My father purchased a computer from ibuypower.com a few years ago. I'm messing around with it, and I find that it cannot do certain tasks without crashing to desktop, freezing, or simply restarting. Such tasks are playing a game, rendering or converting a video, etc etc. I can't even right click on something more than once without it freezing. Doom 3 lasts for about a minute before the screen goes completely bonkers. Call of Duty UO lasts for about 6 minutes, while Max Payne last about 4. All the drivers are updated, as well as Windows. He doesn't have any of the CDs that came with it. I found the email with a list of the computer's hardware and such.
