Unreal 5.3 Preview 1, Monitors goes into power saving mode

Hi, I am using Unreal 5.3 Preview 1, I have created a very simple scene around a car, but when i am rendering in path tracer, the moment i hit render i can see the screen and than it goes black. if i try continously it crashes on pathtracer viewport also.i have no idea why this is happening.
The things i have tried. changed the nvidia drivers, trying it on a fresh windows build, my bios is also updated, tried some old drivers of nvidia also. removed some rams to check but its still happening. any ideas you guys could suggest what i am missing.
My Build is Dual Xeon and Nvidia 3090
