Random lockups, with no OC

post #1 of 5
Thread Starter 
For that last month or so I've had my computer OCed. I was getting random lock-ups. By random I mean that they occur anytime, during any program, at any load. So I thought it might be my OC, so I backed down to stock values and I still get them. I've run Prime95 for multiple hours, and memtest up to 200%, and they run fine. 3DMark06 also runs fine. None of my temps are high. In fact, I get more lockups when I'm not at 100% load, during simple things like using Internet Explorer, or Visual Studio.

Any ideas? None of the stability tests are doing a damn thing.

Have you checked your RAM with memtest? Crucial has been known recently to be putting out faulty RAM.

EDIT: Never mind. I see you used memtest. Might be your mobo then

Try loading your OS cd and go for a repair using the CD booting?
I had a friend with the same problem and he had to reinstall his operating system. Fixed everything.
BSOD's were what he was getting, and random restarts.

Any BSODs or just random reboots? If youve gotten some bsod post the message and we can help you from there. Might wanna consider a reformat. Maybe the oc corrupted the os

No reboots or BSOD, just freezes up.

Every now and then I get a hint it is about to freeze up. I'll be surfing the net and suddenly animations stop and I can't click anything but my cursor moves, and then usually within a couple of seconds the mouse cursor stops responding altogether.
