So yesterday I was playing Dota 2 as usual when suddenly, artifacts, followed by a screen filled by red lines. Reboot, 2 lines of red artifacts on either side of the screen. When the windows loading screen finishes, screen stays black and loses response (have to hold in the power button for 5 sec for it to shutdown). Now, an hour ago I saw some lines and mixed up grey crap on my screen while on desktop (using intel HD graphics 4600) with the graphic card removed and packed for the RMA.

Any guidance?
