No recent hardware or software changes, but after 10-15 minutes or so the computer freezes... Can't do anything. I restart and same thing happens. It usually restarts fine, but once it didn't read a hard drive, I took it out and same problem. A couple times it started and froze while loading, but most of the time it freezes 10-15 minutes in. Swapped processor and RAM, and still the same problem. I also can't get it to finish a virus scan. Does it sound like a virus, or could that be a video card, or motherboard problem?
Thanks,
