Hello everyone,

Following a mishap (BIOS update via an MSI update), my PC only turns on and off without booting anything.
Do you have a solution to flash the BIOS again? I've already tried clearing the CMOS but it didn't work. I've tried techniques found online but nothing seems to work...

My motherboard: MSI Z77A G45

Thanks in advance ;)

    Somebody help me? I think I'm going to return the card with the warranty. After all, the update was done after a MSI software on an MSI card and I followed all the instructions.
    hoping they will repair or exchange it for me... :S

    Hello

    Why did you flash the BIOS?

    Do you no longer have the option to enter the BIOS?

      Hey,

      I had a little memory management problem, so I wanted to flash to see if it would solve the issue. I messed up by using MSI's live update 5 under Windows. I should have flashed directly via the BIOS.

      And no, I can no longer access the BIOS. My PC turns on for 5 seconds, seems to try booting from the SSD or the Blu-ray drive, then shuts down... and restarts, shuts down, and so on.

      Try after unplugging everything that isn't necessary.
      The goal is to enter the BIOS only, so keep only the graphics card and one stick of RAM.
      If that works, reflash the BIOS (with a previous version)
      If that doesn't work, return it for repair, but without specifying that you failed a flash.

      I did it too, I left a RAM stick and even unplugged my graphics card (the one from my processor being sufficient).
      I just tried an MSI procedure but there's nothing to be done, it doesn't seem to care at all.

      I agree with you about the customer service, do you think it could work if I act dumb saying "uhh I don't understand, one morning I turned it on and poof, nothing!"? :)
      I don’t know if they have a way of knowing it’s because of a flashing...
      At the same time, I did it through one of their programs, so I have something to complain about! ^^

      The card is to be sent to the merchant who sold it to you, who will forward it to the customer service or refund you, depending on the warranty agreements they have with the wholesaler.
      It is a relatively recent model, so it should not pose a problem.
      If it goes to customer service, it will take a few weeks (there is a MSI customer service center in France, which is fortunate).
      They can indeed detect that it is due to a failed flash that the card no longer boots, but I doubt they will take the time to diagnose it, and since there is still a bit of life left as it starts up, they will repair it (probably by changing the BIOS chip) without looking any further.

      Okay well I'll go for the blonde anyway. Anyway, whether it's repaired or new it doesn't matter as long as it works...
      hoping it doesn't take too long either :s

      In any case, thanks for the info ;)

    This card has an M-Flash function that allows you to restore the BIOS from a USB key, no need to send it to customer service, everything should be in the manual if I understood correctly.

      Yes, indeed this function is super useful except that... It's done through the BIOS and I haven't created this USB key (of course, otherwise it's not funny!).
      I set up my configuration three days ago and I unfortunately didn't take the time to do it.

      I thought we could place the unzipped BIOS on a USB stick and during boot we could launch the update using the delete key (on my Asus it seems that's the case but I haven't tested it)
      for my next purchase, I will therefore choose a dual boot card.

      I admit I haven't had the time to test it. What I understood (but I could be wrong) is that with the key, the PC boots directly from your key and launches the BIOS from your key without going through the EEPROM BIOS...
      I will test it when my board returns from service.

      I have a Z77A-G43 and this function is also present, but it must be used before a crash...
      It looks like the EZ-flash function from Asus, but not as good.
      Moreover, this kind of "gadget" should be avoided (except at Asus where it's mastered), it doesn't always work and doesn't really help when the BIOS is corrupted.
      With MSI, every time I've flashed, I've used the Live update function but it has always worked for me.

      Ha ok, so I really wasn't lucky lol.
      And you say that in case of a crash, the key is useless?
