My computer has problems with randomly booting and restarting. Sometimes after I wake up in the morning, the computer is running because it's turned itself on. Sometimes when I shut it down, 10 seconds later it will start itself up again. Lately, when I start it up, the computer will run to the point where it is loading windows, then it will restart. It does this sometimes as many as 3 or 4 times before it boots all the way, and sometimes it doesn't do it at all. It also restarts sometimes when I'm playing almost any type of games. It used to be a frequent problem when playing Quake 3, but has not occured lately. Just the other day it restarted while I was playing Total Annihilation, a Direct Draw game. I can't think of any other instances where it might restart.
