Question My Pc Restarts continuously after it has run for a while

[JimboSlice240]

When i run my PC for a while it stops and gets stuck in a reboot loop.

My pc runs at:
~28 Degrees Celsius When Idle
~48Degrees Celsius When Gaming

So i doubt it's thermal throttling but im not good with computers.

Any Help much appreciated.

Specs:

Motherboard: EVGA Z170 FTW Motherboard
CPU: i7-4770k
PSU: EVGA NEX650G
RAM: GSkill 16 Gb Ram
GPU: GeForce GTX 1080
SSD: Samsung 750Gb

When the system reboots, does it do what looks like a Windows reboot (the software closes and the screen shows "rebooting") or does it just go off and re-start?

It just shuts off and gets stuck in a reboot loop

Well that seems like a hardware issue then. In a case like this it may be a bit hard to identify the faulty component without swapping parts. First, a couple more questions: was anything in this build overclocked? Is there any hint of electrical instability in your area as in brownouts or other devices flickering?

I can suggest a memory test, Memtest86 that can be run from a bootable disk or flash media. Assuming the system is stable enough to run this it loops around until manually shut off and shows the number of errors detected since the run began (if any)

It's not overclocked and i've reset the bios
I cant see or smell anything burnt or lights flickering

I used a psu bridge to test if that was the issue but after running it for a while i didnt find any issue

I'll try memtest86 and keep you updated
