Hiyya Jarrod and welcome Mate I am a bit confused too what exactly do you mean by your audio service?
In the meantime I found this via a Google - take a look at 714's answer. The Audio Service Is Not Running + No Devices Found
In case you want to find that type msconfig in the Start window and it will come up as a small blue window - run as admin (I always right click and add to start menu for quick access) in this screen you can also set what you wnat to boot - see the tutorilal by Brink on optimising windows 7 Optimize Windows 7
=Performance Maintenance < very handy to get your machine running at least 20 - 25% faster if you don't mind losing transparenct etc.
