When I reformatted and reinstalled all of Windows XP (last year or so), I feel I might have screwed up and somehow kept the other version on it. The reason I think this is because now, whenever I start up, it comes up with a black screen that asks which operating system I want to run. The options are 'Microsoft Windows XP Professional,' and "Microsoft Windows.'
Because of this, it's been running slower then normal.
Thanks a lot.
