scrolling not smooth

I have re-formatted my PC this morning and installed all the drivers (via device manager)plus MS updates and everything is fine except the page scrolling,it is jerky instead of smooth how it was before.
I have tried various setting for the mouse (1 to 6 lines) but nothing seems to get it smooth.
Any suggestions please?

 

You may want to check your video drivers, I get that with generic drivers.

 

Hi Algis
I have loaded the driver from the disk that came with the card it's 185.02. i am hoping to get the folding right on this PC then set to work on the other one.
