I've seen the DriverPack "Delusion" before but had to frown on it Since XP even I have had any need for anything along those lines as far as getting the correct drivers installed either by disk, Windows updates, or a trip to the support site.

You may want to shut everything and carefully pull the video card out and blast the slot for that out as well. Then carefully but firmly reseat the card back in. If your card hasb't gone toast which will generally stall a system anyways as well as sound off it may have lifted up in the slot explaining why you are not seeing anything.
