My MKR1000 wont let files be uploaded to it, please help!

My issue is that when I plug my board into my computer is that the MKR1000 board will not show up in device manager, the 'on' LED is switched on, I go to the Arduino software and check if I still upload projects to my board. It doesn't work. I tried all the mentioned solutions, I'll make a list :

-The new hardware sound does not come when I plug it in.

-I've tried using three different cables off them are 2 data cables and 1 power cable.

-I only have USB 2.0 on my laptop.

-I tried it on other devices(two, both running windows 10).

-Also I tried to send the CPU into bootloader mode but that didn't show anything
