For about 3 months now, I've been getting a rainbow variety of small squares all over my screen, only when I play a game like BattleField 2, or Doom 3, I have a Radeon X800 XL (CPI Express) graphics card, my system:
Gateway GT5012
2.8 Ghz Dual Core Duron Processor(Intel)
1 Gig of RAM
Everything is standard, hold the mouse, keyboard, and graphics card.
I play World of Warcraft and rarely see it happen, although it does sometimes after patches. The squares go away if I restart, I was really looking forward to playing the Prey demo and this happens too, except with it, and sometimes with the other the squares were black and gameplay started getting choppy...help! I've heard it could be overheating, so I cleaned off the back of the PC, ick, ton of dog hair and dust, and it still happens when I play anything but WoW, a man can only play one game so long. Anything to do with a CD probably won't work, for some reason my top CD driver has screwed up, wont read disks, and a few weeks ago, stopped opening...yeah boy, computers not even a year old...
I tried doing the update drivers thing in the other topic I just read, no such luck, just asked me to put in the disk, which SOMEONE lost.
