As the title states, my MSI NF750 mobo only turns on if i unplug the 4 pin CPU power connector. It shut off on me the other day and now when i try to turn it back on the led's light up and fans spin for bout half a second then turns back off. At first i thought it was my psu cuz similar thing happened a while back and i just replaced the psu. But i took out the psu and put it in another system and it worked just fine. Then when i put it back in the F'd up system i forgot to plug in the 4 pin cpu connector and i pushed the power button and all the led's and fans started right up, but as soon as i try to power it on with the 4 pin cpu plugged in it wont start. Anybody have any ideas? Is my mobo shot? Or is it my cpu? and help greatly appreciated!! thanks!
