Hi, I recently built a new PC with the following hardware: ABIT NF7, rev. 2 AMD Athlon XP 2800 2x256mb Crucial PC2700 ram MSI GeForce FX 5600, 128mb ram SBLive! soundcard on-board NIC WD "Special Edition" 80GB HDD SONY DVD drive AOPEN CD Burner 350W PSU, brand name ="Max" Win98 SE Debian Linux In both Windows and Linux, the system constantly will lock up. When this happens, I can still see whatever was on the screen, but no input from the keyboard or mouse is accepted, and any sound playing loops over and over like a broken record. Only way I can reboot is by reset button. The problem doesn't seem isolated to games, as it seems to occur randomly. For example, I could be playing Ghost Recon for an hour just fine, but then when I exit out to do something else, and then restart the game, the system hangs. It has also crashed sometimes just on a fresh boot up. Does this sound like an issue of not having a big enough power supply? The dealer I got it from says it's reliable, but maybe it doesn't have enough wattage? I've checked the CPU temp immediately after one of these crashes in the BIOS, and it doesn't seem too high. Or maybe it spikes somehow? I have updated my BIOS, and have recent drivers loaded. Thanks for your help!
