Clip+ won't open using Windows 7

My laptop is just two weeks old so I dont think it’s a hardware problem or even a software problem (corrupted os issues, viruses, etc).

All of my USB ports are working fine, I tried the three ports with my usb modem, usb mouse, game pad, 3 flash drives so I dont think it’s also a USB port problem. I have also tried 3 different USB cables,

There is nothing wrong with the Sansa itself because it’s working fine on my brother’s computer.

When I plug in my player, it only charges. No notifications whatsoever. Not even in the Device Manager screen.
