I got back from my vacation and I played different games (Overwatch, Firewatch, Gta V, CSGO) without any problems. So yesterday I wanted to play Rainbow Six Siege again. After a few hours my monitor started blinking on and off. I restarted my PC but it kept happening (not just in game, but everywhere else).
Today I played R6 again, and the same thing happened. After a few hours of playing, the monitor starts blinking. Restart the PC - still happens.
But if I leave the PC off for a bit, and then come back, it doesn't blink.
So from what I understand, If I leave the PC off, it goes away? Could it be that something is overheating and causing the problem? Or is my monitor dying? It's 6 years old.
I had MSI Afterburner running the entire time, and everything was fine according to stats.
This is so weird, I have no idea what's causing this to happen. It worked perfectly fine for 3 weeks until I first played R6. Is it a software or hardware problem? Is my GPU or monitor faulty?
