So I recently purchased a used Dual 2.0 G5.. it had a fresh install of Tiger on it. The first thing I did was update software to 10.4.11.. however after prompted to restart, the computer will not. It powers up, but nothing is displayed on the screen. After a couple mins, the fans speed up to maximum (or what I think is maximum) speed but still nothing. Couple questions... 1. Anyone experience this before? 2. Since I can not get anything on the screen, how can boot off of the cd to reinstall Tiger, since that seems to be the problem. 3. How do you insert a cd in to the optical drive on a powermac Thanks for your help and patience..
