Go to the Motherboard Manufacturer's WEBSITE and DOWNLOAD the drivers. They're FREE. Open the Computer, Look at the Motherboard, Determine who made it, find the Model Number of the Board (It will probably be right on the board it's self in BIG LETTERS), Go to the Website, and download all the drivers.
There's no reason to make it hard. It's NOT. All it takes, is a little effort on your end. Either that or you can pay the 40 Pounds to have someone do the Half Hour of work FOR YOU. My Suggestion: Do the one that's Free.
