About a week ago, my HP DV5Z laptop began randomly freezing. I didn't change anything at all on it, no updates to drivers or the OS or anything. It's always while playing a game; I don't think it's ever happened outside of a game. For a fraction of a second, the screen will be shifted either up or down slightly and then its back to normal, but it'll be completely frozen. Sound stops, mouse won't respond, whatever game I'm running at the time will be frozen. I'm at a loss as to what this might be, I've tried everything I can think of including updating every driver that there was a newer version of, disabled things that didn't need to be running, keeping the temp as cool as possible. The hottest it's gotten is about 80 Celsius while pushing it as hard as possible, which doesn't seem too out of line to me, although pretty often it'll even freeze at around 70 Celsius.
