Unreal Engine been behaving extreemely unstable when doing tasks

After changing to a new PC build recently, with an AMD cpu instead of Intel, but same 1060GTX gpu, I’ve been experiencing a lot of instability when working with Unreal. The engine sometimes just crashes on randomly mildly demanding task, such as switching to landscape tool for the first time, loading sublevels, finishing compiling shaders, enabling wireframe, etc. It’s not always that crashes occur, only sometimes, leading me to think there’s some instability with graphic drivers or the like, but I have the latest version.

Anyone has any idea what could be causing this?

Here’s the crashlog:

Fatal error: [File:D:\Build++UE4\Sync\Engine\Source\Runtime\RenderCore\Private\RenderingThread.cpp] [Line: 826]

Rendering thread exception:

Fatal error: [File:D:\Build++UE4\Sync\Engine\Source\Runtime\Windows\D3D11RHI\Private\D3D11Util.cpp] [Line: 251]

I’ve had a lot of issues recently as well, where simple things like editing transformation in a widget causes the engine to die.
