Hey, so I recently built a new PC with these specs:
CPU: AMD Ryzen 5 5600G
iGPU: AMD Cezanne (I bought this all just before the GPU crash, so an APU made sense)
Mobo: Gigabyte B550M DS3H
RAM: Corsair LPX 16GB (2 x 8GB) DDR4 3600 C18 (PC4-28800) 1.35V
PSU: Seasonic S12III 650W
I can't confirm that for 100% but when I have HWiNFO always running in the tray, as the startup app my machine shutdowns or freezes immediately in a second every few days/week.
How do I know it? When I disabled HWiNFO and it's not running anymore those problems don't occur anymore.
