is there a minor coin that I could mine with a simple Win7 PC?

[PurpleDog]

Hi everyone.

Is there any minor coin that I could mine with a simple PC and Windows 7 64bit? (cpu: Intel Pentium G3260 3.30GHz and 4 GB DDR3 SDRAM) ? and very low electricity costs.
If yes, could you direct me?

I'm not looking for great gains, of course. More for the experience and making a small stash of anything.

thanks
