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?
