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.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

Do a power drain, this may cause by an electrical charge in the motherboard itself,Im Not really sure how it affects the display of the computer but this method usually fix such problem like that, First, removed the battery then unplugged the AC adapter the press and hold the power button or the ON/OFF button for at least 30 seconds then connect the power supply back to your computer then turn it back on, if nothing happens, there is a possibility that the problem is with the LCD or monitor itself, maybe it will need a replacement...
Hope this will help...Your response is very much appreciated...
same thing happens to me - most of the time it will just randomly freeze; occasionally i get an unresponsive black screen. this 24' aluminum imac usually has startup problems also - sometimes it will "gong" and nothing else; sometimes the apple logo will come up and then nothing else; sometimes it will load the logo and then spin for a few seconds and then freeze - the only option is to manually shut down. there is no rhyme or reason to it
Hi, Sorry you are having problems,
OK, so, all macs have internal batteries. When a Mac has been unplugged for a long time, the battery empties and makes the first few bootups pretty rough.
One answer I can give you right now is that this iMac is not work more than $150 in the second hand market. Although it is a beautiful machine, I don't recommend inverting any money in it.
Unfortunately, if you had waited a little longer, say like 30 minutes, your mac might well have booted up properly.
Have you had it unplugged now for a couple of hours?
Try it again and let it run.
But, if it does not work, chances are that something blew, probably the mother board.
