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!?
