney Finance online class help

In this manual you will learn how to maintain your pc as well as learn about the safety while doing so. There are so many things out there that people do not know about computers that you will be shocked about in this manual. Maintaining the hardware in your computer will keep your computer running for years. It will also be cheaper for you over buying a brand new computer. On the next page you will find a diagram of your tower. This will help you be more familiar with what you are working with on your computer. So let’s get to learning about knowing how to maintain your computer.

Diagram 2 Safety and Environmental Concerns 3 Safety I will be telling you how to clean a pc that has dust inside it and around it and how to deal with heat issues as well. There are some things you need to know before working on your computer as well as equipment you need to have handy. Some things you need to have with you to keep yourself from being burned or electrocuted are ground bracelet (also known as a antistatic wrist strap), ground mats, static shielding bags (to put old components in), and antistatic gloves.

These items are for your safety while working on your tower. Never forget to turn off your tower and unplug it before working on it. Cleaning How often do you clean your computer case, inside and out? Did you realize that having a clean computer is a necessity for the system to run at its optimal levels? Having dust and dirt build up inside your computer case can restrict the airflow and cause serious damage to your components. One common example is when dust gathers on the heat sink and fan. If left there it can eventually cause the processor to overheat and shutdown the computer without warning.

The main factor to consider when you clean inside your computer case is safety. You will first need to be familiar with how to open computer cases and the precautions you have to take. There are important steps to complete before starting to clean your system like removing all plugs from the computer and certain preparation to make sure you do not damage the components inside your computer case. Of course it is preferred that you have the professional tools to clean inside your computer case, however you do not always need all the fancy cleaning tools available.

Everyday household items will do. Here is a list of some of the tools I use to clean my computer. * Soft paint brush: I use this when an air compressor is not available. Gently brush the dust from inside the case. Make sure you do not accidentally move any wires or connections. * Air compressor: I would choose to use this before anything. It’s quick and easy and removes dust properly. Do not go too close to the motherboard though. It will work fine from a distance. It is also best to remove the cpu fan and clean that separately. Compressed air can: When you clean inside your computer case, this disposable compressed air can that will blow the dust out. Be sure to keep the can upright, otherwise it will leak liquid. Always read the instructions on the can. (Pictured left. ) * Vacuum: Some people use this to suck the dust from inside their computer case, however a normal household one will not do. It is best to use a battery operated, handheld vacuum specifically designed for this purpose. Household vacuums cause static electricity which can damage your computer components.

Safety and Environmental Concerns 4 * Dust Mask: This is great for those really dusty old computers. I don’t think it would be very healthy to breathe it all in. Unauthorized Software Installation Installing unauthorized software programs (such as games to play during break time, signature files for email, weather programs, etc. ) on your computer at work may seem harmless or even beneficial (as with applications that make your job duties easier). However, software from unauthorized sources can create many problems. For example: ?

Freeware and low-cost software downloaded from the Internet or distributed on floppy disks or CDs can contain viruses that will infect your system and spread to other computers on the network. ?Unauthorized software may be poorly written, intended for use with a different operating system, or have conflicts with currently installed software that can cause it to crash your computer or send unwanted messages on the network. ?Unauthorized software might be pirated (copied illegally), which could subject the University to penalties in case of a software audit. Unauthorized software may contain spyware that will capture information you type and send it to marketers or criminals. ?Unauthorized software, once installed is seldom kept current. The software may not contain known security flaws when installed but hackers may discover and exploit flaws. The software company corrects these security flaws and releases an updated version. Most users never update the software once it is installed and is vulnerable to the security flaws. As you can see, downloading unauthorized software can be anything but harmless. Please use caution and think twice before downloading.

Environmental Concerns There are so many things that are harmful inside a computer. In this section I am going to tell you how to deal with those things and how to protect yourself and others along with our environment. Computers are part of the world’s largest growing ewaste. People will throw away computers without even knowing what they are throwing into the trash. There are so many types of chemicals put into computers that are very harmful to people along with the environment. The composition of e-waste is very diverse and differs in products across different categories.

It Safety and Environmental Concerns 5 contains more than a 1000 different substances, which fall under “hazardous” and “non- hazardous” categories. Broadly, it consists of ferrous and non-ferrous metals, plastics, glass, wood and plywood, circuit boards, concrete and ceramics, rubber and other items. Some of these things are copper, aluminum, silver, iron, steel, gold, platinum, and palladium. Silicosis, cuts from CRT glass, inhalation or contact with phosphor containing cadmium or other metals. Tin and lead inhalation, possible brominated dioxin, beryllium, cadmium, and mercury inhalation.

