problems instaling graphics card

[Kittie]

I am having problems instaling my new card. My computer only has a x8 pcie slot so after finaly finding an adaptor so my card would fit in it it wont work. when I turn the comp on before xp loads up 2 errors pop up,
"pci sysetem error on bus/device/function 0008h"
"pci sysetem error on bus/device/function 0100h"
and it then does nothing.

I took it out and tryed to insall it. a measage pops up saying "maby not leadtek product....."

Also while where on the subject when i start up i get "PCI error press enter to continue" It must be my sound card, yet it works fine. Help!?!?

First, you have to describe your computer brand and model, or your motherboard and memory, then tell us the brand and model of your video graphics card.
