Hey, I recently (last day) finished building my new computer. I'm not the smartest person when it comes to computer terminology, but I'm sure I put everything together right. When I installed Windows XP, everything went well. Then I booted my computer, and after a while, just froze. I rebooted, and again after a while, just froze. I have lasted a while on my computer without freezing but it really bothers me. A couple of times it froze but I received a message from my video card (ATI Radeon X800GTO), saying it has restarted my VPU then everything is fine until a while then freezes again and it doesn't automatically resets VPU. This must be some kind of problem with the video card, but really have no idea. Can you provide me some suggestion?
