Desktop hard reboots on starting any game

[tehpwner]

Just as the title says. This started this morning/yesterday. Works fine on the desktop but the moment I start a game (like WoW, but I tried a different one like AC:Unity with the same result) it black screens and kicks me to the BIOS bootup (no blue screen, I tried toggling off auto restart for blue screen but still nothing). The only thing I can say I noticed is that my BIOS yesterday had been complaining about it restarting due to a detected power surge. The computer is attached directly to a UPS unit so I doubt the interference is coming from outside the loop.

I checked the system temperatures and nothing rises above ~50C even under load.

I have done a fresh re-install of windows (including drivers etc) and re-flashed my bios but the issue is still present.

Specs:

CPU: Intel i5-3570
Motherboard: P8Z77-V LX
RAM: 16gb (2x8gb)
GPU: EVGA GeForce GTX970
PSU: XFX PRO550W

You get a power surge error..What gives power to your PC after the UPS? PSU.

First check there.

Hard reboots with no error = usually power cut off = some rail isnt giving enough.

Download HWMonitor, take a screenshot of it and show us the values please.

The 3.3V/5V and 12V rail.

First check there.

How?

The best I can offer is that the 12V rail was running at 11.05V (as measured by a seperate program) last time I checked. Tthis is a relatively new PSU, not even a few weeks old.

Well power cut off, is usually PSU, start from there, aka find another PSU to check, get a friends.

I meant how can I check to make sure that's the case.

I already posted above, apparently you are too active and dont see the edits but still doesnt mean its always accurate.

As i said above.

Try to get a friends PSU to test, usually hard reboots without a blue screen is because the power cuts off which indicates to PSU first, and then motherboard.

Dont you have your old PSU? or a friends PSU you can borrow and check if the problem persists?...
Sure as hell sounds as a power problem...

You could always do the good old de-duster... If there is alot of dust inside your CPU / GFX fan.
Lords knows it has fixed alot of weird shit for me...

Windows had some info on the subject, probably worth doing their troubleshooting.

This is an updated calculator for PSUs.
Put in as much info as possible and it will give you total wattage needed

EDIT: The calculator gives something just short of 400W

Doesnt even show the 5v and 12V.

Download Aida64 Extreme, Home Trial version from their site.

Check at the "Sensor" option, report after.

[tehpwner]

Aida omits the 12V
+3.3 V 3.360 V
+5 V 5.000 V
+12 V [ TRIAL VERSION ]

I what aida produces

[potis]

Right..Shouldnt do that, it gave me 11.98 as it should be.

Find a new PSU to test from a friend first.

[tehpwner]

I have a spare one, I'll go test right now I guess.

That's outside of the ATX specs (+- 5%). It's either to small and can't handle the load, or it's broken. If that number is from when the computer was idle I'm leaning more towards broken.
Return it to have it replaced/repaired.

power supply testers are pretty cheap at amazon...

as someone mentioned...blow it out...

re-seat everything hardware wise...
check your memory...
