Defragment the computer. This helps the computer run smoother, helping to speed up games. Windows 7 has a built in defragmenting program. Click the "Start" button, and type in "Disk Defragmenter." Click "Disk Defragmenter" under "Programs." Select the computer's primary hard drive, which is the "C:" drive. Click "Defragment disk."
Close unnecessary programs that are running in the background. These programs split your resources, and some games require a lot of power to run. Closing these programs frees up some of your computer's processing capacity.
Add new hardware. If your computer does not have a video card, by adding one you can help take pressure off the computer when running a game. A sound card will do the same. Also, if you can increase the amount of RAM available, the computer will have more memory to run large programs such as high-end video games.
