How full is your hard drive? There are 2 things I can think of off the top of my head. 1) Your hard drive is close to full so swap (or the windows equivalent thereof) can't expand when it needs to and gives that error. 2) You're using an older save file. The save files apparently can balloon in side depending on a lot of things. One of which is how often you rollback.
Like, my laptop here is over 5 years old and it's handling it fine so that leads me to think there's something going on with your game and/or system.
