My computer's been crashing lately. It'll shut down and restart abruptly, and without warning. When it comes back on, there's often a Windows Error window. I tried reformatting, thinking it was some sorta software glitch, but it just happened again! What do you think is causing it? It'll crash without programs running, on start up, while watching a movie- it's random. Coudl it be the powersupply? I have an Antec 380W, that's close to two years old. It's powering a cd-r, dvd, 80gb HD, 6gb HD, fx5900, and an external HD is connected to the comp, but has its own power. That shouldnt stress the PS that much right? Or could it be my motherboard? It's a p4p800 that's also close to two years old. I dont see why it could be the mobo though. Prior to the crashes, I rarely shut down my computer and only seldomly rebooted. Please HELP!
