gateway ne56r49u low memory error

[tblu2326]

I have 354 GB free out of 488 GB, and for some ANNOYING reason, this error of low memory keeps popping up! I do have a sims 3 game (With 4 extra expansion packs) installed, but that still doesn't explain why I barely scratch my memory and yet I get a warning for low memory!

Low memory usually refers to RAM, not HDD space.
