it has hdd acoustic management
you'r drive got to support else it wont work
you can set min noise to max performance.
max performance makes more noise offcourse ;)
if you got raid0 you might try stripe size...
in case you still have problem
go to start -> run -> dxdiag go to display tab see if all is on
if not try to turn it on
else find driver cleaner google it
and clean drivers and reinstall
