crashes are cause by a "memory leak", then you have software problems not hardware problems.The RAM, cannot cause a "memory leak"!
A memory leak problem is investigated in the Processes, Services, Programs, System Resources, and System Performance areas. Actually, your "programma (anti-crash), can cause itself a memory leak.
As for crashes in general, you start with a bare-bone system and gradually you add hardware components and software, ONE ITEM AT A TIME, until you find the item causing the crashes.
