Power Mac G5 No Chime Loud Fans on boot

I have a 2008 mac pro that has recently lost its chime as well as its line in and out, and the front usb ports stopped working and then one of the two fixed itself.
Once in a great while, I hear the chime on startup, but the next time it starts, the chime is missing again.
I had to buy a usb external sound card to get back the use of audio on the machine.
I'd say it's probably old age and some motherboard elements are going bad.

Hi All,

I just picked up a 2x 2.0 Power Mac with the issues in the title, was a cheap pickup so why not.

Before I booted the machine I removed the battery and reset.

I then power on:

- Mac chimes
- There is display on monitor, although the picture is garbled. I put this down to a possible heat issue as it looks like the artifacting from overclocking gpu's
- Remove card - Replace thermal paste and thermal pads, reassemble card heatsinks, fan etc. I've done this a good number of times, with many different cards without issues so there is only slim chance of me having damaged the card.


I then replace the card (Geforce 6800 Ultra)

- No chime
- No display
- Loud fans
- Rear optical light is lit continuously

I've ruled out the following:

- Ram is fine - Did not move it since initial boot
- Cover is on - No red leds whatsoever
- Reset CUDA - Done many times
- PSU - Fans power on, board and card are powered

Possibilities:

- Dead battery - can't check, I don't have a meter handy, cant buy one right now its nearly midnight
- Dead card - Fans on card are still running and when it removed and machine is powered on the only change is the fan speed in the case, they have slowed down
- Clean out case - Very dusty, may have cause a failure somewhere bridging something. CBF right now because its nearly midnight here.

Has anyone had the same symptoms? I've read some posts on this but I'd like to go for some basic checks before I go out and spend more money on this.

Does this seem like an issue caused by the battery?

Thanks in advance.

I think that is a warning that the sensor is not tracking that the air deflector is seated properly. There should be some silver label on the peg of the deflector which the sensor tracks. If that is missing then the sensor thinks the air deflector is missing and your Powermac will not boot.

Yes I found out that I forgot to put back the transparent sealing.
Once I did it, ohh the sound of peaceful coolers, the HDD scan and the DSB led is no longer emitting, so that is done, and next thing, is a keyboard, damn that thing is picky one, I have over 20 spare wired keyboards all are logitech brands, but that sucker for some reason like the keyboard which I use daily on my IntelliStation, it likes my Logitech LX-710 Combo Cordless and also it seems to work on key functions, such as pressing F12 it opens DVD drive.

Use a wired keyboard. Older usb keyboards work better. If you use a RF wireless keyboard the Powermac will eject the optical drive on boot up. Call it a feature.

Now that can become a problem, cause all keyboard that I have is mostly USB but early 2007, and the older ones have PS2 jack unfortunately.

2007 is fine. That is plenty old already. People have mentioned having problems using Apple's latest keyboards with Powermacs. Those seem to work fine enough with mine but others may have different experiences.

Well the problem is that none of those early 2007 keyboards doesn't seem to work at all, but as for my wireless keyboard, when I press T it does the action, when I press C button it actually scans DVD drive and then flash drive
 
Well got Radeon x800, Radeon 9600 and Geforce fx5200, let's hope that one of those will actually work on my Power Mac G5

Question, if the hard drive is empty like non formatted, and GPU is installed, does it has to show anything or it will remain black screen?
 
Are those graphics cards PC or Mac versions? Both have different firmware. If you stick a PC card in a Mac you will not get anything but a blank screen.
 
Oh damn I just read through further and my fail, the Mac already needs to have a Panther installed to flash, damned.
