Question PC seemingly randomly causes screens to go black and GPU fans to go to max speed

Jan 16, 2023
Hello all!

I have an odd issue. Basically, seemingly randomly, my PC will just turn off both of my monitors and my GPU fans will turn to max speed, and the computer becomes completely unresponsive until I turn it off manually.

This is actually an issue I had with my previous PC, which I have since gotten rid of and replaced it with a brand new one. However I did take a 500GB SSD and a 3TB HDD, along with 2x8GB of RAM. Currently, the HDD holds some games that I have transferred over as I didn't want to reinstall them and the SSD is currently wiped but not formatted.

Since I had been having issues with my previous build this is everything I did to try to fix it:
  • Run memcheck on the 2x8GB of RAM from my previous PC (no errors)
  • Unplug from a UPS and plug directly into the wall outlet
  • Plug the PC into a different wall outlet
  • Update Bios
  • Install and Update drivers
  • Reinstall graphics drivers
  • Checked Event Viewer for any errors (none found)
  • Run Chkdsk on the 3TB SSD (no errors)
  • Completely unplug the SSD and HDD
My Specs are:
  • Intel Core i7-13700KF 3.4 GHz 16-Core Processor
  • Deepcool AK620 68.99 CFM CPU Cooler
  • MSI Ventus GeForce RTX 4070 Ti 12GB GDDR6X PCI Express 4.0 Video Card RTX 4070 Ti VENTUS 3X 12G OC
  • Asus PRIME Z790-P WIFI D4 ATX LGA1700 Motherboard
  • Corsair Vengeance LPX 32 GB (2 x 16 GB) DDR4-3600 CL18 Memory
  • Corsair Vengeance LPX 16GB (2 x 8GB) 288-Pin PC RAM DDR4 2666 (PC4 21300) Desktop Memory
  • Samsung 980 1 TB M.2-2280 PCIe 3.0 X4 NVME Solid State Drive
  • Corsair RM850e 850 W 80+ Gold Certified Fully Modular ATX Power Supply
  • Windows 10 Pro Build 19045
I am currently at a complete loss for what the problem is and I'm willing to try just about anything, any advice is appreciated!
