After 10-30 minutes, while playing the Higher-end game my monitor will change to the majority of the color on the screen. Say i'm looking at a forest, the monitor will turn all green. After about 5-10 seconds, monitor says "No Signal" then reboots back with my youtube video open and game closed, but the screen for the vid is black and it goes back to normal after I click play. Searchbar is black over what i'm typing, this has happened about 2 weeks after I built the pc. I bought 2 used parts, PSU and GPU, I suspect it's one of them I'm going to replace both regardless, but does anyone know a temporary fix or they can tell me exactly what the problem is? Been going on for about 3 months
