CPU no signs of power

I just changed out my mobo (Gigabyte GA-Z68X-UD3H-B3) because my computer no longer turned on. I bought a different power supply today to test if that was the problem but I am still not getting any power to the system. So new motherboard, different power source, no beeps, no lights. Suggestions?

  1. I suggest posting the rest of your specs, not much info here to go on.
  2. Go through this guide:

    Come back if this doesn't help you resolve the issues.

    Good luck!

    Went through the guide, still no power.
  4. So it was working at one point fine or never at all? Also, CM PSU's are not the greatest, switch that new one out if you can.
  5. Working fine then shutdown and would not load. When I had the original board in, it would turn on for a moment and 1 second later restart itself. No windows boot just constant restarting. Brought it to a tech guy at office store who ran test. Said PSU was fine, probably mobo. Ordered mobo but computer went completely dead before i installed it, no power. Installed new mobo. Still same issue.
  6. You made sure there is no damage to your CPU or the socket on your MOBO? Boot loops are usually CPU or RAM related from my experience, although the PSU could cause issues but if it has been tested I'd likely rule that out. Have to ask, you made sure your standoffs are correctly installed?
  7. I am replacing the old board with the same model. Would that make a difference?
