G5 Will Not Bootup...

Hi ive got a Dual 2Ghz G5 with 1Gb RAM, ive had it since december and has been running Logic 7 sweet. However i go to turn it on the other day and it will not boot up. I hear the chime noise and the fans start to run. But no display comes up at all. I have tried the apple help site and have tried restetting the PMU but it hasnt helped. The mouse lights up as normal, so i presume the keyboard is getting power as the mouse is USB'ed off it. So just to test its not the monitor for sure, i waited a while incase it was booting up with out displaying. I then pressed the eject on the keyboard to try and open the DVD, but nothing happened. The only other thing is if i leave it running for a few minutes the fans get faster and faster and sound like its not going to stop, so i power it down by holding the power button.

Any help would be grateful!

Audio Playback Problem

Ive got Duel 2Gz G5 machine with the Delta 66 sound card. Im having problems playing back audio. It seems to play fine for a few seconds, then be it in logic or itunes, it stops and starts a few times, returns to normal, then does it all over again. Its almost like its a hard drive problem, but im not sure. Any sugestions?
