did the list of drivers help?
I can give you instructions to burn a Hiren's boot cd or flash drive, since the 7b stop code is a hardware error, and then you could hopefully boot into hiren's and see the xp install thru Hiren's desktop.
do you want this?
No chance of getting at any of that.does the office still have other pcs of the same type, or do they even have install discs, which they would have needed in the beginning.
