CPU: Ryzen 5 3600
GPU: XFX Radeon RX 5700 XT THICC III Ultra (Product/Model number: RX-57XT8TBD8)
Motherboard: Asus TUF Gaming X570-Plus Wifi (BIOS 1707)
Storage: Intel 660p 512GB SSD, Seagate Barracuda Compute 2TB HDD
PSU: EVGA 100-N1-0650-L1 (650W)
Case: NZXT H510 (3 Case fans, 2 front intake, 1 rear exhaust)
My PC crashes during long periods of gaming (1-2 hrs of continuous) with the screen going black (no signal), fans turning off (RGB stays on but does not move), which requires me to turn off the power supply and turning it back on again. At first I thought it was a GPU issue whether it be drivers or otherwise, and I tried these solutions:
1) Flashing newest motherboard BIOS.
2) DDU and reinstall driver 19.11.1 WITH SOFTWARE
3) DDU and reinstall driver 19.11.1 WITHOUT SOFTWARE
4) DDU and reinstall driver 19.12.1 WITH SOFTWARE
5) DDU and reinstall driver 19.12.1 WITHOUT SOFTWARE
6) DDU and reinstall driver 20.2.2 WITH SOFTWARE
7) DDU and reinstall driver 20.2.2 WITHOUT SOFTWARE
8. DDU and reinstall driver 20.4.1 WITH SOFTWARE
9) DDU and reinstall driver 20.4.1 WITHOUT SOFTWARE
10) Install newest AMD chipset drivers
11) Disabling D.O.C.P.
12) Changing PCIe version to 3.0 instead of 4.0
13) Running all games as Administrator
14) Running Unigine Heaven and AIDA64 stress tests with temp monitors (NOT OVERHEATING)
In my DxDiag and MSInfo32 files right before crash, this message comes up: Fault bucket 0x1B0_DxgkrnlLiveDump:804_Status_0xC0000001_Driver_atikmpag_failed_DdiStartDevice_AMD_StartDeviceDiag_dxgkrnl!DxgCreateLiveDumpWithDriverBlob, type 0
I don't know what it means, but a technical support rep at Blizzard told me that this is what is crashing my whole PC.
I also realized that my PSU is ranked E (Dangerous in many situations) on the PSU Tier List, with some forum members commenting that my PSU would be unable to feed power to my entire system.
I am now wondering whether my issues stem from GPU, PSU or both. My case has a power supply shroud, but there are ventilation holes on the shroud right below my GPU that might feed hot air to my PSU (right below GPU). My GPU regularly reaches 80 degrees Celsius, and I heard that my PSU's maximum operating temp is 25 degrees C. Could PSU overheating be the problem? If it is a PSU issue, overheating or otherwise, I was going to buy the Corsair TX650M (650W, 80+ Gold, B+ on PSU Tier List) with a listed 50 degrees C max operating temp, with reviews saying that it could withstand very harsh operating conditions. Would this be a recommended PSU?
Any help or suggestions would be very much appreciated. Thanks in advance.
EDIT: Fixed the issue completely, computer doesn't crash anymore. Issue was my PSU, the GPu would trigger overvoltage protection. Changed the PSU for a better unit (Seasonic Focus GM-850) and issue is completely resolved. Moral of the story, don't cheap out on the PSU and read reviews.
