Hello @toamna2012, I’m sad to hear you also have this problem. Can you see on any of your logs if you find NVRM: Xid 61 errors? Since you’re with AMD Ryzen this thread should be of interest for you.
Edit: I contacted ASRock yesterday with a carefully written explanation to my problem (that occurs on Linux and Windows) and all they can say is also “We don’t support Linux”. It’s annoying and sometimes it seems they aren’t reading.
