USB Totally Undetectable

[SanDisk Cruzer Pop Problem]

Hi,
I have a SanDisk Cruzer Pop 16GB. It's done it before and that was when I just reinstalled the stuff I need to do and whatever... But that's not the problem, it's doing it again, I put my usb into a port on my laptop, and the ding dong or sound that it usually makes when i insert it does not 'sound'. I already looked at Computer>Manage>Disk Manage and for Disk 1, and it's just not THERE. I have a mouse that has nano reciever usb and that 'sounds' and mouse works and all but my usb just CANT.

I have really important work in that USB and I need to use it quick because there are things I need to do.

I would try the USB stick in another PC, as inconvenient as this may be. If your USB Ports are detecting other hardware like a mouse, then the problem 'shouldn't be with the laptop.
