Can I add more RAM to a Lenevo-C200 computer and make it stop freezing up?

This computer is 4 years old. It freezes up often. I have gadget app guages that shows CPU usage that stays on the low side but the RAM guage shows often 95% usage. When I look at the properties for the RAM it says 1 Gig. These are the othe specs it has...
Windows 7 Home
Intel (R) Atom(TM) CPUD525 @180GHZ 1.79GHZ
1 GIG Ram
160 Gig HD
32 bit operating system.
Sorry, I just like how the computer is set up in the monitor and would like to make it better if possible. It was free so, well, you know.

Staples offers free tune ups, they will also check if that might be an issue and can get matching ram..
If you have microcenter within range, go there..
