Hi, I am pretty much a computer dummy, so here is a question this dummy hopes will come across well enough that someone may be able to answer it. I have an eMachines desktop computer built in 2005 with 512mb ram. A friend upgraded the memory in his 2008 eMachines desktop, and has two sticks of 512mb ram that he will sell to me. Will my friend's ram from his 2008 eMachines fit and work in my 2005 eMachines? Thanks for any help!
