Problem - Overclock or PSU?  

post #1 of 2
Thread Starter 
Hi all,

Have an Ultra x2 550w PSU. It's been enough power for all of my components (and I don't have many though I do have a GTX 260 - but it's been running fine for two months even with an overclock on the latest games).

Also have an E2180 with a great overclock (relative to the chip) which you can see in my sig.

But a few weeks ago my comp'd be going along and then just shut off. My old surge protector w/ backup battery from 2001 squealed one night and lit up the red light that indicates some sort of power problem. I plugged my PSU into another strip and pushed the power and it'd start a fan halfway for .1 seconds and not come on. Un- and replugged all components and it turned on and worked fine. For 30 minutes. After that I'd have to unplug the PSU, replug it, and it'd power on and work for 1 or 10 or 30 min. without unplugging components or anything. Had all temp monitors up for everything and watched them closely and it wasn't a temp issue, even cooled the room down to make sure.

I finally went and pulled my E2180 down to 2.0 from 3.56 (at which it was prime95 stable for 24+ hours, at which it's been OC'ed at for 8 months solid) and it worked straight for a week. I put it back up at 3.4 and it worked straight for a week. Then I come in this morning and the computer's shut off again. Unplug the PSU, replug, and it got into windows and went down again. Unplug/replug, wouldn't come on at all, now I assume it won't unless I un- and replug components all over again (at work so can't mess with it).

So, did my PSU just mess up? Is my OC suddenly wildly unstable? Think my old power strip w/ battery could have killed my PSU, would it be risky to plug a new PSU up if it is the power strip?

I'd think remotely possibly it was too much of a power draw, but I didn't have to be doing anything power- or CPU-intensive for it to just shut off.
