Games : How can I connect my PS3 controller? [Resetting, and changing battery doesn't work.]

I had this ps3 controller for a year. Now it won't connect. I plugged in the cable and pushed the PS3 main menu button but unable to connect the ps3. Tried with all the other cables too. I also tried reset button but still no connection to ps3. Then i thought it was a battery that need to be replaced so I replaced it. The result is the same. I dont know what the hell is going with my ps3?

*Also I changed the usb slot to see the result. So far there is none.
