graphics card

Hello,

I am using the graphics card P520 quadro from Nvidia for creo 9.0.

This week suddenly an error message appeared (see attachment ...547_n.png below) during me drawing some stuff. Then when I tried rendering, the rendering screen went all black. 

Rendering since goes very slow and the message keeps appearing. 

I updated the NVIDIA drivers, checked the OpenGL version - it is 4.6 - and wanted to check the hardware, but the latest checker software - that I could find - for this is one designed for creo 8.0.

I just noticed that the program does not use the quadro graphics card, but instead the intel cpu (see troubleshoot Word file). How can I solve this issue?

Thanks!
