This happened yesterday when I wanted to start Dota 2. The colours of the whole screen become distorted with red pixels flashing around. Restarted the pc and the same thing happened. So i disconnected my GPU and connected straight to the motherboard's display. Same problem. Unplugged the pc for a few hours and the problem went away. I assumed it was a one time thing so i surfed the web and played dota but about 15 mins to the game it happened again! So is this a clear sign of my monitor dying?

I dont but I went to my uncle's place and there everything was okay..even with the usual set up. When i went back home, half an hour into using my PC the problem came back But for some reason the problem seems to be gone for these couple of days
