render stuck

#1

hello
I have a rendering problem. from what I read I guess it’s a ram problem, but I wanted to ask if there’s a way around it. I have 8 gb ram on a inspiron 15 laptop.
even though rendering isn’t that slow, sometimes it gets stuck before it starts to render. with the message “Current Task: Rendering…”. it remains on this stage on specific configurations: when I use sss fast skin with Scatter indirect illumination on, higher diffuse bounces (10) and photometric light. also when I use sss fast skin with Scatter indirect illumination on, hair and fur and something like Daylight system.
can someone at least explain what is happening and if this problem would occur on a better computer?
thank you!

under Processing - Mapping I checked Skip Maps and Textures. it starts the render, but no textures.

object properties - mental ray - return black/ pass through gives similar results. I guess I was looking for something like that
