first and foremost... stop using windows xp.... now... if you insist upon continuing to use a 20 year old operating system that is no longer getting security updates from microsoft, as well as browser makers then you could perhaps try reinstalling XP. Now... on a side note, i will say that my kids computers are both core2duo's (E8400) and they are running windows 10 just fine. Both have GPU's though.. one a 640 GT and the other a 750ti
