BSOD thanks to win32k.sys - Any ideas?

Hi guys,

i am getting now the 10th BSOD after using my notebook for standard for writing emails (outlook 2013, reading PDFs with Adobe and writing messages with lync 2013.
I haven't installed any new software and i haven't change the hardware.
I already have run the Windows memory Diagnose Tool without finding any errors.

Could you help me with finding the reason for these annoying interruptions?

Thanks a lot
