Hey guys, I've been following a few G4 Cubes for a while now and just haven't been able to justify the ridiculously high prices they're going for. However, I've been watching this one for a while and and have been hoping that it could be salvageable. The machine boots up and chimes, but then proceeds to a completely blank, white screen - as opposed to a sad Mac, flashing folder etc. I've never come across a Mac that's thrown up a blank white screen before - do any of you know what the issue could be? Thanks.
