Harry, if you don't mind me saying I wouldn't worry about testing your drivers. You have two or three key drivers - video, audio and nic (if you use a nic). If everything is working properly you should not update drivers. The only time to update a driver is if you need certain functionality that is offered in a new release (including compatibility with an OS update) or if you are having a problem with your current driver. IMO, updating drivers needlessly causes more problems than anything except malware. There is really no such thing as an "out of date" driver.
