IX Code - Random shutdown on load.

I'm trying to diagnose a problem I'm having with my new setup, whenever the system is under heavy load (games mostly) my system will randomly shut off. I say randomly because It doesn't seem to be related to temperature loads, it could happen after 5 minutes, possibly after half an hour or more.

At first my thinking was that I was running hot enough that the "7700k temperature spike issue" was causing one core to suddenly shoot over the maximum and the system emergency shuts down, so I delidded the CPU and removed my overclock for the time being. Now when running say OCCT, I never see any core go over ~70C, so I don't think it's heat related, also the games I'm seeing this happen in don't put nearly so much stress on the CPU.

Any thoughts as to further troubleshooting steps? I don't want to RMA until I've ruled everything else out.

Hi dani.arde

The first thing I suspect with shutdowns is the psu but isn't always the cause, try running your system at default settings and see if it still happens.


Hello,

thanks for your advice. I already did that, but I can try again.
(Also my PSU is 2 year old, so I will look around for a replacement unit to test if the problem persist.)

Finally here it is my followup.
The problem gradually got worse in the past months and in the meantime I ruled out everything but the motherboard, CPU and the PSU.
Then I noticed that disconnecting some components (i.e. 1 or 2 HDDs) made my PC lasts longer under load without shutting down, so I replaced the PSU and now everything is working fine.

Thanks again for your help.

I'd like to followup. Got the replacement motherboard, updated the bios to 906, re-setup all the bios settings. Just completed the 30min OCCT power supply test with flying colors. A little more time to settle in may be in order, and a longer stress testing session, but I'm prepared to call this fixed. Inspecting the defective motherboard doesn't reveal any smoking gun, however.

Thanks for your help, Nate.

Thank you for the followup. Please let me know if it happens again or not, so I can decide to write Asus for a RMA too.

The only thing I can think of would be an internal short of some kind, that only is an issue when under load due to the higher vibrations or voltages from being under load. We'll see what Asus says when they finish with the RMA, if they tell me anything about what the fault was, I'll post it here.
