Rainbow screen glitching only on certain games.

[tjhfirefighter]

HEy guys hope someone can help me out here have Acer preditor helios with I9HX proceesor, rtx 4080, 64 gb ram, and 2tb ssd x 2.
All of a sudden 2 days ago started getting rainbow screen glicthes on Squad, CSG, and intermittently Cyberpunk,
Arma and other games nothing but those three problems. No other apps such as netflix nor amazon prime video have problems so based on this I dont believe it is related to faulty screen or screen cable. Have tried to see of ram related by switching back to original and no luck. Not sure how to fix.
Secondarily this all started after easy anti cheat started giving me ms overlay and cannot find app.
Have solved that issue but still no luck with screen glitches.
Seems to be a software issue but cant find it.
PLease help
