How do I pin point a start up issue?

Hi, I was sold a really bad g4 power book and now I want to see if I can fix it. It seem like the seller just put a bunch of failing parts in a 01 g4 and lied and said it was a 03. Anyway here is a list of issues

The fan is not working

The cdrom wont read any cds just ejects the after a few moments

The battery does not old a good charge

The screen is getting dimmer

It only boots to the flashing question mark folder

will boot open firmware and option menu but no other commands.

I need to hit the little reset button in the back each time I want to turn it on, it will boot and chime but if I don't hit that lil button there will be no display on the screen

The seller lied and said it had a 40 gb hard drive but it only has a 10 gb drive and it is not held in place by anything. Also its not the original HDD that came with this g4 as the battery panel sticker says it came with a 20 gb HDD.

How can I tell if its the logic board, pmu, pram battery, inverter board or what ever that is causing multiple component issues or if the thing is just full of bad parts?

If at all possible I would return this to the seller and get my money back. Failing in that the first thing to do is to try a OS disk and see if you can boot to it. I am guessing there is no OS on the hard drive being the reason for the flashing?. You will need to find hard drive mounting parts and I would think a larger hard drive (20GB should be good for this unit) and possibly a optical drive. You are going to need a copy of the OS for sure--not newer than Tiger I think. (Depends on the speed of your processor and installed memory) I am going to include a link to the repair guide to help you. The fan could be a loose connection or may need to be replaced also. Good luck.
