Hi guys, I take it you are all familiar with this irritating message : You need to restart your computer. Hold down the Power button ... or press the Restart button. Here's the situation : I was watching my favorite Sitcom when all of a sudden, the screen went flaky (I could still make out what was on the screen though) and the computer froze. I forced it to shutdown. When I restarted it, I saw the usual Apple Logo with the loading circle underneath, but they too were a bit flaky. There are wave-like distorted flaky grey lines above the apple, and the loading circle isn't crisp either. Then after a few seconds, the same message appears : Not the classical grey screen with the 4 language "You need to " ... message. It's grey, with flaky black stripes. So I've been through it all : Zap the PR ram or whatever, change the RAM, etc. It won't even let me boot from a CD. I inserted the Install CD1, and held down the C key for it to boot from the CD : nothing, it boots as if nothing happened. Then, I restarted holding down the "Alt" key, specifically selected the CD drive, and then again nothing. The apple logo shows, and then the error screen. What can it be ? From what I've read, this must be a hardware issue since it won't let me boot from a CD and since there are those flakes, I take it my graphic card is fried. Can you confirm this, or is there another explanation ?
