That's where I'm lacking. Not knowing what is embedded or installed in the mother board and what stuff comes from the original manufacturers disk. Finding the drivers like you mentioned is a good idea, but I don't know what drivers to look for. I suppose I could buy a newer motherboard.
I tried to locate the PC's original XP Pro CD from the guy that gave me the computer. It's from a business office. He had an XP Pro in the correct file, but it isn't the one that came with this computer. I borrowed it, thinking it was the right one, but when I put it in the confuzer, it said e CD was not compatible with this system.
