PC keeps powering off after an hour of use

post #1 of 15
Thread Starter 
So ive had this Coolermaster silent pro 850W for a few months now. Today the computer just powered off. The motherboard LED was still on the whole time. I couldn't turn it back on til I flipped the PSU switch and waited about 10 seconds then it boots up fine. It just happened again so here I am trying to find answers. Is this the sign of a dying PSU?

Not necessarily.
I see your CPU is overclocked, have you stressed it for long enough? It could be on too low a voltage for the OC. I would first recommend testing it on prime 95 for an hour, or until your PC shuts down by itself.
Would also watch your temps to see what they are doing during said stress test.

I havent stressed my cpu to much but every time I have in the past when testing an overclock it would always blue screen first. This is just a straight shut down as if the power in the house went out. I updated the bios after the first shutdown so my overclock settings got reset. I just left it at default for now and I got a shutdown after that too.

Ok, so we can rule out the overclock.
Have you tested your ram?

I had the same issue weeks ago with my PC. My situation was I was on a HEAVY O.C. on my CPU, and my Video Card's. My PC did the same thing yours did. I had to replace the Power Supply with a new one. mad.gif

memtest86. You need to boot into it from start up, It then runs the test independent of windows.
Follow this.
Warning: It can take a very long time, so give it a night or so. In the mean time you can manually test your ram by booting with 1 stick at a time and seeing if that makes a difference.
Also, when you do eventually get back into windows, is there any message which pops up?

Did your power supply end up going dead or did you replace it before it got to that?
