These all sound like devices that could be part of your motherboard; when you bought the computer (or motherbord, if you built it yourself), you should have received a CD containing the motherboard drivers. If you don't have this CD, you will need to open your computer and get the model number of the motherboard. If you can't find the motherboard drivers yourself (using google), you can post the model number here and we'll see if we can assist.
