MSI P67A-C43 fails to boot after attempted bios update

Hello TH,

I attempted to update my very old motherboard BIOS (P67A-C43) to the most recent bios provided by MSI. I downloaded and extracted the file to a USB, as the website requested. I left my computer temporarily while the BIOS update ran, and returned 5 minutes later to my computer boot looping. There are no beeps, and it simply enters start up and then resets, and repeats endlessly. I have attempted to enter BIOS (F11 while booting) and it shows me a screen listing all available devices (HDD, CD/DVD, UEFI...). I am able to hit enter on all devices and doing so simply causes the boot loop to continue. I inserted a Ubuntu Live CD into the CD/DVD drive which did nothing when selected or on boot.

Any help would be awesome, thank you so much for your time!

My cpu is a Sandy Bridge i5 2500k overclocked to 4.2GHz.

  1. Hi

    First step is to reset cmos to defaults to remove overclock (via jumper)
    Try startup again

    If that fails double check you have correct bios for motherboard
    Sometimes similar motherboard models have release 1, 2 or 3 with different bios requirements
    exact model should be on motherboard somewhere

    Does this board have a dual bios ? (probably not)

    Thanks Mike for the help. A few questions, how do I reset CMOS "via jumper"? Is that just removing the battery? And how can I flash back to a previous version of the BIOS?

    Also if anyone has any other suggestions, thank you ahead of time.

  3. Okay so I've reset CMOS and now when I attempt to boot with the USB inserted I am given the screen "Warning!!! BIOS ME update....file not found. Please add file to your USB."

    booting without USB still repeats same boot loop.

    Help is appreciated!
  4. Hey TH, still in need of assistance. How should I proceed?
