Theyre updated drivers for your motherboard to improve all round performance and correct any problems and/or errors like you are having.
If you look at your motherboard you should be able to see at least one large chip usally near the battery with VIA written on it, the other one with it on at the top end of the mobo is often covered by cooling fins so you may not see it written there.
If you can tell us which motherboard you have then we can tell you for certain whether it has VIA chips or not
