Apple iMac G5/1.9 17-Inch (iSight) Specs
Identifiers: iSight - MA063LL/A - PowerMac12,1 - A1144 - 2081
In general your machine did not have the bad caps problem, although I have found some in this model on the back side of the logic board.
I would call Apple up an order the original system installation disk for $15. This will allow you to run diagnostics, install a system and have access to Disk Utility to check the hard drive. This machine has diagnostic lights to the right of the RAM slot but you have to remove the frame to get to them. But first try reseating the RAM one stick at a time, attempting restart with each change. After you have the frame off, look at the diagnostic lights and then start up noting any changes in the lights and let us know. Thanks
Note: there is probably a piece of black tape covering these lights, just remove it.
Mayer is 100% correct. The iMac g5 iSight models were 1.9 and 2.1 ghz and used ATI graphics cards, not NVIDIA cards.
A few trouble shooting tips I can give would be these:
1. boot the machine, and hold down the option key. Do you get to the boot manager and see a mouse? This test is important because if you see the mouse, it means you have video information.
2. remove and re-seat the ram, one stick at a time. So for instance, remove both simm's and replace just one then boot. Is there a change?
3. As Mayer described, get the original disc's from apple, or visit an apple store with the machine and have them boot it to an OS and see if they machine you have even has an OS on it. I've seen people just wipe drives before they get rid of the machine, so you may just need to format the drive and image it with an OS.
