When I play certain video games on my computer the screen goes crazy but the game is still running When I try restarting the game my comptuer freezes Could my spyware be causing these problems

Spyware and viruses may be to blame, but you're graphics card is probably the biggest problem. Make sure it is fully updated to the most modern software, make sure your computer has enough RAM, and make sure your computer is atleast somewhat up to date. If it's an old computer, you should buy a new one.
