Hello guys, I am not very tech savvy, but I have built 3 gaming computers over the past 10 years (I build a new one every time I upgrade). A couple of months ago I decided to build another one and I have been plagued with my PC shutting down when playing certain games. It does not shut down when playing Modern Warfare on Very High Graphics, but when playing the Epic Games title "Control", my computer is able to handle the game just fine for about 10-15 minutes. Then it eventually crashes the computer and it stops working. The screen goes black and the speaker has a faint buzzing sound. The PC power indicator light stays on and the computer never actually "shuts down", so I need to hold the power button to reset it. I have tried Ctrl-alt-delete and various other keyboard methods, but the PC remains completely unresponsive (and the buzzing sound is persistent until I reset it). The PC starts up fine and there are no errors or warnings for Safe Mode or anything like that.
Not sure if this helps, but the PC usually crashes when I pause the game and go into a menu to adjust a character upgrade.
I have installed MSI afterburner and repeated tests with the game while observing my PC's CPU and GPU temps. The CPU never goes above 74C and the GPU never exceeds 65C, so it shouldn't be crashing from overheating issues.
Specs-
Windows 10 64bit
ASUS z390-E motherboard with latest bios version 1502
Intel i9700K overclocked with XMP2 profile
Noctua NH-L9x65 CPU cooler
Single RTX2080Ti GPU, ASUS ROG Strix 11GB (not overclocked)
64GB TridentZ RGB ram running at 3200mhz
1000 Watt PSU, EVGA Gold
M.2 SSD Samgsung 970 Pro 1TB for operating system install
1 other M.2 SSD 512gb, another 512gb Sata SSD, a 3TB 7200 HDD, and another 3TB 7200 HDD
Surge protector outlet strip
Case fans, x2 200mm and x1 120mm fans
GPU is connected to a Pixio PX329 monitor (2560x1440) via Display Port. This monitor caused no issues with previous PC that I had.
Drivers for GPU are up to date
I also installed ASUS Armory Crate and used it to update the MOBO drivers for the RGB controls for the MOBO itself as well as the RAM and GPU through AURA RGB.
Prior to using the new 1000W PSU that I have now I was using a brand new NZXT C850, 850 watt PSU and experienced the same issues.
I also recently discovered that I had not changed the CPU over voltage jumper on my motherboard to be functional, so I switched it from the 1-2 pins to the 2-3 pins and I thought that may have helped with my issue. Unfortunately nothing changed and I still encounter the same problem.
By the way, I have also tried doing these tests with the overclock turned off as well. The only difference that I noticed is that the CPU temps don't rise as high when not using the overclock, usually around 65C, before the PC crashes.
If anyone has any idea what could be causing this problem, help would be greatly appreciated!
*Update*
After running a Heaven Benchmark with DX11, Ultra Settings, Extreme Tesselation, and full monitor resolution, nothing caused my PC to crash. Temps never rose above 60C.
I then ran a Furmark GPU Stress Test at default resolution for my monitor (2560x1440) at 4K with 8x MSAA. After letting the test run for 5 minutes, my GPU temp had risen to 61C and was staying steady for the last 3 of the 5 minute test.
However when I closed Furmark to end the test, my PC screen went black and stopped working. This shutdown was different from the others that I have experienced. Normally, the screen goes black, and then the monitor stops receiving power from the PC, so the monitor goes into standby mode. However this time, the monitor never went into standby mode, it stayed on with a black screen, while the PC was still completely unresponsive.
I am curious if this is a GPU issue due to PSU power draw issues? I do have two separate GPU power cables plugged into the PSU for my RTX 2080Ti.
