SolidWorks keeps crasing

When opening a part in SolidWorks or when making a part myself, SolidWorks keeps giving me an error message.
It states: "Wait while SolidWorks is running a command". When I wait, nothing happens, so I have to kill the program. This started happening a couple of weeks ago out of nowhere. I have tried reinstalling SW and even Windows. Nothing has helped. All other programs on my Laptop are running fine, even if the laptop is around 5 years old. 
It also happens that when SolidWorks is crashing, I get a blue screen. Here, a video_tdr error accrues. 
Reinstalling the graphics drivers has not helped. 
When running the SW diagnostics test, the results show my laptop is well able to run SW.
Thanks for your help
