Having succesfully inserted new memory into our PB1400cs 133 yesterday I tried to clean install the system to cure recent crashing problems. I reinitialised the hard disk and started reloading the system (7.5.3) software but that failed. I did it again and the machine crashed. Then each time I tried to start up from the start up CD it took ~15mins and came up with various problems - e.g. couldn't save the desktop on the startup disk as it was locked, system failure, wrong startup disk etc. At one point I even got the sad Mac message, although I tried again and it didn't reappear. Although I have a PB1400 the original CD player was replaced a couple of months ago so I don't think that's the problem.
Our beloved powerbook is now paralysed - can anyone help??
