Hello,
i have just got a new asrock 960gm-gs3 fx mobo and amd sempron cpu i have put it together but when i start pc the heat sink fan spins but thats it no hard drives start and nothing on the monitor, what could it be?
I can't imagine that would be the problem. Do you have all your motherboard pins set correctly including 24-pin power, 8-pin voltage, and case headers?
