It could be a logic board issue, the RAM modules, or just the RAM modules not seated properly.
You can try reseating the memory.

It is not hard to reseat or replace the memory. You can find a video tutorials at ifixit.com.
If that does not work or if you are not comfortable open the Mac take it to an Apple Store for a free diagnosis and estimate of repairs.

If they say it is a memory issue you could take this opportunity to upgrade the RAM to 4 or 8 GB. 2 GB is small for running Mavericks and you would notice a significant speed boost if you upgrade to more memory.
OWC (macsales.com) and Crucial.com are good sources for buying the correct memory that is Mac supported and guaranteed for life.
