Half-dead G4

[Justin Hibbits]

Hi folks,

Maybe someone could help me with this problem:  I recently purchased a 1.25GHz 
PowerMac G4 on eBay, and it worked perfectly fine.  However, after loading 
FreeBSD on it, and running it for a couple weeks, it no longer boots.  
HOWEVER, I can still hold down the mouse button and the CD ejects, so I'm 
assuming it must be reaching some part of OpenFirmware, it just doesn't POST 
(I don't hear the chime).  I've tried ripping out a couple RAM sticks, 
reseating the video card, resetting the PMU, and one time I did manage to get 
the chime, without the video card in there, but even pulling the card out 
again I still don't get the chime now.  Is there any other test I can perform 
to narrow down the cause, and fix this problem?

Thanks,

Justin
