I'm not sure if this is the right website to talk about this, but here it goes.
When playing video games or high quality video for a long period of time, my computer starts to freeze and unfreeze randomly (frozen for 1 second at most). The audio gets distorted and if music is playing, it sometimes sounds like it has been slowed down to half speed or more. If I continue to play/watch, the computer will eventually completely freeze and sometimes bluescreen.
