HELP! usb 3.0 not working!

hey guys, i just bought a new computer

and im using

motherboard: Gigabyte 880gm -usb3L rev 3.1

it has 2 usb 3.0 slots, plus the x3 usb power feature…

and i bought a WD passport essential SE

1TB and features usb 3.0/2.0 compatibility

its half full btw, close to 500gb of space used.

i have it set to NTFS ( for both mac and pc)

when i plug it on the usb 2.0, it works fine, transfers files pretty good… ( on any computer)

but when i plug it on my new usb 3.0 slots, nothing happens… but the small white light’s on…

note: updated the usb3.0 driver and WD device already…

any help?

also i

If the drive is NTFS, are you testing the USB 3.0 on the Mac? Are you able to use the drive on Mac with USB 2.0? What about the Windows Computer, Does the drive work there with USB 2.0 or 3.0?

i formated it to NTFS from my mac book pro, ( my mac book can read/format NTFS)

it works on a 2.0 on both MY mac and on any PC, but not working on a 3.0 on my windows 7 64bit PC
