Yesterday, while I was talking to somebody on Skype, my computer froze. I couldn't move the mouse, or ACD. So I manually restarted. After doing so, about 15 minutes after it reached the desktop, it froze once more. I rebooted manually, but instead opened it in safe mode. I left it there for an hour without incident, so I restarted back into Windows. Get to the desktop, half an hour later I freeze once more. By this time, it's about 10:45, so I turn it off once more, thinking that my computer is just getting too hot. I leave it this way overnight, and when I wake up in the morning, I started it up so I could print out a school paper. For 15 minutes, it worked well. I left it idle so I could go brush my teeth and comb my hair for about 5 minutes. I come back so I could browse the forums, and once again, it's frozen. I shut it down, and left for school. I am posting this on the bus from my phone. I have run two full virus scans with Kaspersky. Any ideas?
