I already have 4 GB ram but only 2.43 GB usable in my Windows 7 32-bit OS. If I install 2 GB more with 4 GB of old RAM, is it possible to do that to increase the usable RAM size?

A 32-bit operating system cannot address more than 4GB of memory. Putting additional memory into such a computer will be a waste. However, if you upgrade to a 64-bit operating system, additional memory will be found and used.

The link in David Postill's second comment above is quite useful.
