I'm surprised you didn't have it completely wiped, as that's normal procedure for computer transfer...
But anyhow, I'd get the latest drivers for everything (if you haven't already.) Create a restore point in System Restore, and then try deleting those two references. Then, if all goes well, install an newer version of the graphics AND chipset drivers.
Normally that is what I would do. She has the recovery disk and the reinstall for XP Home. I am really intrigued by that machine! She did nothing but pay bills on it and file her taxes. Otherwise, it was pretty useless to her. There is a 'story' involved here: she bought it from Wal-Mart in 2008, took it home and when she turned it on, there was already a 'user' on it, with thousands of files, some dating back to 2003 (including the overclocking). She says she took it back and they said something like: too bad, how sad. As ignorant as she is, IMHO, I think she was trying to pull a fast one on WM. At least that is the mind-set.
So I will get the system restore disk and any other disk she has and go from there. Thanks for this answer. Will be getting on that in a bit.
