Default shutdowns with win10

HI,

I'm trying to run four LL tests on a 990FXA-UD3 Gigabyte AMD FX99370

with a noctua NH-D14 cooler and 32GB of Ram.

This didn't happen initially but at some point this machine began shutting down

after a few seconds of prime95 running.

The monitor shows nothing, nothing wakes the computer up. The fan on the CPU still runs and the PSU is still running but the power switch doesn't switch the machine off.

I'd like to be able to solve this problem.

Can anyone help?

Try running memtest86+ for several hours.

Install some temperature monitoring software. (Recommendations, anyone?) I run my boxes with the side panel taken off when number crunching. You might have to have some more case fans or more powerful ones or upgrade the case.

What is the PSU make and model?

Hmm that PSU might be the problem especially if you have a graphics card in there. This link talks of the machine not shutting down properly. I would recommend a decent Corsair PSU -- will pay for itself in terms of electricity used and not damaging the other components.

I thought it sounded like thermal shutdown issues, like the CPU going into an emergency C6 (deep power down) state due to critical overheating. I guess that might depend on the motherboard and any features like that it may have.

On Proliant servers for instance, critical thermal issues cause an immediate shutdown and it goes into a mini-bootloop until it's cooled off enough to start back up properly.
