I have a B&W g3 that has been upgraded to a 600mhz G4. It has been workin g well for several years now. Yesterday I booted into OS X 10.4.11 and it had a kernel panic. I tried restarting to no avail. Everything powers on, the fans the optical drive and the hddrives. The power button is green but there is no chime and the screen is black. There is no power to the USB ports so I can't use the keyboard to flash PRAM or boot into open firmware. I've tried the CUDA and taking out the battery. Any other suggestions would be appreciated.
