Please check and post your system’s specs because:

  1. nVidia Quadro K620 is Maxwell and therefore unsupported beyond High Sierra (with which it requires the nVidia Web Driver).
  2. Intel HD500 graphics is a low-end mobile iGPU of low-end Apollo Lake SOC platforms and unsupported under macOS. It cannot be what’s fitted to a Skylake workstation such as the Precision Tower 3620. 'should be something more like Intel HD530 (i3/i5/i7 Skylake CPU) or HD P530 (Xeon E3-12xx v5 Skylake CPU).

 

Once you know what hardware you have, which is a pre-requisite, you may consult this thread:
