upgrading an XP 2003 HP
Can I upgrade my HP 2003 XP Desktop computer? If so would it be cheaper to do that or cheaper to buy a new one?
Probably cheaper and easier to just buy a new one. A computer that old would need a serious overhaul to be up to today's standards. You could buy a windows 10 pc for as cheap as 200-300$. I would just upgrade to a new PC.
