Unfortunately you can't mine anything with your GPU. Its a very old class GPU and no algos are designed for it.
The same goes for your CPU, your system is just too old.
What you have been doing is using the wallet's built in miner, which is usually a waste of time even with a decent
CPU. You can't mine that way with a GPU.
There are coins that can be mined primarilly with a CPU, it depends on the algo.
You can solo mine by setting up RPC in the wallet (research for instructions) using an external
CPU or GPU miner, provided you have a suitable CPU or GPU.
Solo mining generally requires a lot of mining power making it impractical for a single CPU or GPU.
Pool mining is more appropriate.
I'll leave recommendations for specific hardware to others, but that's what you need to start.
