Hi all, when I upgraded from Windows 7 to 10 suddenly the two lower of the four USB ports on the back of my Dell Optiplex 3040 stopped functioning. They worked fine for several years until the upgrade (there were external HDD's connected to them so I knew right away).

Sure, there is the infintesimally small chance they both chose the 4-5 hours the upgrade took to conk out, but how likely is that?

Thank you.
