Radeon 6770M malfunction. DV7 CTO quad plz help!

I believe my graphic card is not functioning properly (radeon6770M). my notebook runs only on integrated Intel HD 3000 video card. Windows device manager register my graphic card but other applications dont(not even amd catalyst systray icon). when i disable intel HD card, radeon 677O wont start and windows device manager says that card reported problem(code43)  . i installed all latest bios/card drivers (sp53025,sp54024).laptop is brand new, the graphic card is not working from the very start. firstly, i thought that video cards are switching from power saving(intel hd) to performance (radeon 6770M) when needed, but when i ran benchmarks i had results only from integrated intel card. plz help
