I just bought a new laptop and opened it today right out of the box. Everything is working great except the usb ports. i have put in 3 different usb sticks. one 8gb size. one 16 gb size and one 4 gb size. one after another and my computer reads it for a second than disconnects and repeat. over and over angain. i cannot us a usb stick? there are 4, 3.0's on this laptop. it is windows 7 OS. its an i7-4700mq with 8gb ram and an nividia 765gtx graphics card. whats wrong with this computer? i have re-installed the drivers that came on cd's with the laptop, even thou everything else works and the computer booted up into windows out of the box, only asking me to set up a usear account for windows.
