Computer cuts display and acts like it's overheating even though it isn't

Hi all, I've found these forums while looking for a solution to my current problem but have been unsuccessful in finding one, so I thought it was time I made my own post.

I recently built my first desktop rig, and at first everything was great. However since my computer has be acting as if it is overheating whenever I close a game or sometimes when I reboot it. What I mean by acting like it's overheating is that it cuts the display, and usually runs fans at full blast. If I let it sit like this it never seems to change or improve even after 20-30 minutes. The only way I could stop it was to manually power it down, flip the PSU power switch off, unplug it, wait for the electricity to leave the system, then hook it all back up and power it on. Sometimes this doesn't even work, seemingly dependent on how long it's left unplugged.

As I mentioned this almost exclusively happens when I exit games that usually put a load on the computer (like Overwatch, Battlefield 1, and now the Battlefront 2 Beta). The other times it happens have been either when I start the computer back up, it will load the desktop and then after maybe a minute or two throw another fit and I have to go through the whole process of restarting it again.

Thinking it might of been having heating problems I downloaded SpeedFan and had it log tempuratures of my GPU and CPU while playing Battlefield 1 at High~Ultra settings. I got around 100fps the whole match, my GPU capped at 65 degrees Celsius and my CPU at no more than 53 degrees Celsius. Since these temperatures are no where near concerning, I thought it might be a power issue. I've started using ASUS's GPU Tweak program to try and limit the power that my GPU consumes. I've incremented it to 90% and then 80% power target but the problem still persists. Before I posted this I had to actually restart my PC a total of 3 times, and when it did finally load it told me Windows had not loaded properly. I ended up loading into Windows anyway (because I didn't have a copy to tell it repair with), and all seems to be working fine for now. I got my copy of Windows from a friend who was able to give me an install on a USB, which isn't the most reputable source, but it was more appealing than buying the OS at the time.

I've also updated my GPU driver, BIOS, and all that jazz. I'm really at a loss for what could be happening, unless it's some sort of Windows problem, but I'm not sure what could be wrong with the version of Windows 10 that I have.

Some things that might be worth noting: my GPU usually turns a bluish white color with it's lights whenever my computer "overheats", while the CPU lights stay their preset colors. I have Windows installed on my SSD, and my HDD is just for extra storage. I recently my monitor, and the problems have been happening more frequently since getting it, but I feel that may just be a coincidence because it happened 2-3 times prior to me getting it when I was using a widescreen TV.

My System Specs are as follows:
Processor: Intel Core i7-7700K Quad-Core 4.2 GHz Kaby Lake LGA 1151 91W BX80677I77700K Desktop Processor
Heat Sink: Cooler Master Hyper 212 EVO Processor Cooler
RAM: Corsair Vengeance LPX 16GB (2 x 8GB) 288-Pin SDRAM DDR4 3200 (PC4 25600) Desktop Memory
HDD: Western Digital WD20EZRZ WD Blue SATA III 3.5" 2TB Hard Drive
SSD: Samsung 250GB 850 Evo 2.5" SATA III SSD
Motherboard: ROG STRIX Z270F Gaming
GPU: ROG STRIX-GTX1080-A8G-GAMING
PSU: CORSAIR CS-M Series CS750M 750W 80 PLUS GOLD EPS12V Semi Modular Power Supply
Monitor: ASUS VG278Q 27" 1080p 144hz Gaming Monitor
OS: Windows 10

I'll run some antivirus and report if it comes up with anything, but I would greatly appreciate any advice or guidance than you can offer. I'm truly at a loss for what the problem could be. Thank you for any time and help you can offer.

  1. First thing to check, test your video card in another system with a known good power supply. Test your system with another power supply. Reseat the RAM, try with one RAM stick at a time. The CS series from Corsair is almost their lowest range, not a good idea to use with a high end CPU and video card. It's like running a racing car on used tires.

  2. I tried reseating the RAM. I booted with only one, played a game of Overwatch, no crash on close. I put in the 2nd stick, played a game, no crash. I played some rounds in the new Battlefront 2 beta, still no crash. Thinking that maybe it fixed It, I continued playing the beta for the night. Closed game, came to report tentative success just for my PC to "crash and prete d it's overheating again right as I'm going to type.

    Unfortunately I won't be able to test the PSU and GPU in the way you described, @hang-the-9. This tower is the only one I have and I don't have any spare PSUs unless I was to order one.

    Test the system for a few days on one RAM stick. Do you have any friends that can loan you a video card or let you test yours in their system, same thing for a PSU. The issue with finding your issue for sure is that at some point you are stuck with a few possibilities but need to swap out parts to verify.

    I might be able to test my GPU with my friend's rig if he's free sometime soon. The only problem will be finding time when we're both off work and willing. I'll try keeping my system on one RAM stick for a while in the meantime, and see if the problem still occurs.
