I have a problem where the screen will go black, usually for about a second, at seemingly random times during steam games. This has happened for the following games:

sekiro
hollow knight
don't starve together
Plate up
code vein

The problem doesn't seem to trend with more graphically demanding games, or be associated with higher GPU temps or fans running. Most of the time the game will run fine after the black screen, though some like hollow knight will lock up and need to be restarted. Most often happens 10-30 minutes into gameplay, and does happen again some time later if I keep playing in the same session. So far I've only been able to reproduce this problem while playing steam games. For example I have not yet encountered the issue while playing games through epic but I'm still testing.

The problem is relatively recent, I've had this pc about 3.5 years and I first had these black screens sometime fall '23

From what I've read online this issue seems to most resemble an issue described as being due to mismatched/ an issue with monitor resolution, but I've been using these same monitors for the entire life of the PC and the problem is newer.


Specs:
CPU: ryzen 5 3600
GPU Radeon RX 5700
Mobo: Asrock x570 phantom gaming 4
Monitor: Tested on Lenovo Len 27q-30 1440p/75Hz and ASUS VP249 1080p/144Hz
RAM: Would need to look up the specifics but 2x 8GB
Windows 10

What I've tried:

Updated windows and graphics card drivers
tested on different monitor and cable
verified game files
re-installed steam
turned off Freesync and vsync
Played on 1920x1080 instead of 2560x1440

any ideas?
