GPU crashing on certain PC

[drafael0220]

Hi. My brother has one pc each. Here's the specs first.

Mine:
Windows 10 PRO Version 21H1 OS build 19043, 1165
GPU: Sapphire RX 580
Motherboard: Aorus B450M
CPU: Ryzen 5 2600
PSU: Corsair CX550M
RAM: 16gb Corsair DDR4 3200MHZ dual stick
Storage: 240gb ADATA NVME

Brothers:
Windows 10 PRO Version 21H1 OS Build 19043, 1110
GPU: HIS RX 560
Motherboard: Asus Prime A320m-k
CPU: Ryzen 3 3100
PSU: Deepcool 500W
Ram: Hyperx 8gb 2666mhz Single
Storage: 256gb Gigabyte NVME

My brother's motherboard, cpu and ram were bought recently. then after that when he is using his GPU RX 560. There are random black screens. the fan on the case would be still on but the keyboard light would turn off. It always happens just after 5 mins of any activity. But when he uses my GPU RX 580 everything works fine. Then I tested his RX 560 on my pc and everything works fine. Any help would be appreciated.

Tried so far on my brother's PC:
- Reinstall OS
- DDU GPU drivers and reinstall.
- Windows update is latest
- BIOS Update to Latest Version 5606 - 2021/08/04
- RAM is set to auto 2666mhz,
- did not change anything on the BIOS
- reseat everything

Thank you!

I mean you have a bad psu in your brothers system and yours is a good quality one so quite obvious where the problem is.
