Error:Out of Video Memory Trying to Allocate a Rendering Source

I am fairly new to the engine. I just started it up and made my project. After that I clicked on my project only to have an Error screen pop up saying “Error:Out of video memory, trying to allocate a rendering source” I tried doing the first 2 options it recommends me doing. The only option I have left to do is to is to change my video card to its maximum storage. I am not good with computers and don’t know lot about them. And I share a computer and only have this one so if anything happens to this one than we won’t have computer anymore. So I don’t want to do a sketchy download.

what video card do you have? Check UE4’s Hardware Requirements:
