2010 Freezes on launch

I had an interesting call recently where the program would lock up after launching it. We'd get as far as the drawing window and sometimes the ribbon would show, sometimes it wouldn't. No icons (osnap, workspace, etc) anywhere on the screen or Ribbon most of the time. It required an end task to stop 2010.

We tried all the usual suspects, video first because this type of behavior smacks of video. However, it wasn't video. I was told he would format and re-image the machine as a last resort and we were almost at that point. Then I remembered, Autodesk told me a while back that the Ribbon icons are heavily dependent on the .NET Framework, so using the Add/Remove Programs feature in Control Panel, we did a repair on .NET Framework 3.5 sp 1, rebooted and it worked!

Autodesk programs rely heavily on your graphics card and .NET Framework.
