During startup all I get are vertical lines on my screen?
On my old 2006 Mac pro tower running OS X 7.5, I've rebooted with (Command option r p) twice, yet on startup I'm seeing a bunch of light coloured vertical bars on my screen that appear in front of the apple logo in the centre of the monitor. Perpetually stuck in that mode. Is it the video card that's shot? I've got an appointment tomorrow with "I hope will be a genius" at the Apple store, hope they can fix my sick mac? : (
Yet if anyone can tell me in advance what may be the problem I'd be very graful!
