Powermac G5 video problems
Hello,
I have a Powermac G5 Dual processor 2 GHz; I believe it’s the first generation G5 Model.
I got this mac 2 weeks ago, I was told that the video card was probably broken, it seemed to be, no display when turned on.
As a stopgap I used an old PCI Rage card from a B&W G3 and it happily booted from that, as you can imagine the performance was a bit grim but it worked.
I've managed to source an NVidia 5200 AGP card for it but when I put it in the AGP slot and boot it bongs and the fans start normally but the display remains blank, basically exactly the same as the ATI 9600 it came with. If I leave the machine on the fans gradually increase in speed. Pressing the power switch for 5 seconds turns it off
I’ve tried resetting the PMU and tried resetting the Pram but, it seems to not boot to the stage where the keyboard is recognised so it does not reset.
Thinking the new card was also duff I put back in the old PCI card but the machine does exactly the same now as it does with the AGP cards.
I’ve left the machine now unplugged from the wall with the battery removed.
Any ideas what is going on??
Thanks!
