Rhino 5.0 64-bit version freezes and does not work :(

I have bought Rhino V5.
I have a Lenovo laptop with Windows 10.
First everything worked fine. I want to work with the 64-bit version. And now all of a sudden it takes minutes to start up. The loading of the view ports are painfully slow. When it finally loads its not possible to work at all.
All commands lags for 20 seconds:(
How do i solve this??
Very thankful for any advice!

I got advice to update my graphic card driver. I did it and Rhino worked for a two days, then the problem was back:(


Could you have received a Win 10 automatic update since updating your video driver which set it back to an older one?
