My friend just bought a new HP burner (he owns a HP) and after he installed it, his computer didn’t recognize any sound devices. The computer has no sound at all. Multimedia properties in the AUDIO tab is all grayed out. I heard something about “ATI”. . .could this be it? Oh and the modem, that is not recognized either.
He also installed new RAM, boosted up to 256 could this be the problem?