These are just some things that are harmful to you or could happen if not handled or recycled properly. That is why it is important to dispose of computers properly. Cleaning the exterior and components * Water: Use water sparingly. It should only be used to slightly dampen your cloth. You do not want water dripping all over your computer. * Rubbing alcohol: I always choose to use this before water as it evaporates fast. It is also great for cleaning dirt and oily marks from the inside the computer case, mouse and keyboard. Cloth: (lint free) You should use a cloth to clean the exterior of the case, the mouse, cords, and keyboard. Only slightly damp. Fold your cloth over a few times to get in between the keys on the keyboard. * Vacuum: You can use a vacuum cleaner to extract dust and food crumbs from your keyboard. Do not use it to clean inside your computer case as it may damage your components. * Cotton Wool or Swabs: Also good for reaching those hard to reach places. * Car dash oil: This is great for blending in scratches on monitors and sometimes cases, like a Dell GX270 desktop.

Don’t use too much, as you do not want it dripping into the monitor air vents. * Eucalyptus oil: I use this to remove permanent pen from monitors or cases. Just put some on a cloth and rub on the writing and it will start to dissolve. * Cleaning your inside your computer case regularly, can prolong its working life. We could all do with less computer troubles and this is an easy task for most people. Removing things like dust, smoke residue, dirt, or pet hair can leave your system to breathe freely. Internal hardware installation 6 Motherboard Replacement

With replacing your motherboard you must know a few things before doing it. Some of these things are as follows: Why are you changing it? What form factor is your mother board? Does it fit your case? Are you looking for a gaming pc with more power or just something to check email and sites? Knowing these things will help you through the long run. Motherboards can be tricky without knowing these answers to those questions. You might just order a motherboard without even knowing what you’re doing and end up buying the wrong one as I have done myself. That’s why these things are so important.

There are many different types of form factors you have the ATX, MicroATX, FlexATX, BTX, and many more just to name a few. ATX and BTX are more for servers and gaming pcs. As for the others they are more for your regular use of the computer like checking emails or just chatting with friends. Next thing to know would be your power supply. Does it fit your case with the motherboard? Does it give your pc enough voltage? Is it compatible with your motherboard such as the pin is it a 24 pin or a 20 pin connector? You will need to know these things in order to keep your pc running.

With ATX and BTX you will need at least an 800 watt PSU. If your computer doesn’t get the voltage or watts it needs it will become useless. Next you will need to know what type of connector your optical drive and your hard drive uses. Do they connect with IDE connectors? Does it use the SATA connector? Many newer motherboards have only one IDE port (which supports two drives), whereas older boards have two. If you have more than two IDE drives, be sure your new board has a second IDE connector. Next we will need to know what kind of processor, RAM, and graphics card you are going or are using.

The processor is very important so knowing what type you will need for your new motherboard is important. With processors you need to know if they are compatible with the motherboard you have. Some manufactures will put what type of processor you will need to use with your motherboard. Ram is also important because it is your memory. You need to know if your ram fits in its slots and the case. Also you must know if your motherboard is using DDR3 or DDR2 memory. Without this you won’t be able to use your motherboard or pc. Without knowing which one your graphics card might not work properly.

With Graphics cards you must know if your motherboard supports it as well you must know if it is compatible with your processor. Next we move onto removing the cables connected to your motherboard. It is good to use either sticky notes or even taking a photo of your PC before removing everything. Knowing exactly where everything goes can be confusing. So if you know you don’t have a good memory or you get frustrated easily try to make it easier for yourself by using one of these steps for your memory. Internal hardware installation 7

Next we will be talking about switching out your motherboard. It is better to put all your new components on your new motherboard before you place it in your tower. There will be some screws that will need to be taken off of your motherboard before removing it from your case. Remove the screws and place your old motherboard in an antistatic bag for proper disposal. Then replace your mother board and you should be ready to go after replacing the cables. You will also need to have a windows disc handy just in case you have to reload windows. Battery Replacement

When installing a battery you must know the form factor that you are using for your motherboard. Assuming we know the form factor we will say it is for an ATX form factor and we are building a gaming pc. So with knowing this we know we need to find out how much wattage we are going to be using. With today’s pc’s the components seem to take a lot of wattage to get the power we need. We will say we need about 1200 Watts for our pc. With our pc needing high end components for the gaming pc they take up a lot of wattage. Ok now we need to make sure it has good efficiency and has a good warranty.

