Today, I uninstalled a bunch of useless programs. Nothing important, just some trial versions for different DVD burning programs, that sort of thing. I don't know if that's relevent, but it's the only thing remotely system-y that I changed, and the problem started pretty much right after I did that.
Anyway, my computer, as you might have guessed, restarting without any warning, at seemingly random intervals. One second I'm doing stuff, the next I'm watching the computer boot up. No warning, no error messages. It's happened three times, so far, waiting intervals of about 10 minutes and a little under an hour. What I'm doing at the time seems to have no effect on it, all three times I was doing completely different things.
After the second time, I went and stopped all non-essential processes in the task manager. Didn't seem to do anything, though the interval did increase from about 10-15 minutes up, to almost an hour, as I said. Maybe that means something? Probably not.
Aside from the aformentioned uninstalls, I haven't changed a gosh darned thing. I wasn't doing anything particularly strenuous on the machine, at the times of any of the reboots (just winamp and firefox, pretty much.)
Any suggestions? Gotta post before it goes again. I'm going to bed, don't want these cold restarts to damage the system at all.
