You need more memory from the sounds of things. The least you can do is increase the page file size.

This would be better being asked on the General Discussions forum next door.

I have 32 Gbytes of RAM and a page file size of 500 Gbytes. If this is not enough, it should say so on the store page, AND you didn't answer my question.

happens to me alot too, if you have mods maybe delete some. preferebly a bit older and not really useful stuff. if not, just start anew
