Another OS paged pool memory question

Is there any way to fix this or/and increase the paged pool memory size? Mine is currently 384MB and for some fucking reason I can’t play any more of my maps, I can play flatgrass and thats it. Someone, PLEASE help me?

Note: This used to never happen until I started playing again.

I have the same problem.
