I have no clue what to or where to look with this.. I just installed XP a couple weeks ago (upgrade from ME) and ive had issues over the past 2 days with the computer freezing up. Total freeze up. I have no mouse usage, I cant cntrl-alt-del, I have nothing.. It happens at random times, today I was outside for an hour, I came back inside and it was frozen... I laid down for 2 hours today, came back and it was frozen... Ive shut off the screen saver and it still occurs.. I have over 380mb of RAM and according to samurize, I have 200+ free (thats almost everytime I look at the stats.. I dont know if something is mysteriously chomping up RAM while im away).. Guys, any ideas at all?
