My computer was doing the spontaneous reboot thing, then it just died. I replaced the power supply with the Antec dual rail 12V that you see in my signature, and everything seemed to be fine. When I was playing Madden 05 earlier this morning, the graphics started to go a little goofy and then the game just shut off, but the computer remained on. I then turned on HL2 to see what happened. After about five minutes the computer rebooted in its entirety. I got the whole "windows has recovered from a serious error" and the website that it took me to stated there was a stop error with a device driver(?) although it does not tell me which. The CPU temp stays between 30-35 degrees celsius when idle and goes up to 50 degrees celsius when doing high graphics stuff (numbers from ASUS Probe). I'm not overclocking the video card or the CPU. The power supply I just installed has a pretty slow fan, it only hits about 1200-1300 RPM max, goes down to 700-800 when sitting around idle. Maybe because it's a bigger fan, moves more air? The temperature of the CPU hasn't changed at all with this new PSU, so I don't believe it's overheating. I dont know how hot the video card gets. The voltages seem right on with ASUS Probe. I attached the minidumps because I'm at the end of my rope. I thought I had the problem licked with a new PSU, but that's not the case. Can someone peek at these minidumps and give me some advice?
