CRU crashes my PC when i install a newer NVIDIA driver.

I've been using CRU for some time now, and it worked fine. But when i try to install any other NVIDIA driver (other than the one i was using), my pc crashes, and after rebooting i see that the gpu device is disabled. Now the only way i can use the CRU is by reinstalling my old driver, but then i won't be able to use some features of the newer one... Does someone knows what's causing this, and how to fix it?

GPU: GTX 970
DRIVER VERSION: 456.71
