I've got a wireless adaptor in a PC that is not fastened to the case, just pushed in the slot. Reason being if I screw it in the angle is shifted just enough for it not to work and I'm too lazy to jack around with the back plate on a wireless adaptor.
Sometimes reseating the card/cable/RAM is the answer, congrats!
