My laptop seized for about a minute, then the screen went black and was replaced by a field of squares that were each filled with randomly colored pixels. I had to force a power down by holding the button. When it restarted it won’t run WoW but I can run other games. I ran a repair but it still launches to a black screen and the crash message appears.
Edit: I’m off to work so I won’t see any replies for about the next 10 hours. To anyone who responds: Thank you, I’ll try what you suggest and get back to you asap.
