Just wondering if anyone else has this problem and if so, have you managed to fix it? It seems after I plug the adapter in for a certain amount of time, the PC completely freezes and all I can do is press the restart button or, turn off the PC and then back on again. I'd say it freezes after about an hour or so of use. Unplugging it before the hour is up and then plugging it back in later still causes it to freeze = /
