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!

Thank in advance and kind regards.
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:
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?