Corsair has a nice line of power supplies and they are modular where you can take the cords from the power supply and hook them into the new one. I recommend you use those brands. Now we also must make sure that our power supply has the needed connectors for our pc. In order for our pc to work properly we must have everything it needs connected to the power supply. After we have made sure everything is connected properly we are good to go and ready to play some games. Processor Replacement Replacing a computer processor can be required if your current processor is having problems, or you just want to make your computer run faster.

Although it may sound like a daunting task replacing a processor can be simple to do as long as you take the proper precautions and follow a step-by-step approach. Power down the computer, and unplug it from the wall. Turn the switch on the power supply to the off position as well. Take off the side of the computer case, using your screwdriver to remove any screws that may be holding the side in place. Lay the computer flat on its side exposing the inside of the case. Put on your anti-static wristband and attach the metal clip on the end to a piece of metal on the inside of the computer case.

Remove the RAM, video cards, cables or any other parts that are in the way of the CPU, CPU fan, and/or CPU heat sink. Remove the screws holding the CPU fan and/or heat sink in place. With your fingers, gently pry up the lock bar located on one of the four sides of the CPU chip this holds the physical chip in place. Gently remove the processor from the motherboard being Internal hardware installation 8 careful not to break off any pins. Take your new processor and place it gently into the processor socket on the motherboard. Do not bend or break any pins on the processor.

Put the locking bar back into place. This will require some amount of force to perform. Clean the top of the processor gently with a microfiber cloth then place a dime-sized amount of heat sink paste on the top of the processor. Take the CPU fan and/or heat sink, and clean the bottom so that any residual heat sink paste from the old processor is gone. Reattach the CPU fan and/or heat sink to the processor. Replace all parts, wires or other devices you previously detached. Reattach the side of the computer case turn it upright plug it in and turn the switch on the power supply to the on position.

Memory Replacement Installing more memory is the cheapest upgrade for your computer. By increasing the amount of RAM you have in your system the greater the temporary storage for it to work with when running programs and applications. Especially when using software to edit large files such as digital photos and videos alongside simple tasks such as just loading your computer with more RAM Windows will load faster and allow you to open and close programs quicker so that you can truly multitask. Wearing an anti-static wristband which should be done whenever working with sensitive electrical equipment.

There are differences between types of memory, so it is wise to make sure you have the correct type before attempting to install it to avoid damaging your motherboard and/or RAM. First locate your RAM slots which are typically located near to the CPU. You may need to unplug a few power cables to give yourself enough room to work with, though make sure you remember what you have unplugged. Remove the RAM from its anti static bag and hold it by the edges. This will minimize contact with the working parts hence reduce the risk of static damaging the RAM. Line the RAM up with one of the slots on your motherboard.

Make sure you have the RAM the correct way otherwise it will not fit into the slot correctly. You should also note whether or not the RAM is dual channel, in which case you will need two identical sticks of RAM in adjacent slots to get the full effect. Refer to your motherboard manual if you are unsure of this. Begin to push down on the RAM module. In some cases, fairly significant pressure is required, so push down gently at first and increase the pressure until the RAM slides into the motherboard. Ensure that the white tab at either side is locked in the vertical position which will keep the RAM module secure.

Finally, replace any cables you removed and put the sides of the case back on. Boot up your machine and check that your new memory is accounted for by the RAM check at post. Internal hardware installation 9 Hard Drive Replacement One PC truth is unshakable: It’s impossible to have too much hard drive space. Digicam images, space-hog programs, and music files demand ever more storage. Fortunately, mammoth-capacity upgrades are inexpensive (many 250GB drives cost less than $100), and you can install one in less than 30 minutes, not including formatting time.

Here’s how to install a new internal drive as extra storage or as a new boot drive. Here, we installed Seagate’s Barracuda 7200. 10, a $124, 320GB Serial ATA (SATA) drive, inside a Dell Dimension 8400 running Windows XP Home Edition. First, back up your critical files (don’t forget your Outlook . PST archive) to optical discs, an external drive, or online storage. Then check whether a CD comes with the drive, providing drive-specific information and general upgrade assistance. It may also later help you copy the contents of one drive to another. Install this software first.

