Problems getting into mining

Alright guys, so before I started with mining with my desktop I mined with my laptop with an 3420 in it just to see how it works and to set it up for the first time with Slush's Pool . Started mining at about 20 Mhash. I get on my desktop download everything. Made a new worker, and I get nothing. |
I don't know what I am doing wrong.
I have done other pools too, I get the same thing.
Anyone have any solutions?
Thanks!

Picture of my workers:

Can someone please help me on this?

Just drop it. 350 Mhash/s (HD 7850) gives $10 per month(24/7) if electricity is free. Not even worth stressing the hardware. 

20 Mhash/s is like 60 cents per month.
