Changed PC's, now can't get IDE to connect with arduino

Recently changed PC's from an old Windows Vista to a new Windows 10 box. Reloaded the Arduino IDE but I can't seem to connect to my boards now. I've tried two different Uno clones which I believe to be good as well as a Nano cone, brand new out of the package with the same results. Also tried two different cables, so I don't think that's the problem.

Here is the error message:

See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.

This report would have more information with "Show verbose output during compilation" option enabled in File -> Preferences.

In the Tools menu, all the boards show up as connecting to COM1.

When I try the "get board info" tool, it responds "Native serial port, can't obtain info."

When I look at the control panel under "Connected Devices" it says "USB 2.0-Serial Driver is unavailable."

It appears that my PC (or maybe it's just the IDE) is not recognizing my arduinos.

I'd appreciate any guidance anyone can give me.

Clones ?

Maybe try the CH340 drivers that are NOT included with the IDE

Ballscrewbob: Thanks! I think that fixed it!
