The importance of upgrading laptop memory every now and then

I was scared as hell when my computer suddenly shut down and would not start. I brought it to my neighbor who knew how to fix these stuff and he told me the RAM memory could not handle everything I installed in the computer and it got busted in the end. He told me to upgrade my Apple memory to at least 2 GB as the current one was only 512 MB, a far cry from the minimum requirement of most programs installed in my laptop. He told me to go to www.memoryupgrade.pro, a laptop memory store and there look for an original apple memory so that I can have my computer up and running again. I did so and now I learned the importance of upgrading every now and then so as my computer will be able to handle more current programs and applications.
