So for the first time in over a year since I purchased it, my iMac crashed twice. The first time was this morning, i went to do something and the screen went black, and my secondary display got black and white lines. I had to restart. And the boot screen with the apple logo hung around for a while. Then, later on the screen went whacky after trying to wake it from sleep (not full sleep just display sleep) and had a bunch of moving lines and then I couldn't see anything. So luckily I got a picture. After restart, it seems fine. I'll call apple care in the morning, but thought i'd try my luck here. Any help would be appreciated.
