PSU possibly going bad??

post #1 of 5
Thread Starter 
Hello guys I have a question about PSU's. I already know that a bad PSU can and will randomly restart a PC. But can is lock up a PC, no crash just a lockup and freeze while gaming. I was thinking maybe the new 8.12 ATI drivers, or maybe my OC, and hopefully not the PSU. I reset my VC OC back to stock and as for my system OC I left it the same and am right now running IBT. So can a PSU lock up a PC or just restart it?

I would think it would just restart it, but then again, maybe it could be not allowing power to a specific component and screwing with the computer.

Do what I do, go to best buy, buy a new psu, test it to find out whether it works or not, and then when you reach a verdict, take it back.

Might have to test it out to further diagnose the problem.

Use a dif PSU then see what happens.

I'd do that too, but there's something else you could try before. Get Speedfan, or any other monitoring utility, and monitor the +12V rails. Speedfan can make it in the form of a graph, that's why it's convenient. After starting Speedfan, start a game and play for a few minutes (3-5mn) and then exit. Look at the Speedfan's +12V graph, if if falls under 11.6V or if it giggles a lot it may be the PSU.

After this you can always try Joe's idea.

I thought software voltage monitoring wasn't accurate.
