I was playing some music on my MBP just now after installing updates and the next thing I know my screen scrambled!!! I re-started and it was fixed. Is this just a one time thing or should I go back to Apple before it's too late? I don't want to deal with them since I already had a few bad experiences with them. My MBP is still within warranty, but it will end in August if I don't get Applecare and right now I don't have money for it. I'm scared.
