MAC Crazy

Q: Light blinks 3 times on startup for Power Mac G5 (June 2004)

The MAC froze then the fans went crazy, so I held the power button down to shut it off.  After pressing the button to start it up, the light at the power button began to blink 3 times and a red light inside the MAC stayed on.  I have (4) 1gb memory sticks and I have taken them out in pairs to see if this resolves the problem. No.  I even put the memory that came with the MAC back in, didn't help.  I took all memory out and got 1 blink.

What does the 3 blinks mean?

If it is memory, how can 6 sticks of RAM be bad?
