Hi Yanni,
There is nothing wrong with the Quadro K2000 graphics card — it is the Nvidia graphics driver software that has the problem. So the simplest solution is to try newer and older Quadro K2000 graphics drivers to find one that works. As I mentioned before the Nvidia Quadro cards are a niche market and so my experience has been that the graphics drivers are less reliable than than the video game oriented Nvidia GeForce cards which have a huge market. There is no telling which specific graphics cards will be afflicted by graphics driver bugs. When getting a new card I would choose a widely used and current generation card that is within your budget. If you want to use stereoscopic shutter glasses that will limit the choice, probably requiring a niche card like the Quadro series. You can get some idea of the performance of various graphics cards on benchmark sites, for example
There are Chimera specific benchmarks here
There are entries for Quadro K2000 so people have found working graphics drivers — the table even says what driver they were using.
For a specific recommendation, if you want a current popular very high end card, an Nvidia Geforce GTX 1080 for about $600-$800. But there are many good less expensive options.

Hello Tom
You were right.
I removed the Quadro graphics card and installed a lower spec card (GT 710-1G RAM).
Then started Chimera and did the same movements. Chimera did not crash but the card was struggling to cope.
Rotating a structure with added maps was quite slow. After a while even the chimera menu became slow.
Could you please suggest to me a graphics card that chimera will be happy to "play" with?
Many thanks
