what OS are you using?
what I would try is a reinstall of the drivers.
go to programs and features in the control panel(W7)
double click the AMD catalyst install manager,do a CUSTOM(top one) uninstall of just the driver and CCC.
restart and then install the new drivers.Again CUSTOM and ONLY install the driver and CCC.
OH ya,and dont install the "gaming evolved/RAPTR" crap.
see if that helps at all.
