I Am assembling my pc,with these parts which i have bought:
MSI GAMING 7 motherboard
Intel i7 4790
Seagate Barracuda 2tb
Corsair Vengeance 16gb(8gbx2)
Corsair cx750m psu.

When i fit the parts in my case,and tried to see if it starts up without having connected it to a display,I pressed the on button present on the board.It was glowing green.However,the processor and psu fans turn off after hardly spinning for a second.When i remove the ram and tr, the board sometimes switches on and sometimes not.Can someone help me?Ihave connected both power cables.
