This guide will show you how to replace your graphics card; it may seem difficult, but it is very, very easy to do. Please note that you will not have one if you have an integrated video card. To understand the version of the integrated video card, find information on the Internet; and one more thing: if you live in the UK visit aria.co.uk, which is a good software and components site.
Steps
Step 1. Static electricity can seriously damage components inside the computer
To avoid this, you must ensure that you are grounded when working inside the computer. One way to do this is to purchase an anti-static wrist strap, which you must wear at all times. The ESD wrist strap must be connected to ground. An alternative is to touch a large metal surface (such as a heat sink).
Step 2. Remove all drivers associated with the current video card
Assuming you are using Windows, this can be done using the Control Panel: directly in Add or Remove Programs (wording may differ depending on the version of Windows).
Step 3. Open the computer case
To get into the "Tower" system unit, you will have to remove the panel that is on the right side when looking at the unit from the back. Open this side of the computer case by removing the screws at the back of the chassis that hold it in place. Then just slide the panel out.
Step 4. Locate the old card on the motherboard
It is usually located in the lower left corner.
Step 5. Disconnect the card
Many powerful graphics cards require additional power, so they have an extra power connector plugged into them. If it is a case with a card, unplug it by pressing on the top of the small handle located on the plug and pulling it out.
Step 6. Remove the old card
The card may be screwed onto the case, so unscrew it. Also, most of the connectors on the motherboard (sockets) have a lock, which is a tiny knob on the graphics card slot. Turn the handle down and take out the video card. Not much effort should be required.
Step 7. Insert the new video card and, if possible, secure it in the case
This time, you don't have to worry about the lock.
Step 8. Connect your new video card
Again, some video cards require additional power. If your new card comes with a power connector, you need to plug it in. Just plug the plug into a power outlet.
