Question Persistent Game Crashes - Radeon 6600? Or Something Else?

[GW1914]

Hello! I have recently been experiencing persistent crashes, complete reboots - but only while playing games. No issues during other tasks. Temps for CPU and GPU always remain between 30-60 C.

Sometimes, this happens immediately when the game is opened - especially the more graphically intense ones. Other times, it may take 5-15 minutes for it to crash.

Does anyone have any suggestions based on the following? I'm thoroughly stumped 🙄

Current setup (Recently upgraded)
CPU: Ryzen 7 5700X
MB: Gigabyte B550M
RAM: 32 GB XPG Spectra D35
GPU: Radeon RX 6600
SSD: 2 Samsung 860 EVOs (512 and 1 TB, respectively)
PSU: CoolerMaster Masterwatt 750 (3.5 years old)
OS: Windows 11 Pro

What I have tried

• GPU: Uninstalled and reinstalled Radeon drivers (using their Cleanup utility each time)
• GPU: Used Eco mode in Adrenaline
• GPU: Undervolted the GPU
• GPU: Rolled back drivers (tried a set from 2 months ago, and a set from 1 year ago)
• GPU: Switched to my previous GPU (Rx 570) and tried to install drivers. Computer crashed during installation of Adrenalin. Was able to install Pro drivers. Game then crashed as usual.
• GPU: Limited the GPUs FPS to 60
• GPU: Reseated GPU
• GPU & CPU: Stress tested both of them with OCCT for 10 minutes at near 100% capacity - no crashes, interestingly
• CPU: Installed updated drivers
• RAM: Ran Windows Memory Diagnostic - no issues found.
• SSD: Ran Samsung Magician and CrystalDiskInfo and each drive is between 95-100% health.
• BIOS: Updated to newest version
• BIOS: Enabled XMP profile so that RAM operates at 3200 mHZ
• OS: Reinstalled Windows 11 (deleted all partitions and started fresh)
• PSU: Replaced the old 8 pin connector with a new one (modular PSU)

In spite of all of these efforts at troubleshooting, the problem still persists...

Thank you for your time and help!!!

GPU: Uninstalled and reinstalled Radeon drivers (using their Cleanup utility each time)
Use DDU to remove all GPU drivers(intel, Nvidia and AMD) in Safe Mode, then manually install the latest GPU driver in an elevated command, i.e, Right click installer>Run as Administrator.

BIOS: Updated to newest version
For the sake of relevance, please mention the version for your BIOS that you'd flashed to. Also, did you clear the CMOS after verifying your BIOS flash was successful?

OS: Reinstalled Windows 11 (deleted all partitions and started fresh)
Did you recreate your bootable USB installer for your OS? Did you install the OS in offline mode, to later install all drivers manually in an elevated command, to later connect to the internet to update the OS?

PSU: Replaced the old 8 pin connector with a new one (modular PSU)
You might want to source(borrow, not buy) a reliably built PSU from a friend or neighbor that can deliver 550W of power to the entire system and see if the issue persists.
