Pci or agp?

Question

I suspect i have a faulty agp or pci card in my p.c
the computer operates the" CAS Superguide Analyzer" automotive equip.
Anyway, the manufactorer is out of bus. so my question..Is there a place to send the card for testing and correction?
I cant determine on the card who, where or what it is or where its from...
I really need this machine...Have you heard of it? any contacts?
Thanks for anyhelp you may render..
