Q: Power Mac G5 won't boot. Black Screen, No Chime

Hello,

 

I've had a Power Mac G5 for a year now. I stopped using it for a half a year and decided it was time to boot it up.  It was working fine until this morning.

I booted it up as usual, and first time there was a chime, loud fan noises, but no video.

I opened it up, replaced the battery, reset the smu, and took the ram out and put it back in.

 

I have tried the classic boot up commands such as.

"command, option, p, r" - doesn't work.

"command, option - no response.

 

After this I tried to boot it up again.

This time there was loud fan noises, a VERY unusual screeching sound (sounds like it coming from the speaker??), no chime, and no video.

 

Please watch my youtube video. Showing the boot up progress:

Can someone please help! I have no idea what's wrong. It was working perfectly until today!?

PowerMac, Mac OS X (10.5.8), No display No video
