PC was built in 2017 (spec down below) and has been rock solid ever since, until 5 days ago...
PROBLEM: random black screen, PC stays on (can tell because I still have sound), could happen when idle, browsing, while booting or gaming (more so gaming so far). If it happens while booting I can see the POST OK but when it loads into Windows the screen just goes black. Event viewer shows nothing leading up to the event, only thing it logs is when I am forced to power the PC down via the power button. Windows Notifications has been sporadically reporting 'Display Driver Failed To Start'.
WHAT HAVE I DONE TO DIAGNOSE IT:
After updating the GPU firmware yesterday I left Unigine Heaven running for 11 hours overnight (GPU temp leveled off at 67°C) and did not have a single black screen issue so thought I'd fixed it but today it's black screened several times while gaming and also while booting.
I've ordered a new PSU to either fix it or rule it out, it's arriving in 2 days so I'll know if it has any effect after at least 2 days of use. Other than that I'm at a loss as the problem is so random that I can't nail down what is causing it. Obviously if I had access to spare hardware I'd start swapping out the GPU and RAM and go from there.
Any ideas? This is REALLY frustrating.

WHAT HAVE I DONE TO DIAGNOSE IT:
- Fully update Windows
- Run DDU and clean reinstall latest GPU driver
- Run DDU and clean reinstall previous 3 GPU drivers
- Updated GPU firmware using Nvidia's firmware tool
- Ran memtest64 (no errors)
- Ran Windows Memory Diagnostic Tool
- Turned off XMP in BIOS
- Removed 1 stick of RAM
- Swapped the RAM sticks over still leaving just 1 in the system
- Plugged my monitor into onboard graphics (this works fine)
- Ran GpuMemtest (no errors)
- Ran SFC Scan (no errors)
