iMac is making a ticking sound and shows dead pixels
I have this ticking sound over 1,5 years. It's in the above left corner. I think.
See Youtube to hear it!
After artifacs in windows with text and outside buildup, looping horizontal line i've got now only deadpixels with Youtube or Quicktime video's.
Many time I get a beach ball the iMac hangs.
What can this mean?
Bring it in twice to an Apple Service Provider. Answer: there is nothing wrong!
