Unreal Engine keeps crashing

My Unreal Engine was working perfectly but today it keeps randomly crashing. It happens even when I start a new project and after reinstalling the latest Unreal Engine version. It crashes whatever im doing but usually after opening the level blueprints.

I have attached the Crash log.

Any help would be appreciated. Thanks

[2018.06.14-15.54.42:665][415]LogD3D11RHI: Error: Result failed
at D:\Build++UE4+Release-4.19+Compile\Sync\Engine\Source\Runtime\Windows\D3D11RHI\Private\D3D11Query.cpp:140

The driver is crashing, not to mention UE4 tries to use intel GPU which not goes very well with it. look on rest of the log:

[2018.06.14-15.52.28:318][  0]LogD3D11RHI:     Adapter Name: NVIDIA GeForce GTX 970M
[2018.06.14-15.52.28:318][  0]LogD3D11RHI:   Driver Version: Unknown (internal:Unknown, unified:Unknown)
[2018.06.14-15.52.28:318][  0]LogD3D11RHI:      Driver Date: Unknown

When UE4 tries to use NVidia GPU it has problem to get information about driver, so best course of action is to try install latest driver from NVIDIA site (not from Laptop manufacture)
