One day I came down to find only a colorful, diagonally striped screen. I unplugged and rebooted to a jiggly mess that froze after a minute. I did the same routine, and it booted fine, but when the screensaver came on it went diagonal again.
I rebooted, turned off the desktop pix and screen saver and it was better for a while. Then, it did the same old trick after sleeping. Rebooted and turned off sleep.
I also turned off Classic startup, after rebuilding the desktop.
Everything was good for a few days, but it just went diagonal again.
Am I facing a hard drive meltdown or what? It could be some sort of corruption, but where?
I’m going to take it into the Apple Store next week, but I’d like to look less like and ID10T when I get there.
