After reinstalling Windows 7, video game graphics problems and BSOD?

Originally, my computer would have a problem where the keyboard would randomly stop working and when I restarted and tried to load the desktop it wouldn't load.

As a result, I reinstalled Windows 7 (didn't fresh install).

Since then, whenever I play a PC game such as APB Reloaded, I keep getting random shapes in all colors appearing on my screen while I try to move and the game lags horribly.

I've downloaded 3 different drivers since and with no luck.

After restarting again, my computer Blue Screened.

I have no clue what's the problem.

  1. Uhm. What do you mean by "didn't fresh install"? The random shapes and colors is called artifacting. It would be helpful to post the particular BSOD error too. What graphics card do you have, and what do you mean 3 different drivers?

    The first problem you described seems to indicate a RAM or HDD issue. The second problem seems like it could GPU or RAM related.
  2. You should do a clean install of Windows 7. If that is out of the question, try this. Run CCleaner and do the Clean and Registry both. You may have to run it more than once until it comesback clean.

    If that alone doesn't do it, unistall the graphic driver again, reboot, and run Driver Sweeper from Safe Mode. Have it remove any remnants of AMD, ATI, and Nvidia graphic drivers it finds. Reboot and install the latest driver for your card and O/S.
