How Do I Start? [BTC]

From memory CPU mining is really slow, you want to use the processing power from your graphis card (could be wrong) Maybe upgrade your dvd player . Your specs probably aren't good enough to mine effectively but if you can spare the cash then build/buy a dedicated bitcoin mining machine or rent some cloud based services which would be much better for your situation. Although depends on your interest, if you want to use bitcoins just to do shady transactions then once you are considered "trusted" you'll be able to participate in currency exchanges eg. PayPal for BTC. If you are doing this to make money then I suggest you go with what I have mentioned previously.

Also you need more than a wallet to mine lol, check out popular mining pools. If you need help getting started just flick me a pm I can explain this more in detail.
