Autocad 2014 crashes/freezes in 3D while doing commands

Hello
This is my hardware specification:
Procesor: i5 2500
GPU: GTX 550TI
RAM: 8GB
Windows 7 64bit - clean installation + motherboard and GPU drivers

 

While I'm using each of commands (eg. Press/pull) in 3D view, AutoCad is freezing/crashing. While I'm pulling, there is no problem. It becomes a problem when I click again left mouse button - at best program is freezing and after 2 minutes is working (to the next function usage eg Press/pull) or it's crasing with Windows prompt - "End Now"/"Close Now"

While I'm projecting in 2D there is no problem.

System acceleration in Autocad is on (every option are switech to yes in system acceleration)

There is my project saved to:
[2014].

Why in that simple  5 minutes project there is a lot of troubles - my hardware is no so weak. Eariler I've got 2013 edition, and there was also the same problem (with student licence)
