Q: So what does LED #3 and #4 tell you?  My iMac G5 does not POST but LED #1 and #2 are on.

Very frustrating.  My iMac G5 that has ran well for the last 6 years now suddenly refuses to boot.  No chime, no resetting PRAM or SMU helps.  What gives?  Did Apple build in a self-destruct timer to get me to toss this thing and buy another one?  Pleeze help.
