is it a dual head? as in dual monitor capable (doesn't matter if using 2 or not)... if so, go into its properties and make SURE that the 2nd monitor/head is disabled and apply it. check dxdiag make sure everything is enabled, also goto display properties (advanced properties) and make sure hardware acceleration is at full).
