I Know iv posted something about my graphics before but now i wanna know is there a way to upgrade my graphics to use shaders now i really want shaders could any one help?

You might not be able to use shaders if:
- Your graphic card doesn't support Shaders 2.0 at least
- Your graphic card hasn't got the latest drivers.

Please tell us your Graphic Card's name (dxdiag).

You can only update your graphics card's software drivers (program), if your card isnt good enough then you will need to replace it with a better one (hardware - computer part).

So as fyerr said, all you can do is update your drivers, if your card is good enough then you'll be able to run shaders that way.
