Some readers have found that a locked-down BIOS means that even though the fans will spin up on a new graphics card, nothing will appear on the screen. Before you order anything, look inside your case to check whether your current PSU is capable of running a new graphics card.Remove the side panel and look at the ‘Total continuous power’ figure. If you're going for a top-end card, you may even need 650- or 700W.
Head to Control Panel, ‘Uninstall a program’, then find and uninstall your drivers.
You can also ‘uninstall’ the Display adapters hardware in Device Manager. Before you begin the installation you should ground yourself to discharge any static electricity.
To do this you simply touch a nearby radiator or a metal part of the case while it’s still plugged in.
If you’ve ever wanted to play games on your PC, but found that it struggled with the demands of animating large battlefields or the rapid 3D rendering of driving games, there’s a solution that’s cheaper than buying a dedicated rig or one of the next- generation consoles.
With much of the processing that games require now being handled by the graphics card, fitting one to your PC can have a potent effect on its gaming potential.
