Hello Stembob, welcome to SF and sorry it took so long. It is very busy here!

6.1.7600.16385 this patch(es) has to do with a usb port/connection. Did you connect / change anything?
Could you fill in System Specs please?

Test if you can boot in Safe Mode? http://www.sevenforums.com/tutorials/69585-safe-mode.html
