2.) For some reason my Ethernet port doesn't work either. I don't know if this is because my internet provider (Comcast) won't accept two computers trying to use the same modem or what. I removed the Ethernet cable from my old computer and connected it to my new one and tried to use the installation disk that came from Comcast to setup my internet connection and it said that there was no device detected. I hooked it back up to my old computer and it works fine. I just have the modem that Comcast gives you for the self install.
The RAM isn't as big of a deal because Windows XP is only recognizing 3.25GB of the 4GB that is installed anyway so it won't recognize anymore anyway, I don't think anyway.
The Ethernet thing is a little more of a problem. I kind of need the internet lol.
