is there a program I can download that will identify the motherboard in my computer ? I dont want to open up the puter unless it is necessary . ( too much junk to unhook ) . puter is a Sony RX540 with a 1.2 celeron processor and I`m wanting to upgrade it if possible .. also , thinking about adding an AGP card , current video is 11 meg shared , onboard , is it worth it ??? thanks for any help , Bob
