Hey guys,

I searched google for this and came across a relevant article and I believe the solution might be to get a new pram battery (suggested radioshack), but I'd like to get some second thoughts.

I recently acquired a dual processor 1ghz powermac g4 quicksilver with what seems to be 512mb ram, and an upgraded 200gb harddrive. I had to buy a new power cord from radio shack because it didn't come with one but when I turn it on, i see a glowing white light behind the power button that fades away almost immediately. I hear (and see when i pulled down the side cover) the fan moving, and a little red led light shines bright on the motherboard, but the harddrive does not spin up. I'm not sure if the optical drive turns on either. I tried messing with the jumper settings and switching the ide cables in the computer but nothing worked. I put the drive in an external enclosure and it mounted fine, so i have no doubts on the drive. i replaced the pram battery with a new one i just got, and its still not working. any chances its a logic board, power supply, or motherboard problem? how can i find out

Let me know as i'd love to get working on it.

also, i believe it has two graphics cards and one has an ADC connection - are those the ones that look like dvi but are oval shaped?

Try this: shut it down and press the CUDA button, be careful, I have heard of problems if you press too long:
Resetting Cuda/PMU on Power Mac G5, Power Mac G4, Power Macintosh G3
Pull the drive, pull the ram and restart, it should make a series of beeps when it can't find any ram. Not that this is relevant to your problem but, the QuickSilver could only see 128 gigs of a formatted hard drive. Good luck!

That Mac should have a monitor card with a DVI and ADC connector. The ADC connector looks like this:
