Hi Guys,

for the last few weeks I had an issue while trying to play games, immediately after the loading screen in a bunch of different games my pc turns off and starts to reboot, although sometimes I can play for a few minutes before the PC reboots.
There were no hardware changes when this problem first occured and I did reinstall win10 in hope of fixing this issue.

I've spent the last few days trying to find a solution for this and read through a bunch of different threads.
Overheating is not the issue, CPU and GPU never went above 60°C.
I ran IntelBurnTest a few times without any issues, with furmark and AIDA64 system stability test I encountered a few reboots but only very occasionally.
I tried my GPU in my roommates computer and it was running games just fine, so I don't think this is the problem.
I think it might be an issue with my PSU, although according to AIDA 64 the volt values seem to be around the expexted value, at least to me. I can't really afford to just buy a new PSU to test if this was the problem.
I never overclocked any part of my PC.

I'm all out of ideas what to test or look for next and frankly what I did until now I was only able to do because I looked it up online, this is a little bit above my level of knowledge.
I hope I've included enough information, I'll add more if I can think of it.

Edit: Here is a screenshot of the statistics tab of the AIDA64 system stability test

And my specs are probably useful as well:

Intel i5-4590
Gfx 970
16gb ram
Mainboard: GA-H97-HD3
PSU: Coolermaster G550M

Everything is approx. 3 years old.

Does anyone know how I could move forward from here? Any help would be greatly appreciated.
 
Solution
mostly means psu could not handle load you might be better to try another one for test and if you could get a new one ,this one still under warranty ask rma .

I've just ran the power supply stress test from occt twice and both times my PC rebooted after less than a minute. Is this a confirmation that my psu is faulty?
