So here's the deal. I'm using XP. My computer has started to turn off (and not reboot) randomly for the past couple of months. I can be doing anything from writing a paper. Watching something on Winamp and playing solitaire. Listening to music. There is no error message. I've run Norton scans, and I've even gone to PCpitstop.com and run tests there. I'm not sure what to do or what the problem could be. Oh and if I try to turn it on a few seconds after it's shut down, it starts to boot up, but just turns off again. I usually have to wait a few minutes or more in order to use the computer for longer periods of time.
