You can't just do that unless the underlying hardware of your computer is 64 bit. The 64 bit version of Windows XP released on April 25, 2005 will not run on a 32 bit computer.
If your computer is 64 bit then you can move to 64 bit XP but you would need to purchase this from somewhere. I am not sure but I do not think Microsoft supports or sells this any more.
If you are having problems, may I suggest you try installing Linux instead (for free in either 32 or 64 bit versions) it will work much faster then Windows. See related link below.
