Hello there,
I'm having an odd issue: abruptly and with no warning, the power to my PC cuts out. This happens seemingly randomly, as it has happened when I was gaming and also when I was doing nothing more strenuous that browsing Facebook.
At first I thought it was a PSU issue, since after happening a few times at random intervals my computer stopped turning on and the PSU would make a continuous high pitched whining noise when I pressed the power button rather than causing the computer to post. However, after replacing that PSU with a brand new fancy Platinum-rated 850-watt PSU (my max draw is 500, but I wanted to make sure), it just happened again.
Now, the power quality in this room isn't spectacular, but I have my computer running through a voltage regulator, so I don't really think it's that - although the lights in the room do flicker a little bit when I start a stress test, strangely. Regardless, the indicator on the voltage regulator has shown that it's working properly and the power reaching my computer is constant and clean. So I don't really think it's that.
Additionally, I have HW Monitor Pro, and although there have been some temperature spikes - my water cooler is on the way out, and I need a new one - they haven't been quite up to auto-shutoff levels, and more than that, the spikes don't seem to coincide in the logs with the random shutoffs.
DxDiag file found here.
Anyone have any thoughts on what it could be?
