I have a GB board (x58) and the Intel drivers "act" like they install (reboot and all) but, in reality, they didn't. Even when I ran it as an administrator. What I did was go to Device Manager and saw a good many yellow ! . So I did the following: 1. Opened Device Manager 2. Inserted MB disk 3. Highlighted a single yellow ! entity in the Device Manager screen. 4. Right clicked 5. Clicked "Update Driver Software" 6. Clicked "Browse My Computer" 7. Pointed it to the drive letter for the MB Disk and checked "include all sub-folders". Took a few minutes for the initial one...then went down the list of yellow ! one by one and now the device manager is free of problems.
