Hey! I have had something like that happen to me. Directly after I installed Leopard (upgrade install) on my G4 Sawtooth AGP, the gray screen came up for around nine seconds and then...zapp! The drive had to be wiped clean in the end. I arranged the components in all sorts of configurations, took out questionable RAM, swapped monitors(ADC)....everything. I couldn't boot from the D drive which made things worse. Disk Utility via laptop helped out with that. I hope that you get your answer.
