Hello and welcome to the forum.
My first suggestion would be to go here

Confirm that the Revision number is identical to your board and then check to see if there is a BIOS update newer than the current one your board is using.
Second.... same place.... select your OS and architecture (32 or 64 bit) and download and install the latest Chipset driver and well as anything having to do with Intel Rapid Storage Technology (which requires .NET 4.5)
The audio and video drivers would be icing on the cake, they both look reasonably new.
