Need help dianostic black screen error

[e22big]

Hi guy, 

 

Recently my computer has a weird bug where the screen just turn back and won't turn back up, forcing me to do a system restart. This happened especially happened after I game, I often encounter it after closing Cyberpunk 2077 or Total War. Sometime the screen just turn black but the system is stil responsive (as I stil hear music playing in the background) or sometime it just freeze (sound turn buzz and then silent) 

 

I suspect 3 things actually: my Nvidia driver, my GPU undervolt profile, and Logitech G-Hub

 

I have had this sort of problem before just last week when I tried my max overclock profile in game, running DDU and a fresh driver install did solve the issue completely so it's definitely a driver that time. Because of that I no longer use my overclock profle on 3080 and undervolt it instead, gaming in the past couple of days had been very stable but just today I start to have this sort of issue again and it happened even when I am not gaming - I do run MSI Afterburner in the background all the time, in minimised windows so it's possible that it's causing an issue. 

 

As for G-Hub, well, it has a history of causing my game crashes in the past and I noticed that when I experienced a hard crash like this, G-Hub lost all of my custom profile and reverse to its default stage as soon as I turn my system back up - it is the only program that show this behaviour so I sus it just a bit. 

 

Naturally, I tested my theory as soon as I have the time, turning them off one by one and try run games with each of these turning on one at a time - but the crash just quietly disappear. Still I fear that it will come back to bite me tommorow or some other time. I use this computer for both work and game so it crashing randomly during work hour is just unacceptable and I hope some of you guy here will be able to shed some light as to what step I should tried next to recreate and identified the issue.

Just like an overclock an undervolt can be unstable, so you likely also went a bit too far there.

If you need it to be stable then maybe stop mucking around and just run stock?

tried that just now and it crash even after stock

 

I am starting to think that this may be a software issue Cyberpunk is known to crash from driver after all
