My PC keeps freezing

So, let me be fast, I have used unreal engine for about a month and when I open either a big scene, or export something, all of my PC keeps freezing. I have an NVIDIA 1060 so I do not understand what is the issue. I always have to restart it and it takes so much time of building.

P.S, please answer as fast as possible for me to finish Spring Jam 2020.

Thank you.

It may be freezing because of following reasons, Engine is Compiling Shaders ,building lighting. If you are opening a scene for the first time engine will compile shaders and generate derived data cache so that when you open it for that next time it wont have recompile shaders. And also building lighting may also cause your system to freeze as it uses most of your cpu and also Disk to read and write data. Its not issue with your graphics card and its a common thing I guess (it happened to me many times) .Mainly its because of Processor and Disk.

Cheers!
