So I've had this computer for over 2 years and everything's ran fine until the other day, now every time I launch a game, both my monitors seem to turn off and the fan speed goes to max and I'm forced to restart. I can even still hear skype or a video I was watching when it shuts off, but the game itself seems to freeze and I can hear it stutter. I bought a new psu and it does the same thing with that one, I've cleaned my graphics card and the heat sink of dust, not sure what to do next. Any thoughts for this problem?
