Should I Back-Up and Reinstall

[spazattack674]

I have had my MacBook for about 3 years now. As time has progressed, it has become slower. I have 2 GB of RAM, so it seems as though it should be faster. Would it make a difference if I were to back up all of my files and then reinstall OS X? And If I was do do that, would I just do an erase and install?

Thanks

Do not know about the last question but. Deleting old files and unnecessary programs will help, max out the Ram. Put your data on an external hard drive then re-install OSX maybe that will help.
