The message that you see, do you see that before Windows boots? (Do you use Windows? You did not include that in your specs. What version if you do?)

The message you get, "The system failure to boot several times ago... ", seems to be the message from the Boot Failure Guard feature. The words are not all correct, I imagine you are remembering them, and they are not in your language. I am not aware of another message like that, so unless you see it when Windows is booting, it must be from the Boot Failure Guard feature.

This feature (this option in the UEFI/BIOS, is in the Boot screen, and it uses the Boot Failure Guard Count option) can tell when the board cannot POST, usually because of an over clock that does not work. It then starts POST over again, and tries the number of times (1, 2, or 3) the Boot Failure Guard Count option is set to.

After that many attempts to POST still fails, the message you said you see is displayed, and the default settings of the options that were changed for the over clock are used, so the PC can POST and boot normally.

That is how this option normally works. It might be possible the new BIOS version has a problem and is causing this message to be displayed by mistake. Some questions for you:

Is your 4.3GHz OC working when the PC boots?

When you start the PC after being shut down for a long time, does it take a long time to start? Does it seem like the PC is trying to start, and then starts over again two or three times?

Normally when you see that message, you also have the chance to go into the BIOS and change or fix the OC settings. Do you have that option when you see this message?

If you restart the PC after it boots fine, you do NOT see this message at all, is that right?

You are now using the Broadwell-E compatible BIOS version (did you update to 3.30 first, or did you just use 3.40?) with your Haswell-E processor. You can do that, but did you update to the new Intel Management Engine driver ver:11.0.4.1186 software?

You must do that, or your over clock will not work. I wonder if you really have your 4.3GHz OC when Windows (?) boots now. I think that you don't have you 4.3GHz OC working because of the new 3.40 BIOS version, and the Boot Failure Guard feature is telling you that it is not working.

can nobody help?
