gtx 750 ti error

[petridian]

today while i was playing i noticed an unusual change in my fps just to be sure i opened furmark(gpu stecher) to test my card anf guess what from its base clock 1202 mhz it used for some reason only 405mhz i tried to overclock it via thundermaster but the speed stayed at 405 mhz!! my gpu is gtx 750 ti storm z dual 1202 mhz 2gb
