Ok lil background info:
Its a Gateway 700S (1.8ghz Pentium 4, 256mb Ram) running XP home, with no problem. Decided to upgrade it to XP Pro SP2 for IIS, and some other features. (The system meets or exceeds all the Requirements for XP Pro).
Anyways, I formatted the drive and started the install of XP Pro SP 2. During the "Installing Devices" part of the install it gives me the blue screen of death and points to nv4_mini.sys as the problem, which is a "NVIDIA Miniport Driver." My PC is running the 64MB NVIDIA Geforce2 MX400 AGP graphics card. I tried restarting the install, and it failed at that point again.
I then formatted the drive again and installed XP Home (Using the Disk that came with the computer) again, XP Home installed with no problem. I then tried doing an UPGRADE to XP Pro instead of a Fresh install. It again died at the "Installing Devices" section of the install, but instead of a blue screen of death it restarts my computer. I tried to resume the setup but it again failed and restarted.
I then tried installing a different copy of XP Pro that I used on my other computer (Just in case the CD had some bad sectors or something). It again died at the same area.
So for the moment I have reinstalled XP Home, until I can figure out whats wrong.
So please if anyone can help it would be greatly appreciated.
