I might be able to help if I had a little more info. I need to know what hardware it's got (proc type, number of ram slots and type, number of pci/isa/agp slots) and/or the bois id string and the bios type. It is probably AMI or Award bios. The string will appear at the bottom of the first boot screen when you boot up the computer. It will be a real long string of numbers and letters. If it goes to fast to get it all just push the pause button on your keyboard to halt the boot process right there.
