Radeon 9800 doesn't work in new system

[Steven Fisher]

Is there any reason this combination shouldn't work?

Case & PS: Antec Silent White (430 watt)
Motherboard: P5S800-VM (AGP8x)
Videocard: RADEON 9800 Pro

The built-in chipset on this motherboard only gets about 0.2 frames per
second...

No particular reason. What exactly happens when you plug the 9800 in? No
boot at all?

I can see the POST passing, but it locks up forever without getting any
further than that.

Have you plugged a power connector into the 9800?

Yes.

(I really should have mentioned that. It's the obvious first question,
isn't it?)

But, anyway, I think this is a power supply problem. I have other
symptoms of that. I'm just trying to figure out if that's my only
problem -- a technician told me that my mobo wasn't supplying the right
power on the AGP slot, which would have meant I need a new mobo or video
card AND a new power supply.

I would do these in order:

1) Try unplugging and re-connecting everything on your PC, even if you
think it's plugged in correctly.

2) Clear the CMOS. Perhaps you have some dodgy arrangement of BIOS
settings that is affecting boot-up.

3) Try updating the BIOS to the latest version (if it isn't already
there). http://support.asus.com/download/download.aspx?SLanguage=en-us

4) Try the 9800 Pro in another PC.

5) Try the PSU in another PC.

6) Remove the re-seat the motherboard, checking that it isn't being
shorted anywhere.

7) Make yourself a sandwich and admit defeat.

Sometimes symptoms that appear to be a power supply problem are solved
with a BIOS update. Don't rule that one out.

and while your at it disable the built in video card in bios.

This was good advice. Not just the part I quoted. I started with this
step. I'll do steps 1-6 after I finish eating.

The cases I have do not use compatible power supplies, so I had to swap
everything into the microatx case. Skinned my knuckles, too. But the
resulting system works. So it's definitely the power supply in the new case.

Thanks, everyone. Beware the Antec P150!
