Are you overclocking? Look over the card's cooling.

open directx in the command line and see if you see any errors.

start,run, dxdiag. What version of direct x are you running? Have you updated your drivers lately?

 

[KiteOrca]

there is no errors,my direct x version is 9.0c.
Looks like my card is already broken,i bring my card a to a comp store near my house,they said my card is broken,and i think maybe it's time to go to pcie...
