I installed the Rhino 8 trial version on Windows 10 (Rhino 7 was working fine) but it keeps crashing once I try to open an existing file or draw a simple geometric shape like a circle.
I tried running Rhino on .net but the problem remains.
Hi David, Please open a new Rhino file and run the SystemInfo command and post the result. This is most likely due to your video card setup. Thanks
Thank you 
I just did, here the results:

Well, your integrated video card is way under spec for Rhino - even Rhino 7, surprised that it runs - and your video drivers are almost seven years out of date. You might try and update the drivers, but I still doubt it will run well if at all.
This may be helpful to update the Intel video driver: Updating Intel HD Driver
