Computer won't boot. ASRock Z77 Extreme 4 Dr. Debug Error Codes 4F and 67

Hello,
a few days ago I reset my computer but when it tried to boot, all the fans came on for about 7 seconds then shut off. Every time I attempt to boot the same thing happens and I get the error codes 4F (DXE IPL is started) and 67 (CPU DXE Initialization) on my motherboard. All fans are currently spinning when I attempt to boot. I have been using the computer for over a year now with no issues.

Things I have tried that haven't worked:
Replacing the power supply.
Replacing the processor.
Replacing the Ram.
Clearing the CMOS

  1. Hi, Try clearing the CMOS and then starting with only CPU and CPU fan. See what code getting.
  2. Possible corrupted BIOS chip?
  3. 67 "could" be that your CPU fan is screwed on too tight:http://forums.tweaktown.com/asrock/50260-z77-extreme4-led-error-code-64-a.html
    Also could be making sure the RAM is seated Properly: http://www.overclockers.com/forums/showthread.php?t=705092
    Inspect the CPU/Socket to see if there are any bent pins: http://rog.asus.com/forum/archive/index.php/t-22755.html?s=55a1f5c1eecdb1a37d9e9000a25364fe
    And like the others said, could be corrupted BIOs chip, was there a power outtage/blackout recently? A powersurge could have damaged your computer.

    I tried that and got the error code 20 which doesn't have a correlating message in the instillation manual.

    Don't think it's that because I had thought maybe the entire motherboard needed to be replaced so I bought another one and the same thing is happening.

    Checked the CPU fan and tried different configurations, even tried replacing the CPU fan but that didn't work.

    Have checked and rechecked the RAM and it is seated correctly.

    I thought it could be the BIOS chip but that has been replaced because I bought a brand new motherboard and that didn't fix it.
  7. Additional Information:

    When I switch the power supply switch to on the computer immediately boots without me pressing the power button on the motherboard or my case. This led me to believe my motherboard was malfunctioning which is why I bought a new one. After installing the new motherboard I was sad to see the exact same thing keeps happening.

    I am all out of solutions.
  8. I FIGURED IT OUT!

    It was my stupid case. The power button was malfunctioning and I didn't have the sense to unplug it from my motherboard. Thanks for your answers.
