Recently I've been playing Yakuza 0 and it frequently locks up with a solid colour screen and I need a hard restart. The game has a known issue with my 480 so fine. I tried to play GTA V for the first time legally today and it had a bit of screen tearing and locked up in the first cut scene. I never had trouble with the 'alternative' version I played before. I had this problem before which lead to a full platform upgrade. I tried to play Subnautica and it crashed right away as well. How can I identify the problem? It could be my CPU cooler. I tried a burn test and it didn't crash. It could be the GPU, though I really hope it isn't as they are not cheap to replace. According to event viewer, they are always kernel power 41 errors.
Do any other errors show up in event viewer/reliability history... IIRC 41 is 'the pc unexpected shut down and we don't know specifically why' error code. But off the top of my head it could be any one of the following [and more besides] - Drivers RAM Overclock that isn't 100% stable Overtaxed PSU Overheating Windows power settings set to something your hardware doesn't like/power saving kicking in when it shouldn't. Without a more specific error/bugcheck to point at a potential culprit... ¯\_(ツ)_/¯ EDIT: FWIW here is the MS docs page on the error, 'Scenario 3' most closeley resembles what you described. - https://support.microsoft.com/en-gb...1-error-the-system-has-rebooted-without-clean
Thermals seem to be the issue. I have my case on a shelf and hot air was coming out the exhaust. I tried pulling it out and playing subnautica. It played for a few minutes before crashing again. This time I got a CPU thermal error on boot. It seems I need to upgrade my Noctua NH-L9i with something a bit beefier. I plan on moving everything into an mITX case soon but haven't settled on one. Any suggestions for a decent cooler that would be suitable?
Depends what consititues 'suitable'... if you've only got space for an L9i or similar, there's not much you can do. anything appreciably better is also going to be appreciably bigger. FWIW even Noctua say the 6700k is pushing it for the L9i. 'Recommended with good case ventilation only' is what the specs page says.
Something like HWInfo and have it log to file... even if it does keel over you should see what the temps were just before it did.
Something like hwmonitor or hwinfo will provide temps for most of the components in the PC, and you should be able to see from those at idle, and then under different loads pretty quickly if temperature is a problem. I always have gpu temperature displayed whilst playing games, just for peace of mind.
Idle temps Spoiler Reading 1 temps Spoiler Reading 2 temps Spoiler Reading 3 temps Spoiler Crash&^%$ That was the best way I could think of posting readings. I opened subnautica in windowed mod lower rez so it didn't take the whole screen and took screenshots until scratch. The first one is idle.
your cpu is overheating... it's hitting 99C on one core and not far behind on the rest... much more than that [105C iirc] and it'll switch off to prevent damage. And that's not even at anything approaching fully loaded either.
It's nice to confirm the cause. I will stick to retro games until this is sorted. First a case, then a cooler.
You might want to crank the cpu fan up to full, underclock/volt it and/or use the power saver power plan in windows... It'll hobble performance a smidge, but it might be the difference between it keeling over and not.
The power change was easy, I have a fan splitter on the way to collect a second 200mm fan on the top. I will look into how to undervolt and crank up the fan speed.
You have big differences between cores under load as it is building temperature, so probably poorly seated cooler or it or the IHS isnt very flat. Thermal goo can only do so much. 1.45v is high no wonder it is cooking.
I have a 200mm fan on the top but not enough MB headers. I ordered a flan splitter which should arrive soon.
