How do I delete Vertical color stripes (pink-red-green) on desktop screen - 6 of them. Anybody have the same problem? Other Mac groups have same problem.

How do I delete vertical color stripes on my destop screen. There are 6 of them in pink, red and green. Can't believe I'm having problems with my wonderful iMac!

Unfortunately, they aren't something to be "deleted." Might be a hardware/graphics chip problem. You should run the Hardware Test in Extended. Might have to run it several times to pick up an error.
