What you probably have to do is get into the Device Manager
tab on the properties for my computer.
You will probably find some entries there that need to be
deleted. They will have either red or yellow icons by them and
will be reported to be missing, disable or some such.
You want to highlight these and delete them one at a time and
reboot.
If you are unfamiliar with configuring windows, you might want to
find somebody to help you take a look at it.
A system backup before playing around with any of this is probably
a good idea also....
Good luck.....
