I'm not a technician but from what I hear this be a lot of things. You might want to try installing all the newest graphics (ATI\Nvidia), processor and mainboard drivers and the newest version of DirectX. Since you have a laptop it will be much easier to track all of them. If else fails there is not much you can do because the company that created PANZERS went bankrupt and the producer CDV doesn't officially support the game anymore. The only other site that could help you is kanelx.de.
