This is driving me so damn crazy! I checked the RAM, HD, Motherboard, Viruses. ALL GOOD\CLEAN! but it still freezes and restarts every time! No over heating problems, room temp is very good. I cannot complete any work I do on this PC. I attached the log files from system/application events. Not a long log file, cause I cleared from before and started new session yesterday so it wont be long for you to check. pc restarted like 7 mins ago, errors should be in the logfiles. please I need urgent help. EDIT: Im using Windows XP Professional.
