I just upgraded my mobo from a gigabyte M68M-s2p to a z87-d3hp, but if I turn AHCP on as the sata access method I get BSOD when booting to windows 7. I didn't re-install windows for the new mobo/cpu/ram, just used the same drive. It boots fine when I change to IDE... I had AHCI turned on with no problems on my previous mobo, so why wont it work with the new one? anybody have any suggestions?
