It could be that it just isnt getting enough from the agp slot regardless
of
the molex connector?

This is a likely condition. Only MBM will tell for sure.

Is there a setting in the bios to up the agp voltage?

This is a KT133A chipset, obsolete and old. In that order. It is possible
upping the AGP voltage would overcome the resistance of a weak trace, or
failing component.


Tried running the pc with no usb devices, 1xcd, 1xhd and no other pci
devices?

I suspect the 5900 is simply too much for the KT133 chipset and the AGP slot
attacted to it. New mobo req. Agreed?
