Q: Ok I plan on getting a computer that has 3GB but could be upgraded to 4 GB, I was wondering how do you do that? Also, how do I check how much GB of ram I have on my computer?
A: If you right-click on My Computer and select Properties, it will show you your processor, speed, and RAM. To increase RAM, you either have to add memory in empty slots or replace existing memory with higher-density memory. You do have to make sure it is of compatible speed, though.
