i forgot to mention, a couple hour before i got BSOD when trying open some video file i create from Sony Vegas. it says atiamdgpu or something error. maybe this is related.
----------------------------------------
Sir, i think the 12.6 AMD Driver that i recently update is the problem. because when i clean uninstall it and using Win 7 built in driver the SVP can be opened. but after i reinstalled the driver, the problem before occur. 
i'll try revert back the Driver to 12.4  and see what hapen
-------------------------------------------
no luck. still getting the error. plus, i cannot open the Sony Vegas. so it seem the BSOD earlier responsible for this maybe. 
this is not hardware problem right?
