I guess your card (GT250) is too old to mine XMR. I think you bought a second hand computer because that card is like really old (2009).
The only way to learn and understand mining with this setup may be to read this book : Mastering Bitcoin by Andreas M. Antonopoulos
Chapter 8: Mining and consensus, there is a very simplified Proof-of-Work algorithm implementation in Python.
Note that XMR and BTC uses different algorithm (Cryptonight and SHA-256, respectively). But you ll still get the hang of it from this book, I guess its a good start.
Good luck!
