Yup it's a bit of things to read but you have to to understand how it work 

Because i'm partecipating in bitcoin for a while but never registered 

I suggest you to stick with the 5000 series, much better than the 4000. A 4870 for example make like 100mhash while a 5830 can go up to 300mhash and a 6950 up to 400

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.

About pool mining download guiminer http://forum.bitcoin.org/?topic=3878.0 and well register in a pool and use it to mine

Hi, i am requesting to be white listed cause i too mine at slush's pool and i need to communicate with him

I am not a noob, i won't make idiot posts about deflation and i won't try to reinvent the wheel by addressing non-existant problems with the blockchains and so on 

I know how bitcoin work, what mining is and how it work etc etc...
