Ok, Download this utillity and run it. It will tell you exactly what your motherboard specs are for the
integrated sound ,video, and networking.
Write down what it says they are and then go to:
register(no spam) and then look for the drivers that match what you have.
Download them to the desktop. then open them and install them one at a time rebooting between each install. The drivers from there are self extracting so should install without issue.