Then, power down your PC, unplug all cables, and open the case. Next, ground yourself by touching a metal portion of the chassis. Look inside—your first task is to determine where your new drive will go. Bays for internal drives are usually located below the wider, front-accessible bays that house CD or DVD drives. If you plan to replace your boot drive with the new drive and don’t have an empty bay, your upgrade will involve more steps than we can cover here. But if you’re replacing your boot drive and you have an empty bay, follow our steps for adding a second drive.

After formatting it, use Norton Ghost (or a similar program) to clone your boot drive’s contents to the new drive. Then, revisit steps 3 and 4 to direct your PC to boot from the new drive. We’ll be installing a SATA drive, but the process is similar for the other common drive type, IDE. SATA drives use a thin, seven-pin data cable; IDE drives use a 40-pin ribbon cable that’s usually gray. If you’re unsure which drive type your PC already has, check its documentation or label. Most PCs more than a year or two old employ IDE hard and optical drives, and don’t support SATA unless they have a SATA PCI card installed.

More-recent desktops may use (or just support) SATA drives but should support IDE, too. Tip: If you transfer Windows XP from one drive to another, you may have to reauthorize Windows. Most hard drive kits include a data cable (SATA or IDE, depending on the drive), a power adapter cable (with some SATA drives), and screws. If yours doesn’t include cables, you can purchase them separately. First, the data connection. If you’re installing a SATA drive as secondary storage, follow the data Internal hardware installation 10 able from your current drive (assuming its SATA, too) to the other end. See if an unused SATA port lies nearby on the motherboard or an interface card. If you can’t find one, consult your PC’s documentation. If you’re adding an IDE drive as a second drive, you may be able to connect it to the same data cable as your primary IDE drive, or along with an IDE optical drive. Look for a third, free connector in the middle of the cable that connects your currently installed IDE drive to the motherboard. Note that some older PCs use 40-conductor IDE cables, not the 80-conductor ones current drives require. Compare your kit cable to the one installed—the 80-conductor variety has much thinner wires. ) 80-conductor cables are backward-compatible (both types use the same 40-pin connector), so you can swap out a 40-conductor cable for your kit’s 80 if need be. (The “master” drive goes at the end—see step 3. ) Next, consider the power connection. Our SATA drive has a 15-pin SATA power connector. If you already have a SATA drive installed, follow its power cable (the wider of the two connectors) to see if an unused power-supply lead with the same connector is nearby.

If so, earmark that lead for your new drive. If it can’t reach the empty bay, see if any bundled adapters help. Some SATA drives also support familiar legacy Molex four-pin power connectors—you can use a Molex or SATA connector. If so, hunt for a free Molex-style lead. Still no match? Then you’ll need an adapter, such as a Molex-to-SATA adapter (some kits bundle one), or a Y-adapter that splits a lead in two. IDE drives are simpler: They always use Molex connectors. You just need a free Molex-style lead (or a Y-splitter). When installing SATA drives, jumper settings usually aren’t an issue.

That’s not true of IDE, where a jumper indicates whether a drive is a primary (“master”) or secondary (“slave”) drive. Check its documentation for the proper setting. If your PC has only one IDE hard drive, it’s probably set to “master. ” Assuming you chain another IDE drive off its cable, the new drive should be set to “slave. ” (You’ll later have to change the jumper to “master”—and attach the drive to the cable’s end—if you remove the original boot drive and make the new drive the boot drive. ) Another option: Set both IDE drives on an 80-conductor cable to the Cable Select (CSEL) jumper setting.

The PC will determine master/slave status according to the drives’ placement on the cable (“master” at the end, “slave” in the middle). Next, look at your current hard drive to see if mounting rails are attached to its sides. If so, screw a set onto the new drive (look inside the case for spares), then slide the drive into its bay. Internal hardware installation 11 Otherwise, screw it directly into the bay. Four screws are sufficient. Usually, the label side points up; mimic the boot drive.

