I've had this problem for almost two weeks now. My computer games would usually crash to desktop, so I tried a bunch of things. In the end the only thing that helped was taking off the sides of the case and sticking a large fan right next to it. The crashing was much less frequent, but it still happened. It would take much longer, though, and it the crashes would reset the whole computer rather than crashing to desktop. As of yesterday, the computer locks up even when I'm just in Windows. Before, it was only during 3D games. It may sound like a simple overheating problem. But with cooler weather and nothing done to the computer to make it overheat, it seems like much more than that. I'm guessing my processor is fried or something (not that I'd really know). My computer locks up when my processor is about 150 F (65 C), and it only takes a matter of minutes to get that hot, even with 7 fans in the computer and a large one blowing right on the computer. It used to lock up when it was 190 F (85 or so Celsius - yeah, I know, that's hot as hell). If it matters, I have an Athlon XP 3000+, Radeon 9800, and a gig of ram. I know it's not a software problem (I've tried many different drivers, versions of DirectX, and I've even reformatted and reinstalled windows XP). It's definitely hardware. So, any suggestions as to what's going on, or what to try?
