Setting up an ATI Radeon x1600 AGP graphics card in Vista

Hi all,

Currently trying to set up an ATI Radeon x1600 AGP graphics card with 512 MB
video memory in a clean Vista Home Premium install.

The error code I'm getting after the BSOD is STOP 0x000000EA

I've gathered this issue is not uncommon when trying to pair this card with
Vista for the first time. To complete the install, I had to swap back to an
X800 AGP card.

The cards both run vista, but neither card had been recognized in the device
manager. (checking display properties showed the system was running VGA safe
drivers instead of the installed catalyst drivers).

I suspect part of my problem was installing the pci-agp drivers included
with my motherboard. Uninstalling them brought me back to the BSOD and error
message. I'll try swapping back to the x800 card and getting catalyst up and
running before swapping in the x1600.

I've also heard that Vista takes a lot more juice to run the x1600, even
though it ran fine on xp. Would I be better off going with a more powerful
power supply? Any other suggestions I haven't tried?
