Help for Sandy Bridge Desktop OpenCore!

Hi i have tried OpenCore with my Desktop PC for about. a month now but i'm unsuccessful. I have followed the OpenCore guide and things but every time i try to boot its black screen not OpenCore menu. I have followed the Ivy Bridge guide sense theres no Sandy Bridge guide, The other thing I'm stuck on is I'm not to sure how to get these files! SSDT-PM SSDT-EC SSDT-IMEI
