ok it just happened again while i was watching a movie online. i highly doubt it overheats.
**UPDATE**
so i continued watching the movie after the restart, happened again. just freezes, the sound keeps going for another second or two and then restarts. anybody? please?
**UPDATE**
and again. i think i'm gonna keep watching on my laptop. if this helps, this happened before i've put the CPU in on the same OS. also, my mother board is GA-880GM-D2H
