Rhino blackscreen

Hey guys,
I#m new to Rhino and finished my first project today. After closing it for lunch I wanted to change a few things afterwards and tried to open rhino again. All four viewing angles appeared black and as soon as I click anything it freezes and windows tells me that there#s a problem. I already deinstalled Rhino and installed it again but nothing I do seems to work.
Does anyone know what to do?
Thanks in advance!

Hi Finn -
Can you open Rhino without opening a specific file, that is, just start Rhino from the Windows Start menu?
If that works, please run the Rhino SystemInfo command and copy-paste the result here.
