Immediate startup after shutdown

[Anathos]

Hi guys, everything seems to go well, but after I shut down my hackintosh, the machine starts up back again. Did anyone experience this as well? First impression would be that it could be some hardware issue (cable etc.) but when I had windows 8 installed, it never happened.

my HW:
GA Q77M D2H
i5 3570k
16 GB Corsair DDR3
1TB Seagate
EVGA Nvidia 640 GT
DELL 875w PSU 80+ (j556T for alienware pc)

check your settings on the bios,make sure your start up disk is the hd you have your os x,that did it for me.
