i have an old xp pro that i love...but its been freezing up on me at random times and really doesnt seem to have anything to do with what i am doing at the time..i have tried everything and all dead ends...it always restarts correctly after a hard shut down...enough said about that...is frustrating. yesterday i was messing with settings...i had my new monitor set to a low resolution as i like things big onscreen...i changed the setting to the highest res...and no more freeze ups.....an easy thing to try if you are having problems...hope it works for you.
