I have been having this issue with multiple releases and multiple versions of the video card driver. I create a hole wizard hole, finish it and then click on the hole to edit it and my screen goes black, Solidworks locks up and slows to a crawl. I have addressed this with my VAR support and with the manufacturer of my system. I thought I had resolved the issue but after installing 2018 it came back exactly like it never went away. Any help on this would be appreciated. Productivity is suffering.