Attach one end of the SATA data cable (which is keyed for correct insertion) to a SATA port on the motherboard or interface card, the other to the drive. IDE data cables, also keyed, usually have a red stripe that lines up with the “pin 1” marking on the drive. Next, plug the power-supply lead (keyed, too) that you scouted out in step 2 into the drive, including any necessary extender or adapter. Then close the case. Next, boot into your PC’s BIOS-setup utility to verify that it recognizes the new drive and positions it correctly in the drive hierarchy. (Check your PC’s startup screen to determine which key launches the utility. Once there, also check that “auto-detect” is selected for the drives, if an option. If the utility lets you select the boot order, give your intended boot drive priority over any other hard drive. This information may be under Boot Options, Boot Order, or Boot Sequence. Save changes and exit the utility. Your PC will reboot. Tip: Using a SATA PCI interface card? It may have its own BIOS to check. Our PC runs Windows XP, which lets you partition and format drives within Windows. Older Windows versions, such as 98 and Me, make you do this from DOS. With XP and 2000, though, use Windows’ Disk Management utility.

Click Start > Control Panel > Administrative Tools > Computer Management, and choose Disk Management from the tree at left. Your new drive should appear, with a black bar indicating it isn’t partitioned. Right-click the bar, and choose New Partition to launch the New Partition wizard. Click Next, and check that Primary Partition is selected; click Next again, to the Specify Partition Size screen (don’t change the partition size in the “Partition size in MB” field); and click Next to advance to another screen, on which “Assign the following drive letter” should be selected.

Click Next yet again (to the Format Partition screen), and ensure that “Format this partition with the following settings” is selected and that the “File system” drop-down reads “NTFS. ” Click Next a final time, hit Finish, and formatting begins. Formatting could take an hour or more, depending on drive capacity. But don’t be surprised if your formatted drive has less capacity than the package claims. A 320GB drive, for instance, formats to about 300GB. Drive manufacturers advertise preformatted size, but a portion of the drive is inaccessible.

I/O Devices 12 I/O Devices Display The display is how you see the output of the computer. The display is the external monitor on a desktop or the attached monitor on a laptop. Although displays used to be made with cathode-ray tubes (CRT), flat-screen panels have replaced that technology. Flat-screen liquid-crystal display (LCD) monitors are lighter and have better display quality than older CRT monitors. Your display will connect to your tower to make it work correctly. You should have three cords that lead from your display.

One should be your VGA, DVI, or HDMI cord setup. These cords should connect to your tower at a spot where you see the pin connector. The next one should be your audio cord. this should also connect to your audio connector port on the back of your tower. the next cord should be your power cord which will obviously connect to the socket in your wall or your ground outlet cord. Your display is a very important part of your pc because without your display you will not be able to see anything that you are doing. Having one of the top of the line LCD or even an LCD TV is amazing to have even if you are a gamer.

I always say bigger is better. I love to play a game on a big screen so I can see every angle of the game and know when something is coming for me. Printer A printer is a device that prints output to a page. Printers come in color or simply black and white. Inkjet and laser printers are the most common home devices. Most businesses have laser printers since the quality is better and the output is faster. Printers can be connected to the computer or networked using a print server. They can also be connected through the two cords on the back of the printer.

One of the cords is your power cord and the other will connect to a usb port in the back of the computer tower. Having a printer connected makes everything easier when you have assignments that need to be printed out. Having a printer set up on a network is also amazing to have because any computer on the network can print from that computer and there is no need for cords. Also you will want to make sure you have enough ink for your printer. If you are an avid printer like me you will run out of ink before you know it so it’s always good to be stocked up on ink. DVD or CD-ROM

A DVD or CD-ROM is a media device on which the user can write data and information. DVDs have replaced CD-ROMs since they hold more information than legacy discs. DVDs are normally used as storage backups to save documents and applications in case of a hard drive failure. They are also used to create installation discs for software development. DVD or I/O Devices 13 CD_ROM drives are installed by placing them inside your tower or by buying an external drive. The external drive connects through a usb port on your tower. You will be able to buy cd-r discs or dvd-r discs to record any information you want to save on your disc.

This is very important to do if you are upgrading your hard drive or getting a new computer because whatever information you need off the old computer you can save to one of the discs and use it to put on your new computer. Keyboard, Mouse and Monitor The three devices vital to any computer system are the keyboard, mouse and monitor. The keyboard and mouse allow for selecting programs and inputting information, such as text and numerical data. The monitor displays these actions on its screen, and allows the user easy manipulation and movement between options.

