Okay so last week i get a G4 for my old man its a tower (400mhz processor), anyway i erased and installed tiger all went fine then about 2 days ago after it had been working fine, when you turn it on theres a grey screen (no apple logo and it won't boot anything, cannot get into Open Firmware). i opened it up and took out the cmos battery, then held down the button that completely powers down the logic board. Once i had done this and put the battery back in and hooked it up to the mains voila! it worked but then the next morning the grey screen was back. it seems when you leave it off for a longish amount of time ( 4-6hours+) you get the grey screen but if you just shut it down and started it up or did a restart it's fine. i have replaced the battery on the board but this has not fixed the problem.
