Windows 10 using all my ram

[xCaleb]

I've been having some trouble with fallout 4 recently, it will play nicely for about 5 minutes and use about 2 gb of ram, and then my system will start using a lot of ram and fallout 4 will slowly lose all its ram.  After a while my system is using up most of the ram and fallout 4 only has a gigabyte of ram to use.  This causes it to be laggy and unplayable.  I don't know why my system is using up all my memory every time I play but it is causing the game not to work, I have 8 gbs of ram that should be enough.  Why is this happening and how do I stop it?

Check task manager when you're in game and see what is actually using up the most memory.

I have, the process using all the memory is just called "System".

Have you ran any anti-virus and anti-malware scans lately? That is definitely not normal.
