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.

Did you install the drivers for your APU (normal Catalyst drivers) ? – HackToHell Jan 14 '13 at 5:01
Yes I did. AMD Catalyst mobility drivers were used from AMD's site. – jtl999 Jan 14 '13 at 5:15
If it's a brand new machine I recommend you let Lenovo take a look at it and get it replaced if it's a hardware issue. – Karan Jan 14 '13 at 18:37
OK. Will think about it. – jtl999 Jan 14 '13 at 18:57

Got in for warranty service at a local shop. Turned out to be the HDD. Works great now.
