Newly built computer doesnt work again

[bozosayshi]

When I plugged in my DVI monitor into the computer, it just says no signal. The motherboard isn't making any kind of beeping noise, but IDK if its supposed to do that right now or later. Could it be the GPU not giving a signal to the monitor, or the mobo being faulty hence not beeping (but the LED's and everything is on, and everything else seems to have power)

Thanks..

Was the computer working and now it's not? Did you plug in the 4/8-pin CPU power connector on the motherboard? What are your system specs? Sorry for all the questions, but you'll have to provide a little more info if you expect anyone to be able to help you. There are a lot of reasons your monitor might not be getting a signal.

No the monitor has never turned on nor has the mobo ever beeped. Everything is plugged in. Specs:

The 8-pin CPU power connector is pretty easy to miss on that motherboard. It's located under the cooler that says EVGA on it near the CPU socket.

That's the most common reason for no monitor input. You could also try booting with just one stick of RAM installed if you're absolutely sure the 8-pin CPU power connector is plugged in.

www.moddersmart.com has the Noctua NH-U12P SE1366 cooler in stock. It's a great cooler and I've seen i7 920's do 4.2GHz using it.
