hp pavilion a230n memory question
Ok I'm a newb when it comes to computers but I got this computer from a friend who said it wasn't right he didn't want it anymore. Anyways I took it to best buy to see what was going on with it and the guy said that a memory stick was bad. It has (2) 256MB of DDR in it. My question is do I have to put 2 sticks in it or can I just get one bigger one to replace them? Also recommendations of memory to replace with. Thanks!
