I got one of the new mac minis, did a jump to 4GB and installed a 320GB 7200rpm drive. Every couple days I will return to my mini after some downtime (a couple hours or whatever) to a screen that looks like this... ...now it doesnt do it everyday and it seems to be random as to which monitor gets the brokenness. Rebooting the mini (hold down power button) fixes the issue after it reboots. Any ideas maybe its just fubar? Over heating (which i doubt because it never does it when im using it heavily)? Graphic driver? Hardware issue?
