I just did a clean install of XP on my new Dell D630 notebook and have a problem. I've done plenty of clean installs before and never run into these problems.
I checked the Device Manager after installing my drivers/windows updates. For some reason, I'm showing 2 ACPI Batteries, 2 965 Chipsets, 3 plug and play monitors, 2 Core Duo processors, and several system boards... all I can think of is that there may be newer drivers I need to download (I used the drivers/utilities disk). I actually had 2 copies of Windows XP showing up when I booted, but one was not actually present, so I deleted it from the boot.ini file, which did nothing.
I thought that this might just be a feature of intel chipsets and did a little research. I found this: http://www.intel.com/support/graphics/intel945gm/sb/CS-..., which explains the monitor situation. It also occurred to me that I've never had a dual core processor, so maybe having 2 show up is normal... but 2 batteries? 2 Chipsets? Multiple system boards (I assume I'm asking a newbie question here, sorry )?
