So my computer has been randomly locking up while playing games and will just freeze. I manually restart and sometimes won't happen for a week or will happen before it even loads all the way back up. Sometimes if freezes whatever is on the screen when I'm playing a game and other times it will crash and go to a pink screen, green screen with lines on it, or a grey and baby blue screen. It is always random so I can't go recreate the crash after trying different solutions. Just recently it has got a lot worse to the point where I couldn't get the computer to boot up all the way without crashing. I stopped trying after a few times and the computer just shut off while booting up and the power supply fan went full rpm and just stayed on until I hit the power button. What's going on?
