I saw in some post that the issue was the AGP to PCI brigde, in my case
NVIDIA nForce3 250 AGP Host to PCI Bridge. Since i'm using a nForce 3 250
chipset, the nvidia drivers for vista only came with audio and ethernet, no
chipset. So i use the XP driver wich recognized it but still nothing.
This is the forum where is saw that and i know i saw another one talking
about it

"Ok, found out the problem was with my AGP controller. I got it to work
using the XP SP2 mode then reinstalled the ATI drivers.
Now it is working."
If anyone know about this pls
