Have you considered to use Linux? PoE runs under Linux. I am doing tha and it works perfectly. Generally Linux's system requirements are a bit lower than Window's. So on your aged computer it might be a good choice. And it would cost you nothing. But it depends. Are you running any software that desperately requires Windows? Any hardware that does not work with Linux? If not I would recommend switching to Linux. I am using it for over 10 Years now and am barely missing anything (just a few games...). You could also run a dual-boot system if you have enough space on your harddisk. So you would only boot Linux to play PoE and use Windows for everything else. Although I would recommend to do everything internet-related on Linux as well as this would not expose your WinXP computer to risks any more. GoG writes PoE it runs under Ubuntu 14.04 and Mint 17 so you could use anyone of these. I recommend Mint 17. I am even running PoE under Arch Linux without any problems.
