i too faced the same problem...try following...

1) do factory reset (settings/privacy/factory reset)
if it doesnt works....
2) connect your phone to computer via usb cable..,but dont turn on mass storage....uninstall previously installed drivers, pc sync softwares on ur computer....and freshly download the usb drivers only from the lg official site.........

this is what i remember......just try...........
