Don’t know much about PC’s!!

Hey everybody, hoping someone on here is a pc expert and will be able to help me lol! So, I purchased this PC early last year, and I’d like to upgrade it, but I don’t know where to start!

It currently has an ASUS HB1M-PS-I motherboard with only two slots for RAM which is DDR3, I’d like to upgrade the motherboard, processor and graphics card but don’t know what to look for or what is compatible.

The CPU currently is an I5 but I’m not too sure which generation it is, and my graphics card is Nvidea GeForce RTX 3050.

I’d like to upgrade it to 32GB of RAM, to a newer or better processor (i was thinking of an I3 14th gen) but I don’t know if this would be compatible with the components in my PC? I’m not really clued up with this sort of stuff but I am more than willing to give it a shot! I’d also like to upgrade my graphics card to a 4050.

Please could anyone shine some light on my problems and help ? 😂

Thank you !
