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
 
Also if i don't restart my pc after the incident, like 1/3 top of my screen while doing ANYTHING will turn black for like 5 seconds then go back to normal
 
I've also had in War thunder a game that usually runs fine and 95% of the time doesn't have the incident, sometimes my plane and parts of the ground will turn fully blue for some reason idk why
 
1.Try reinstalling GPU drivers with DDU.
2.Perform Windows 10 in-place upgrade.

3. Try replugging (unplug and plug cable) monitor into graphic cards, do the same with power cable while the PC is off.
4. Clean the inside of your computer with compressed air.
