G5 Power Mac Dual 2.3 running 10.4.11 with 8 GB ram. Forgive my not searching the forums for similar threads, but I'm in a pretty bad situation. I was cutting in FCP, playing the timeline which consisted only of a piece of music, and all of a sudden it stared "skipping", like a CD that was stuck. The program froze, and I couldn't move the mouse to get back to Finder and Force Quit. I decided to manually shut down with the front power button. The display power light remained on, and after a minute or so I tried powering back up. I got nada. The tower turned on, but nothing comes up on either of my two displays. I manually shut down power again, and unplugged the display and re-powered up once more. Still nada. Both are on, but nothing appears on either display, and the fan is running very high. The power light on the front of the tower is blinking a repeated sequence of three. Somebody please tell me I'm not royally screwed. *Update: I removed and reinstalled all of my RAM sticks. I think one or more of them weren't completely seated correctly. I'm thinking they were always this way, and eventually were jostled loose enough to cause the problem.
