Windows 7 x64 Update not working

On march 6 2011 suddenly it stopped working. It is stuck on KB32483614 and KB82479943 with error 80070643 and several other errors. It says 'failed' at the end of the install process for every update. I contacted Microsoft by email and tried everything they have suggested. Clean boot does nothing. I have removed every program that was installed on the dates prior to this problem.
Also, when i try to install AMD overdrived i get error 1935. AND Windows Live photo Gallery errors and crashes.. I can pull up Pictures but i can't view files except by drag and drop on Google Chrome.
My son says to reinstall Windows. Please Help Soon!!
