Title: RX 580 crashing in games and stress test, need help diagnosing

Specs:

• CPU: Ryzen 5 3400G
• GPU: RX 580
• RAM: 8GB DDR4
• PSU: 650W true rated
• Storage: SATA SSD

Issue:
When I play F1 25, the game runs fine at first. After a few minutes, the screen freezes. It stays frozen for around 10 to 20 seconds, then crashes.

What I tested:

• Ran Windows Memory Diagnostic, no RAM errors
• Ran FurMark, it crashed after around 10 to 15 seconds
• GPU temps were only around 49 to 50°C before it crashed
• After FurMark crash, I still had display

Extra info:

• This issue happens mainly under load
• PC does not fully shut down, only the GPU seems to crash or hang

What I need help with:

• How to properly diagnose if this is a GPU hardware issue or driver issue
• Any tools or steps to test GPU stability deeper
• Possible fixes before I consider replacing the GPU

Thanks in advance for any help.
