Someone please help me, my cpu will restart on the hour. If I turn it on at 1:15, it will restart at 2:15, and then once its back up and at my desktop at about 2:18, it will restart at 3:18. Its weird! It just restarts itself, at one point I saw a blue screen for 1/4 of a second. Does any one know what the problem is? It is very annoying and I dont know what to do. I can not pinpoint which drive its on, I have 3 of them, C - which was my old WIndows 98 os, D - which is my 20 gb, Widnwos 2000 PRofessional drive, which i use everyday as I no longer ever use Windows 98 even tho its still available to use. E drive is for storage mainly. What should I do, many people say to reformat it, but I dont know how to pinpoint it to a drive or what the exact problem is. Could it be a virus? Any virurses do this? I dont see any other symptom,s, just a restart. Please tell me what I should do. Thanks.
