ASRock Z77 Extreme4 won't post, no lights

Hey I just picked up a Z77 and i5 3570k at microcenter for damn cheap. I'm replacing my old i5 and P55 board that burned out over the summer. I got it all hooked up and it won't post. The fans spin and the HDs turn on but the power button on the board won't turn on and I don't get the diagnostic code thing either. Even with nothing but the board and power supply I should at least get lights and an error beep.

I checked the board posts and made sure they're only on the rimmed screw holes to see if there was a short. I pulled the board out and ran it on a box and that didn't work. Clearing CMOS didn't affect anything either. I'm beginning to suspect my power supply, though it turns on fine and everything else seems to turn on fine as well. When my old computer went out this summer, it was exhibiting the same symptoms of turning on but no board lights, post. I even bought one of those post code testers and got nothing. When I plug the tester into the z77 it turns on but doesn't tell me anything.

I really hope I don't have to RMA the board because the closest microcenter is like an hour by train.

Any ideas?

  1. bump
  2. Could be the ram sticks, your ram is @ 1.65v the ivy bridge is 1.5v recommended, check also the qualified vendors list.
    Check with other ram if it the problem still persists.
  3. I hadn't checked that. Didn't know there was an approved list.

    Even without the ram in the board should beep or something though.
  4. had the same problem mine seemed to be the psu once replaced it worked fine.
  5. First, bumping is against the forum rules.

    Go through this, just to make sure you haven't overlooked something - It happens to all of us, and this will help make sure everything is right.
