I want to install Visual Studio 2015 on Windows 10. When the installation is complete, everything works perfect and good, BUT ...

...when I reboot my laptop (shutdown my laptop and then start it again) I get a Blue Screen Of Death that says "kmode exception not handled (cng.sys)".

Then it restarts and Windows starts successfully (but slowly)!
I check my MiniDump Error and it says a problem with "cng.sys" file!

I don't have any idea about what is going on, and I can't find an answer anywhere, so I'm asking it here: does anyone have any idea about what can I do?

I tried Microsoft Visual Studio 2015 Enterprise and Microsoft Visual Studio 2013 Enterprise, but I got errors on both versions! And for the record, I tried it on Windows 10 Enterprise and Windows 10 PRO

My laptop model is : Dell XPS L502x

Can anyone help me?

    An BSOD connected to cng.sys normally indicates a memory problem. You should run MemTest86 and verify your memory has no errors. – Ramhound Sep 16 '15 at 12:49
  • Be sure you run the DISM and SFC tools to repair any system integrity issues that you appear to have. – Ramhound Sep 16 '15 at 13:24

enter image description hereNot the cure, but a symptom treatment, disable fast startup. Go to Control Panel, Power Options, Choose what the power buttons do, Click Change settings that are currently unavailable and uncheck the Turn on fast startup option.

This prevents the bug in whatever driver is killing fast startup from triggering your CNG.SYS crash. Boots will be slower, but faster than the fast boot, crash, memory dump and slow boot that you're doing now.
