Lets try DriverMax and see if it will find the drivers for this.
Download DriverMax and have it scan your system. It will open their website with all the out of date drivers you can update. With the free version you can update only 2 drivers per day so if you have a lot of them it will take a few days to get everything updated. I have been using it for about 4 months now and like it better then any other utility out there for keeping my drivers up to date.
If you are unsure which driver to start with then post screenshots of all the drivers DriverMax is saying needs to be updated and I will point you in the right direction on what driver you need to get first.
