Fitting an additional sound card is easy. It will slot into a PCI slot on your motherboard - you can buy the cheapest one you can find. PC World do one for £17.99 - PC Line SC5100. It has 5.1 sound and all the connectors you need. Just remember to touch the case of your PC before you unpack it and slot it in (to get rid of the static in your hands).....and you'll find the PCI slots towards the bottom of the motherboard and they'll be white. If installation of a driver is required then it'll be on a CD incuded with the card. Fit the card into your computer first and then use the hardware wizard in the control panel to install the driver. It;s as easy as that.
