What I would do is find a Win7 installer for your version with SP1 to clean reinstall which will likely take less time than troubleshooting this issue: Reinstalling Windows 7

Until then you can study the logs and use System Resources to look for repeat errors and problems reported which may figure in: troubleshooting steps

I'm not sure why this is posted in Installation & Setup when the issue is best dealt with in Updates forum where those experts likely know about this.

Yea, I already did a reinstall. Got fed up with it.
