My Dimension 8200 restarted after install ed a fire wire card and then came up with the following error immediately after the title screen upon boot up:

Plug & Play Configuration Error
Plug & Play Configuration Error
Plug & Play Configuration Error
Plug & Play Configuration Error

Windows XP defaulted the video driver back to a basic, non-plug&play driver that can only support 4-bit, 640x480 resolution.

Windows XP apparently cannot recognize the video card, network card and all pci and apg device.
I have also tried manually reinstalling the video driver (NVIDIA GeoForce2 Ultra with 64MB RAM.)

i Disconnected all peripherals except for keyboard, mouse, and monitor. this worked. After restarting, the video problem was gone. everyting is ok.

 

when any pci card is istalled in any pci connector, the problem come again

 

Any help is much appreciated.