Gamers often use a specialized version of the keyboard and mouse, or a joystick programmable for repetitive movements and frequent actions. Scanner and Printer A scanner converts a hard copy of a file or photo into digital information that it then sends to the computer’s hard drive. Once saved on the hard drive, this information is available for review on the monitor, and can be manipulated or enhanced with editing programs. A printer does the reverse of a scanner, and prints a hard copy of digital computer data and files. * Make sure all input and output devices are plugged in correctly to your computer.

These devices will not work if they are not plugged in to the correct ports or if they are not completely plugged in. * Reboot your computer. Sometimes, a simple restart can help troubleshoot issues with your input/output devices. * Click the “Start” menu, and select “Run… ” Type “devmgmt. msc and press “Enter. ” This will launch your Device Manager. Scroll down the list and look for devices that have a yellow exclamation mark next to them. * Right-click the devices, and select “Update driver software. ” Follow the onscreen prompts to update the drivers. This will solve any issues that may be linked with outdated drivers for your devices. Right-click devices that still aren’t working and select “Disable. ” Wait for a few seconds. Right-click again, and select “Enable. ” DVD Drive and Video Card 14 Installing a DVD Drive When choosing a dvd/cd drive you will need to make sure it is compatible with your computer bays. It can measure anywhere from 3. 25- 5. 25. The measurements are very important for when you decide to upgrade your computer with more drives so make sure it leaves room for more drives for in the near future.

DVD/cd rom drives can be used to view information saved on a cd or even used to listen to music on a cd. You can also use them to store information. Now let’s get into replacing your drive. Turn off the computer and remove the power cord from the back. Unscrew the appropriate screws that hold the case cover on and open the case of your computer. Once you have done this, you will have access to the screws that hold the drives into the case. Locate your CD/DVD drive that you need to replace. Unplug the clip that feeds sound to the sound card and label it. Next, unscrew the four mounting screws that are in the side of the drive.

Then remove the power plug from the rear of the drive and disconnect the drive cable. Take note of which end the red wire connects to. It will be either towards the power connector or away from it. Remove the drive, examine the jumpers on the back of the drive and note what setting they indicate. The available settings are Slave, Master or Master Only. Take your new CD/DVD drive and set the jumpers on the back of the drive the same as the jumpers that you saw on the old drive. Reconnect the drive cable, making sure that you align the red wire with the pin 1 on the connector on the drive.

Most times this is the same one as on the old drive. Connect the power cable, slide the drive back into the drive bay and secure it with the four mounting screws. The final thing to do before closing the case is to plug in the sound cable that you unplugged. Close the case and secure the sides with the screws removed. Reconnect the power cable to the computer and restart the computer. Installing A Video Card Installing a new graphics card, also known as a video card, is a great way to boost your desktop computer’s speed and processing power when it comes to games and videos.

A video card takes over image processing for your CPU, allowing it to focus resources elsewhere. A new graphics card can make your video smoother and your images crisper for games and movies. Follow these steps for installing a new graphics card on your desktop computer. Choose a graphics card for your desktop computer. Check your user manual or look inside your computer to learn which type of expansion slot it uses. Your new graphics card should match the slot, or it won’t fit. Typically, the video graphics card or slot will be labeled PCI, AVG or PCIe.

Compare the video specifications for games and other programs with the specifications for the graphics cards you are considering. Use the recommended minimum on software system requirements as a guide for how much memory and processing speed your graphics card will DVD Drive and Video Card 15 need for games and video. Prepare your desktop computer. Unplug your monitor, mouse, keyboard and other devices from the desktop computer tower. Leave the tower plugged into the surge protector.

Lay the tower on its side and remove the cover. If possible, work on your desktop computer in a non-carpeted area to reduce static electricity. Find a free expansion slot for the graphics card. If this is the first time you have removed the cover, you will probably see several free slots. You may need to remove an exterior slot cover to make room for the card. This will expose the connection ports on the graphics card to the back of the desktop computer. Remove the graphics card from its packaging, holding the video card by its edges.

Never touch the sides of the video card or you may damage it with static electricity from your body. Press the graphics card gently but firmly into the expansion slot. If the graphics card requires an additional power supply, connect it now using the user manual provided with the card. Install drivers and software for the graphics card. Plug your monitor, keyboard and mouse into the desktop computer and turn it on. Your graphics card usually comes with a CD for installing this software. If it’s not included, you may need to download the software from the manufacturer’s website.
