No power: Most likely a simple answer to this one.

*Note: I’ve read the “Boot problems sticky and have gone through the list*

I have all the components now plugged in to my Gigabyte EX58-UD4P motherboard, and I’m finally attempting to start it. I have checked and double checked every wire…but still can’t seem to get the thing to fire.

Here’s the thing—on this motherboard, with the power chord plugged in and the psu switch in the “I” position, the “quick switches” (a power switch, reset switch, and clear CMOS switch) are blinking LED’s. So, it seems there’s power to the motherboard.

Also, each time these buttons blink, the fan twitches a little bit. But when I press the power button (I’ve tried the power switch led both ways) nothing happens.

Sorry if this is something simple, but its rather frustrating.
Thanks

    Does the power supply's fan always twitch (just a little) when its in the "I" position?
  3. No offense for this simple question...are the 24 pin and 8 pin power cables connected to the MB?
  4. Yes, they both are. I don't have any fan movement at all when I hit the power switch though. Which is interesting. Those are plugged in via the molex connectors from the PSU, not the mobo itself.

    Hmph.
  5. Starting to sound like a faulty PSU, which would be unusual because that's a quality brand. Do you have access to another PSU that you could try?
  6. I just did the paperclip test on the PSU and it passed fine.
    The front fan spun up nicely.

    So...now I'm again clueless haha.
  7. Got it to start!
    Didn't do anything different other than plugged things back in again haha.
    Idle temp is a little warmer than I'd wish it to be 42c...but I think that will drop once the artic 5 sets.
  8. Great. There was a simple solution. Congrats. 42 isn't bad for an i7 and you're right, it should drop once the thermal paste sets.
