I just bought a new computer which is: Intel DH67BL Core i5-2400 2x 2GB transcend RAM Inno3D GTS 250 Huntkey HK700-52PP 700 watts PSU I have attached everything but it still wont boot. When I press the power button, the fan will spin for a few seconds then it'll stop and computer will go off again. No BIOS. No POST mssg. I havent attached the chassis fan to the motherboard because the chassis fan connector is not compatible with the motherboard rear fan header. Will this board boot up even if i attached the chassis fan directly to the PSU? Or do I need to attached it directly to the motherboard's rear fan header?
