Did more tests, would not boot, on any cds, would not firewire mode, nothing. Very bizzare. I ended up opening up the case, and carefully removing all ram, pci-x cards, agp card. I then carefully put each back in, booted, and POOF it worked fine. Perhaps the computer just had gremlins in it... or something was just barely loose. Who knows.... what a scare!
yep.

Does the new silencer add any weight to the video card? This might affect things.

Altair... It does add a significant amount of weight. I don't recall the figure, but I read on a review sight somewhere that in almost increases the graphics card's weight by about 50% or more.

Last night I took everything out of the g5, ram, card, other pci-cards, etc... dusted her out, and reset the FPU, then put it all (carefully) back in. Reset the PRAM on first boot, and it worked!! My guess is that there was an incomplete connection somewhere, maybe because of the weight even? But things are well now... Thanks!
yep.

Wow, that was lucky. I had a similar thing happen recently with some very hard to replace gear. Gave me the shock of my life. But opened it up, check the connections, and tried again and it worked. I have no idea what it was.

Probably the graphics card was not seated properly.
