PC needs to rest a few hours after bootloop

[cynexit]

Alright, this is an odd one.

I have a PC that sometimes crashes (no bluescreen, screen just goes black) and then directly tries to reboot for a second, then goes out again, tries to boot again for a second, and so on and so on...

If I cut the power, plug it back in and try to restart it, the loop just starts again. If I wait for ~2h and try it again, the PC magically boots again.

At first I thought this would be a PSU issue, but even when I switch the PSU directly after the crash everything stays exactly the same...

 

Has anybody seen something like this before and can give me some pointers?

Defy sounds like a heat thing if you have to give it a break. Check coolers for dust and do things

For a few hours?

 

CPU's cool down quickly when they are off.

Next on the list, i would suspect the MOBO. check for bad capacitors.

CPU and GPU are in a custom loop and pretty cool, the only thing I could think of are the VRMs on the MoBo, but they are at ~49°C according to Aida, the PSU is at 37°C according to Corsair Link. All of these sound "alright" to me, did I forget something?

I tired a AX860i and Seasonic Prime, both show the same behaviour.

None of them look bloaty or bigger than they should be, anything other to look out for in optics?

Tried with and without the gpu?

 

Fuck never mind they're in a loop. I think its time to RMA the mobo.

Alright, I have a spare Asus X99 MoBo somewhere, will give it a shot tomorrow and report back if anything interessting happens.

 

Thanks you two!
