Right. I remember having a problem with my iMac screen similar to this during bootup. It may be your graphics card or screen. sorry to say. is that picture of it a screenshot? if it is then its a software issue.if not then try it.

Come to think of it. have you uninstalled that screensaver. and it sounds like a .plist error. try trashing some of them. such as finder...

Try Tech Tool?

God im a geek :P

It should be no problem, I have done it a couple of times. Just make sure you only press it once as per the instructions. If you don't feel comfortable doing it yourself look around for an Apple authorised repair centre or Apple store in your area and take it there.

thanks, for the notes. It cant be .plist error nor software as I have erased the disc and installed a new OS aswell.

I think it must be the monitor (Apple Studio Display), so will know once I borrow another this weekend. I went into an Apple store and spoke to a 'Mac Genius' he has since emailed me back saying he is going to look into it. So lets see what he comes up with.

I've tried the pmu reset too Tommo, but yet the little buggers are still here.

i will post if I have any progress. Cheers for the help.

p.s. ive just nticed the screenshot is only really visible if you open with Photoshop not Preview. doh!

Cheers.

It sounds like it might be a video card problem. If you still have applecare try to get it fixed. If not it may cost a fair bit.

chance is just re-seeting you videocard could help.
and are you sure it's that screen-saver? i've had some issues with old cards that seem just related to tired capacitors..

at the same time, i screwed-up the video-card of my old powerbook once just by writing bad openGL code.. but that was gone after a reboot:
