I have the same problem as you, so if you sort it please let me know. what i would suggest is that you use the drivers that came with the hardware and not window xp as there crap. You will have to uninstall the hardware and drivers and then reinsall. i have have tried everything myself, all the trouble shooting and speaking to techs. but nothing, and i have an onboard card. The only way i can open my PC is with a HAMMER as it does not have screws. i feel screwed, a brand new pile of junk is what i have. so please dont forget little old me when you get your PC sorted.
