Is my monitor going bad or its something else ?

[kizx]

Hello, sometimes I feel that even with the perfect G-Sync settings recommended with 141 fps at 144HZ, V-Sync in NVCP something is wrong, not really tearing but almost-ish. almost like if i move super fast in-game I see something but its so fast that i cant get a grasp on what that is. Also sometimes it feels like micro-stuttering but not like it would happens from time to time and get better it feels like its always there like if I move my character some UI will shake so fast that i wont be able to tell if it does really but it does.

I dont feel that way when I just first started playing or sometimes I dont feel that way when i have a Youtube video playing in the background thats very weird.

I can still play and stuff but sometimes i wonder if its my monitor going bad or something else because when i first open my monitor and its very cold there is purple/green/yellow lines but once its warm after 20 seconds its gone so maybe everything else is good and sometimes it feels weird because my display/cable are going bad and its messing with my drivers ?

Another weird thing happening right now but what i mentioned above was already happening way before that but it could be related : is that if i restart my pc my bios will say press f1 because something was unstable or something and googling it says that its because of cmos starting to go bad i wonder if that could be related and if i really need to change it. because if i just shutdown my pc and turn it on then its fine Also if i restart my pc right after turning it on it wont do the error just if i leave it on for a while then restart.

Also it could just be that my monitor is not good with gsync.before i perfectly install my driver with ddu i had insane flicker but now after i ddu they are gone 95% of the time but there is still some glitches from time to time depending on the game.
