What I want to do is replace the current mb, socket 754. Via K8T800 chipset, with a different mb, socket 754, nvidia nforce3 250 chipset. I want to do this and preserve the existing XP install. In the past when I did such a swap I had to reinstall XP from scratch. I'm wondering if I can download the nvidia drivers, run the driver install program so XP has the drivers (even if they aren't active), then do the swap, and have XP discover the new chipset and install the new drivers. Anyone know if this will work, or will I just end up with an error msg or blue screen? Thanks.
