G5/Flashing power light

[smiffy07]

Hi
I need a 2nd opinion. I just tried booting up my Dual 2.7ghz G5, the fans span a little but all I get is the power light flashing twice every 3 seconds.

I had a quick look over the net but all I get really work out is that it may be a problem with the PSU.

Any ideas?........

Try reseating your memory. Have you recently added new memory to your Mac?

Hi
Thanks for the heads up, worked it out in the end. I took all the ram out and didn't put it back in the machine in the correct sequence!
Silly error!!!
