1)They stopped because 130538 was the number of the blocks in the blockchain when you posted! It downloaded all the blocks and well of course it stopped
You can check the number of the blocks here
Now for example there are 130550 blocks. And every about ten minutes a new one is discovered and will add to the blockchain
2)Well a quadcore will make like 10Mhash/s and the video cards just a bit more, nvidia isn't good for mining. An ATI 5830 can easily mine 300Mhash and a 6950 even 400 mhash or more
So i strongly suggest you to mine in a pool. with your hardware at current difficulties... use this calcualtor http://www.alloscomp.com/bitcoin/calculator.php
Put the mhash you are doing and press Calculate!
Oh i see you replied while i was typing.
The 9200 is useless, you need a card that support OpenCL to mine, so you need a 4000 or more recent (5000 or 6000) card. The 9200 you have simply can't mine.
