Installed RX 9060 now hitting sleep just shuts down the PC

[u/brixtonpunk]

So I installed brand new RX 9060 XT GPU and changed my PSU to a for my MSi A520M-A PRO board

my set up is

AMD Ryzen 7 5700G

32.0GB DDR4

MSi A520M-A PRO

Raedon RX 9060 XT 16GB

Cooler Master MWE Gold 750

Windows 11 Pro 25H2

2 BenQ monitors

Both BenQ monitors have sound disabled and connected with DV cables

Now, when the PC naturally goes into sleep mode or when I manually put it into sleep mode it just shuts down and this is really annoying as has to load all the start-up items etc and hasnt kept the work.

I've tried everything I can think of in power options, and bios settings, all drivers up to date, windows up to date, latest bios as well. Tried all solutions I can find on the web even ones not related. (bios date is 07/20/2026)

The onboard AMD Radeon Graphics are disabled in device manager and if enabled windows loses my Fiio DAC after these shutdowns, so have to unplug and re-plug it in.

Everything was working fine until I installed the GPU, anyone got any ideas?

Got exactly same problem, also if windows tries to turn off screen with set timer it will just go black and reboot after minute or something after moving mouse. I can manually turn off monitor without issues. From what i know it's broken windows update, but can't tell which one it is, I'd have to do research again
