nvidia drivers bad performance. and act weird

[burned-ati]

ok im not getting my max performance for some reason. well first of all when i go to my settings in nvidia drivers 77.72 it says my video card bus type is pci 0x speed, that sucks its supose to say agp 8x speed and ive noticed im scoring lower in all my benchmarks and im getting lower performance in games. i have tried reinstalling the drivers, and also lookin in my bios to maybe change something. but why would it say pci?

try reverting to previous version drivers

or a different driver

uninstall all the video drivers.
Go into the device manager and unistall your video card
reboot
install the Nvidia drivers after you boot back into windows.
Sounds like a driver conflict to me.
