About a week ago I started gettin USB Deice Not Recognized.  it constantly show up in the lower right until I click on it.

There a lot of USB drivers from things I've plugged in.

Did some research online and figured I'd go to Device Manager and delete USB devices that were no longer applicapable. 

System Manager constantly refreshes.

Tried to do a System Restore to previous point in time.  They didn't restore properly.

Any suggestions?
