PC Radomly restarting with no bluescreen (think it's PSU related)

Hello again,

Over the weekend my screen went black whilst I was browsing some photos and the PC restarted. After a reboot it started to do it again when I began launching Rome 2 Total War. I checked event viewer and it was Event ID 41, there was no bluescreen and there was no bluescreen dump in the Windows directory.

I had this once before a few months ago and it was down to the graphics card drivers. When it happened last time it did it exclusively whilst playing Total War and I fixed it by reverting to much older drivers, but now it is doing it whilst the PC is idle and whilst I am browsing the internet.

I tried various things, beginning with the idea that it was the GPU again. I tried numerous driver versions but it kept restarting, sometimes the computer would restart whilst installing the drivers and sometimes it would restart before it got to the login screen.

My rig is overclocked so I decided to load the default profile so see if it was something to do with the OC but it was still restarting.

I tried a different graphics card and it did it again, then strangely I wasn't able to get it to POST and BOOT with the spare GPU, I could hear the PSU trying to power it making a sort of 'power up' noise repeatedly but nothing. I then went back to my normal GPU and kept troubleshooting. I've seen hundreds of posts all over the web for this problem and the fixes are overwhelming because there are so many probable causes, some people had faulty motherboards, some people had faulty PSUs and some fixed it by disabling audio drivers and some by changing the power socket in the wall!

I began to think it was definitely driver related because I don't recall it restarting whilst in safe mode at any point. I thought maybe the PSU was overheating so I used Corsair Link to turn the PSU fan on at 100% and it was still restarting. I checked the temperatures of everything in Corsair Link a few times and they seemed to be fine.

Then this morning I turned the OC profile back on and when I was back on my BIOS landing page (where it shows all the temps and the voltages) I noticed that the 12V rail graphical bar kept going into red, it was fluctuating between and 10 and 11 and I think when it hit 11.8 the computer restarted again and went black. This rules out any driver issues because it has done it whilst in the BIOS.

I know next to nothing when it comes to PSUs and rails etc and have no idea what this means.

I have everything hooked up through Corsair Link but I never use it, I haven't updated Corsair Link since October 2015.

I can't see how the PSU can be faulty, it's a HX 750i exactly a year old. I saw one person on a forum say that that the multi rail mode randomly changed the output power and protection or something and he changed it back through Corsair Link, but I don't understand any of this.

My spec:

> AMD 6300 FX 6 Core overclocked to 4.4 GHz
> Asus M5A99X Evo R2 motherboard
> 16GB Corsair Vengeance 2133 MHz
> EVGA GTX 760 ACX
> Samsung 500 SSD
> 3 x Western Digital Velociraptors
> H100i Cooler
> Sound Blaster X FI Fatal1ty Titanium


I'd really appreciate some guidance and help. Thank you.

i have the AMD FX 6350. a similar thing happened to me. i underclocked my CPU a little and that fixed it. try a lower overclock it might be too much for you PSU/Mobo.
