Q: Sudden Grey Screen And Shutdown

Ive been using my mac for gaming and for school work. I share an account with my mom and sometimes when i'm playing or watching a video the screen randomly turns a solid grey color. It first started when I was playing a modded form of Minecraft. I was in a Skype call with friends and suddenly the screen turned blue. Sound was still playing and i could talk to my friends through Skype. The keyboard did not send any signals to the mac so I had to pull the power cord. Upon plugging in the mac everything seems fine. It acts as if i just logged out. I played for a little bit longer and now the screen turned into a solid grey color. This has now been repeated a few time before the computer automatically restarts as if there was a power failure. I don't know whats happening but the mac is not in its 1 year warranty and I cant find any other similar stories. Please someone help fix this problem.
