IMac screen gets distorted (see image). sometimes it fixes itself, but it happens very often (every 30 min or more),.
the computer is not even a year old.
i have had a few different Mac computers and never had this problem before.
is this something I can fix myself?
Mine is doing something very similar now. I managed to do the Apple Hardware test and it came up with the Error Code 2 FAN/5/7: Hard Drive. This leads me to believe that the problem is the fan by the hard drive. Your problem may be the same thing. If so, it's just a matter of finding the part and the installation instructions (on the Apple web site).
Try the Apple Hardware Test from the Mac Os Software that came with the computer. You install Disc 3 and shut down the computer. Then turn it on and right away press C on your computer. This action will take you to the Hardware test. Press one of the buttons that does the test and see what results you get.
If you get the same error code you might want to check out welovemacs.com for the fan.
