These appear to use the same motherboard chipset so head to Crucial.com and get the W3506 memory sticks.
"Would I need to buy a new modem?"
Odd question. Why would you need a new modem?
I have an eMachine with 512MB of RAM which is now at 448MB. I need to upgrade to 1GB but I can't find a store that carries this model. The model is a eMachine W3507 and runs Windows XP home edition. Would I need to buy a new modem? I can't download because it tells me my memory is too low. Can anyone help me with this?
maybe your confusing "memory" with storage. hard drive space?

Help, my PC with Windows 10 won't shut down properly
Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
