user45739: My lab partner and I are working on a project for school and we are using an Arduino Mega 2560 for prototyping. The board was working just fine until, out of nowhere, the board was not being recognized at all. I tried reinstalling the IDE but still it does not work. I checked to see if the Arduino driver was installed, but the board does not show up in the device manager. Also, the L LED on the board does not light up at all. Attached are photos to help understand the problem.


If someone could help, it would be much appreciated. Thanks.

user45940: hey i had the same problem, i am thinking because i installed atmel studio and then this started happening, 
I then downloaded arduino from the microsoft store,(no change)
then i restarted the pc, now its compiling and uploaded normally but still does not show the name of the board that is connected just shows lets say just  COM22 with out saying what board
