Ok so a friend of mine got a G5 tower from a co worker and they said they didn't know much about it etc. So we got it home and hooked it up when i press the power button the light comes on but then goes off and i hear a "click" sound . i don't even hear the fans start up just a click sound. i pulled the battery out for 1 hour and put it back in i also pressed the PMU button and same thing so i am asking for help. From what i can see it has 1 gig of ram ( 2x512 ) and its a 2 ghz DP/PCI-X is this thing dead ? thank you viewing!!!
