VRay 6 and Enscape issues with RTX3070

I bought a Intel i7 with RTX3070 to work with Sketchup + Vray or Sketchup + Enscape. In both cases I’m having trouble. With VRay, if the quality is above medium, the computer suddenly crashes with the blue screen, with many different stop codes (Power state failure, Store Exception, Memory management, etc). In order to deliver my projects, I’m rendering the images in parts and it’s taking more than 3 hours to render each image.
With Enscape, Sketchup crashes with bug splat closing the file whenever I try to activate ray tracing.
Can anyone please help me solve my problem?

Regards,
