Black screen after installing cuda on Win 10 laptop with GTM 870

Hi there,

Apologies if this is an issue raised before, but I could not find my exact problem:

I have installed cuda 9.0.176 on my laptop with windows 10 (nvidia gtm 870), made sure that it did not install any graphics drivers (so just the cuda installation). However, after this my laptop screen is most of the time black (sometimes I do get an image on my laptop screen but then it will start flickering and go black again). An external display seems to work fine. I cannot open nvidia control panel either.

Anybody that knows what I can do to get my laptop screen to work again?

A lot of thanks in advance!
Vera
