SanDisk Ultra USB 3.0 not visible AT ALL

I have a Windows 10 OS and my usb has always worked fine with it. Couple days ago I uploaded a lot of video files onto my usb till there was about 2gb left out of 16gb. The morning after my usb is not visible AT ALL when I insert it. There’s no lights or sound or any notification at all it is plugged in. It doesn’t show on my computer. It’s not showing any thing. Please help, I need those video files for a work placement.
