[Crash] Building on First Person Sample

Hi

I’am using the latest version of the Unreal Engine (4.9) and I can’t build the light on level (by instance when I’am delete a static mesh, it’s shadow is still present in the scene)

When I build the light I got the message from windows which said “unreal engine is not working”, Here is my configuration

Intel(R) Core™ i7-4700HQ CPU@ 2.40Ghz , 8 go RAM and NVIDIA GeForce GT 750M

and the log

Is my computer performance is to low to work on Unreal Engine, do I need to buy a new computer ? Because I can’t work if the quality of the game is to low.

Or may be I can’t build light with lower performance ?

Thanks all

Edit : I event got this crash on Tappy Chicken sample

According to the spec recommended by the official site my processor seems to low, at least 2.5 ghz is required. But mine is 2.4…

Can someone confirm what is the good configuration to work correclty with Unreal Engine 4 and not buy a new expensive pc each year :S

thanks !
