I recently bought a Power Mac G5 with no OS X running on it. When i first power the machine it gave me a white cream with some question mark of that sought. So i realised there was nothing like OS X on it. Now i want to run the OS X and when i put in on it blinks 3 time and repeat it at evenly intervals. please even though am new to Mac Machines i know there must be something wrong. Can some one give me a straight answer to my problem. Thank you
PowerMac
Hello,
Older meanings...
Can you count the beeps or flashes?
1 beep = no RAM installed
2 beeps = incompatible RAM types
3 beeps = no good banks
4 beeps = no good boot images in the boot ROM (and/or bad sys config block)
5 beeps = processor is not usable
In addition to the beeps, on some computers the power LED will flash a corresponding number of times plus one. The LED will repeat the sequence after approximately a 5-second pause. The tones are only played once.
Note: In this case, a flash is considered to be 1/4 second or 250 ms or greater in length.

If you're sure the RAM is good, try the Hair Dryer trick...

No power light at all...

It can show on any G5, and even many other computers & electronic devices of the period.
