CPU overheating? Screen goes black, fans go full speed, audio stops.

My PC has been kinda prone to overheating since I built it but currently I think the CPU is overheating. About 20 minutes in to playing a 3D game the screen will go black and the system will be unresponsive, not returning. To fix this I've tried reinstalling GPU Drivers, spraying out all the dust from the rather big CPU cooler, and reconnecting every PSU cable. I got a temp log using open hardware monitor that seems to show higher temperatures before the crash. Could this be a thermal paste issue? the CPU cooler is honestly kind of a bitch to take out. I have a desk fan pointed at my graphics card sitting in the CD bay, could that be interfering with anything?

Specs: H110M-A Mobo, i5-6500 CPU, AMD R9 390 8GB GPU, 2x 8Gb DDR4 RAM, DEEPCOOL GAMMAXX 400 CPU Cooler, SeaSonic 650-Watt PSU, Windows 10 Home.

Here's a temp log before the last crash, the crash occurred on line 4060 around 19:27. I'm awful with spreadsheets and don't know what this tells me.

Thank you for helping!

This log doesn't display CPU temperature. Try downloading HWmonitor and download CPU-Z.

Open HWMonitor and on the CPU-Z window navigate to the Bench tab and press Stress CPU.

Keep checking HWMonitor for the temperatures under the "Intel Core i5-6500" tab to see if they reach anywhere near 85-90ºC.

Its sounding like it could very well be a Power Supply or GPU issue though, but never hurts to check. We need to dig deeper.

okay so i ran CPU-Z for a few minutes and stopped it when everything started getting really slow, the max temp was 44 C with normal being 30 C so i think it's not the CPU unless i didn't run it long enough

Download furmark and run it. Let it run for about 1 hour and then come back with an update if it crashed, black screened, etc.

Disable any overclocks you have on the GPU if you have any.

so about five minutes or so after stopping the benchmark the screen went black again. does this determine that it's not a CPU, GPU, or driver issue? the PSU is only a few months old and worked great until recently i guess, figured it was expensive enough to not break down as fast. something i forgot to mention earlier, windows always says it's "finishing updates" when i reboot after these outages, then it says update failed and reboots again. this happens 90% of the time after the screen goes out.

Try seeing what Eventviewer tells you.

Win key + R

Type eventvwr in the box and hit Enter.

Navigate to Custom Views - Administrative Events.

Search for any "Critical" errors with an X icon.

If there are any, please tell me what it tells you, if you can.

there were several from today, all due to unexpected reboots (but that might just be me restarting the computer after it blacks out). the one from today says "The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly." in details it says + System

Try removing the GPU and running on intergrated graphics, see if you still get the black screen. If yes, at least we can take the GPU fully out of the equation.

I don't know why, that motherboard is sounding like the culprit here, but we'll see.

Can you make that happen? Run the computer without the GPU for a while and then report back?

so i've been running it without the gpu for a few hours, 0 problems. can't really use any demanding software without the gpu but i ran league of legends fine for an hour or so and ran a CPU stress test with no problems. could the issue be the amount of power the GPU draws? my PC is connected to a power strip along with speakers, monitor, etc. Would using Wattman to limit the power work?

So I RMAd the card and it seemed fine when it got back but after like half an hour of overwatch it shut off again. afterburner is kinda hard for me to navigate but from the looks of it everything is at half setting. should i try to apply my own thermal paste on the card?
