Ok so I brought this laptop today with OCLP already installed. I was in the middle of googling stuff and then the screen just all of sudden did this, with the mouse locking up too. I turned off the laptop and then tried to start up and login in. I get to the point of signing it with password and it starts to load a quarter of the way then it starts glitching and freezing again. Is there anyway to fix this or is this laptop done for?
