Replace Bad Core I3 Motherboard?

[jmarket]

Back story on problem: Bought new Windows XP Home Compaq Presario computer in 2003. That computer konked out Dec 2007. Took it to an independent computer shop where he built me a no-name computer and somehow re-activated my XP serial number on the one he built. I have no way of knowing what the serial number is, because the motherboard on the second computer gave out 2 days ago. The original Compaq was an IDE wit 32 bit. The second was was SATA and 64 bit. Over the years I now have 3 hard drives going on that, and a lot of good programs and files. One drive is the original XP with original registration from 2003, a second Linux Mint, and a third for storage.
What can I do about a motherboard? That one was a Core I3. Attached is a photo of it. Is is possible to maybe get an I5, and how do I reactivate my original XP numbers? Because I don’t know what they are, unless they’re on that hard drive. Thank you.
