I built my system in January and had a flawless install of every software and
driver I have, my OS was XP PRO 64bit. My so-called upgrade copy of vista
finally showed up so I installed it. Unfortunately I had to start clean
because it was not an upgrade like the 32 bit was. I could not make any of
my software work except for office pro 2007. Go figure. I could not use any
of my Cad or sign design software. I got errors stating that I had a valid
image, but is for a machine other than the current machine. SO, fed up with
Vista I did another clean install back to XP PRO 64bit. Now I have the same
problems. My question is, Did Vista modify my BIOS, or did it leave
something on my hard disk. I figure a clean install should be just that. I
am no better now than when I had vista installed. I was wondering If others
had the same problem. If so what you did to correct it. Any help would be
greatly appreciated
