Greetings all, I'd like to seek advice for those who've tread down the path I need to take. A while back I donated a G5 tower (June 2004 model, 1.8GHz DP w/ PCI slots) to a small private school. Recently I was told by the teacher that it just stopped working, so I took it in and ascertained that the video card was the most likely culprit (issue= boot up chime, then nothing-nothing fires up, except the fans going full tilt if you wait a couple minutes, then you need to do a hard shutdown). Apparently not, as a replacement card (known good) and a 2nd used one I had failed to remedy the situation. Re-seating RAM, pulling 3rd party cards, new PRAM battery, returning unit to OEM status, and resetting the board all proved fruitless. So, I'm inquiring from those in the know what the next step is. Alas, all keystroke related remedies (resetting PRAM, NVRAM, single user and verbose mode, C key for optical, etc.) are not an option - the boot-up mode does not get far enough in to query the peripherals or seek an OS. I fear it may be bad processor or logic board, but maybe there's a way to verify or get around? Many thanks for any input.
