I recently got a iMac g5 off the internet listed as "broken". I went on to later discover there were multiple blown capacitors on the board, but it still turned on and got to the no hard drive logo. I had no disks for the iMac, but I recently bought some off craigslist. they are supposedly "iMac G5 Mac OS X Install Disks" and there are two disks, first including OS X tiger 10.4, second including more of the OS X 10.4 install, and apparently OS 9 as well. I went on to insert these into the iMacs disk drive, and it booted to the install process. I selected the language and then went on to the install process. but when I clicked install it said the disk could not be used on my system. I find this odd, as I know the iMac is a G5 (From the huge "G5" logo on the CPU cover) and the disks both say G5 on them. I then went on to erase the hard drive, formatting for Mac OS X Extended (Journaled). then the computer shut off, and would turn back on, and stay on, for more than 5 seconds. I left the computer alone for a few days, and today I tried turning it back on. It successfully booted up (to the no OS logo. (note: I did remove the hard drive and put it back in before i tried turning it back on) I found this very odd, as i have never seen this in any other mac. the iMac has a serial number of: W84510U5PP8. I believe it was manufactured in 2004, due to the lack of and iSight camera. its a 20" model. the disks both say its "disk version 1.02Z691-5493A. and the first disk says its a "AHT version 2.5.1". Am I using the wrong disks? could this be caused by the blown capacitors?
 
Your iMac is the original 20" G5, which shipped with Mac OS X 10.3.5. The install discs you have are for a more recent model. Your best option is to install from a Mac OS X Tiger or Leopard retail install DVD.

It is highly recommended to replace the blown capacitors or else risk damaging the electronics further. It is something you can do yourself (there are plenty of guides online), but it may be better to ask (pay) someone who has some experience with electronics.
