Hmm, the woman at the tech-center said she new for sure it was the vid-card when we told her about the screen doin tha squeezy thing.
And I managed to get all the necessary files off of the computer by pressing the PMU reset button on the logic board. It let the computer run long enough to burn a couple CD's of data, but then it flickered and shut off again. And everytime I press the PMU reset button, the computer stays on for around 10-15 minutes at a time. Whereas when I didn't press it, it would shut off right after start-up
But we're taking it up to get the video card replaced and the battery replaced and everything checked out tomorrow. That means I'll get my iMac back for the weekend!
So hopefully, it IS the vid card and it can be easily replaced and there will never be more troubles with it ever again. :rolleyes: I'll keep everyone posted
