What is the solution for my display problem? see the pictures!
My son was playing some online games on my iMac 2007 and suddenly it freezes.
I turned it off with the button and when I turned it on again, the display shows some lines. Please help me find a solution for my Mac!
The pictures are shown in the following link: http://www.macusergroup.com.ar/foro/show...
Thank in advance and kind regards.
Alejandra.
UPDATE
You are right, Dan, the external monitor shows the same problem. See the pictures below.
On the other hand, before doing the following, the screen showed lines everywhere and it was impossible to see anything. So I read a post somewhere (don't remember where) that deleting the following files, may solve the problem. So I did it: I deleted the following:
- ATIRadeonX2000.kext
- ATIRadeonX2000GA.PLUGIN
- ATIRadeonX2000GLDRIVER.BUNDLE
- ATIRadeonX2000VADRIVER.BUNDLE
After that, it got better and I could see some lines but the imac is fully working! The first picture shows the Hardware Test I did and it says "no se han detectado problems" ("no problems have been detected). It surprised me because I thought I would find something about damage on the video card!
My question is: is there any possibility that it is a software matter? Could it be possible to try re-installing the video card drivers or something like this? How to do that?
Thank you very much again for you great help!
Is this a good question?

Sorry, No its not a software issue. While altering the drivers may appear to make it better it does not fix the root issue here.

The question still is: Is it a heat issue or a bad card? If the system does better in a cool room when you start it up (after cooling down) then its a heat issue which maybe fixable with cleaning and re-applying the thermal paste and cleaning out the dust within the system. IF it makes no difference then the graphics card is gone.

Ok, thank you very much again for all your answers. They were all VERY useful. Evidently it is not a thermal issue as I turned on the iMac after a lot of days. And my question is still: what caused the problem? was the game Crash Car 2 that my little son was playing on line?
