Hey guys,

I have began to think my power supply is failing.

Previously, under load, I was getting random BSOD's and now my pc has began to reboot randomly, without BSOD. Like it looses power and then boots up again. It happens while gaming and while stress testing using realbench.

First time stress testing with realbench, I ran while cpu was overclocked slightly. Rebooted randomly without BSOD within the first hour. The cpu in the past was overclocked much higher and was running fine. Second time I ran was with motherboard default settings. Rebooted randomly without BSOD between 5-6 hours.

Temps across the system are all fine. I have done a clean install of windows and run and passed memtest.

Strange thing is though, I've tested cpu using aida64 with a higher overclock than testing with realbench, and that lasted 6+ hours without a crash or reboot.

So my question is, is it most likely my power supply failing? If so, how can I be 100% sure it is? If not, what else could it be and how do I confirm the fault?

Cheers, Alex

If you have a known good PSU then you would swap that in and see if it acts the same.
or you can buy a PSU tester online

Memory would be the next thing to look at hardware wise.
working with one memory stick at a time in the first primary slot(near the cpu---or look it up in the motherboard manual) memtest with one full pass... if no errors after, then your good.

hard drive would be the next thing--- crystaldiskinfo/ hard disk sentinel

then graphics card.... reseat in in the case once. then deal with reinstalling the drivers or reverting to an older driver or downloading the driver from your motherboard site.

other then that your looking at other system drivers.

Intel driver tool can see if your chipset and other intel drivers...

you can go into your "event veiwer" and see if any of the errors you can google and give you a clue..... just be aware that many of those errors will take registry fixes which you don't want to make any mistakes with. if people comment that its not critical then ignore it. unless its heppning 100.s of times then you might want to track it down.
