|is this a windows 7 upgrade or did it come pre-installed?|
You also didn't say the brand of your Laptop.
If it is an upgrade or fresh install of windows 7, then go to the laptop website and download the latest driver (from the OLD operating system) to your desktop. Then right click on install as administrator and see if that works. If not, then right click on it once again and click on compatability mode, it will start up and then you can try to install the drivers again. It should work this time.
If windows 7 came on your PC, then tap f8 on bootup and then click on Repair my Computer
