Bad Video card or Logic board
First off Thank You! I have read thru a lot of this site and find it great.
My imac is not banding like a see a lot of here be there are colorful patterns all over the screen. I've done the resets. I verified the disk. I'm currently zeroing out the drive and then I'm going to reinstall SL. Then I plan to restart holding D down. Any other suggestions? Thanks! Bob
Is this a good question?
