Hey guys, person just brought this laptop to me running win7, claiming his wife says it freezes when online and a popup appears, I am waiting for his wife to call me to explain further as I am not seeing any of those issues, the net is working fine and no popup appears anytime, I can navigate around his system fine, laptop works fast and normal. What I am noticing is that it will not shut down using the start tab, also won't restart, it will only hibernate so only a hard shutdown is working. Also pressing ctrl+alt+delete is not bringing up the task manager, any ideas please?
