I bought a new Thinkpad Edge E535. has 4GB of RAM and specs at the bottom of the post. It freezes randomly in Windows Explorer and sometimes it has problems shutting down. When I shut down the screen turns off when its about to turn off and the system stays on. Does not respond to anything except hard off via the power button. During these freezes Control Alt Delete does not work. I will add more RAM soon.
