need windows 7 help please?!

[computerlostk]

I'm going to try to make this sound as less complicated as possible.  I have a hp all-in-one pc that originally came with win 7 pro oa (according to my coa sticker located on the bottom of the computer).  I am currently using win 7 home, and it is giving me some problems such as not loading my integrated webcam and keyboard drivers.  When I go to device manager, I can see the drivers, but the software is nowhere to be found on my computer.  I am also getting "windows 7 not genuine errors" and a black screen b/c my product key is not valid with win 7 home.  I guess my question is, is there any place I can get a valid and real copy of win 7 pro oa (x16-96076) for free and redo my computer using my product key that I already have?

No free locations to get it. Only option I can think of is that if the Windows 7 Pro key is real, you can use someone elses Windows 7 Pro installation disc and then use your key vs theirs to install clean with a genuine key.

It sounds like you bought this system used and inherited problems with the purchase. Its very strange that a system with a genuine 7 pro key would have been installed with a non genuine Windows 7 Home Premium. So I question if the Pro key is any good.

How to Tell if product key is real.

Let me guess.
The owner crashed the system and used  a Windows 7 Home to fix it.
And he did not fell you. 

You will have to find the drivers on the web site of the maker of the computer.
Sad to say, most PC makers no longer include the Windows install DVD.
