AMD Radeon RX 5700 XT, random no monitor signal

Hi all!


I am having this weird issue, it started a week ago.

Randomly the signal to my monitors cuts out, and I have to do a hard restart (using the reset button in my case does not help, I have to hold down the power button). When the signal cuts out there is first a green line or flash and then I get the no signal from my monitor.

I don't know if this is related but, sometimes when I start my pc the screen freezes on the login screen (It's not a problem with my mouse or keyboard because the time on the screen does not update). 

I bought my pc at caseking, which means I didn't assemble the pc - they did. Any ideas?


Thanks in advance.


What I tried / additional info:

- Reinstall drivers using DDU (I reinstalled the amd software adrenalin).

- This is a relatively clean install of windows (1-2 months old).

- When using FurMark GPU stress test, the black screen does not happen.

- dxdiag does not show any errors (I can post the output if asked).

- I do not have any overclock software installed.

- The crash mostly happens when I'm gaming (It crashed while playing CS:GO and MTG: Arena), but this could be a coincidence.

- Both of my monitors are basic 60HZ monitors and are connected with hdmi.
