Intel Chipset & Realtek HD Audio update & simple check

Intel Chipset & Realtek HD Audio update & simple check by DELL-Chris M

I do this once a quarter on my Alienware X51-R1 to stay current.

Intel Chipset update
Run this easy to use Intel Driver Update Utility and it will automatically tell you if you need to update your chipset INF file, and if so, will prompt you to install. Once installed, Click Start- Intel Driver Update Utility- Intel Driver Update Utility 2.0. Then click "Auto detect...".

Once you have done the above Intel Chipset update and restarted the computer, proceed to the Realtek installation below.
