1. I am posting this here because Apple discussion forums are down till next week. 2. I have a G4 AGP graphincs, w/384 MB RAM, and what I think is a bad motherboard. I have a 3rd-party LCD display, and a ATi PCI graphics card that drives it. I had been having problems with various cards before, so in order to fix a recurring RAM and MS office problem, I removed the AGP card, leaving just the PCI card. I had just run software update and downloaded the 4.2.8 firmware update. I made sure to follow all necessary precautions, such as grounding myself, and removed the card. I put the computer back together and started up in order to update the firmware. As I did so, I got the tone, and the flashing power button, but the monitor never got a picture (it's happened before). I gave it about a minute to update the firmware, then I reset the the computer. 3. This is where the problems started. First, it had problems recognizing the USB hub that the monitor's USB was on, and so I powered off, opened the computer, re-checked the RAM (in case I bumped it) and booted up again. No dice. Tried to put the AGP card in again. Didn't work. I tried using that button next to the PRAM battery. Nothing. Tried booting from CD. A failure. In a word: HELP!! If I don't get this fixed within an hour (by 4:00 PST) I am SOOO screwed. Please help. EDIT: oh yeah, I got the USB hub to work, but still no picture.
