Hi,
In a first time, i'm french user and i apologise for my english.
With my motherboard DZ77BH-55K, sometimes, but not always, the boot fail and i have the message : "BIOS has detected unsuccessful POST attempt(s)... Press "Y" to enter Setup or "N" to cancel and attempt to boot with previous settings." And if i press "N", after on OS (seven SP1), the system works fine, no problem. I attached my technical configuration with the Intel utilities.
All of my stuff works fine with another motherboard, it's the same materiel what i plugged on this intel motherboard.
So this message in the BIOS is useless, because my setting in the bios works with no issues, but it's a little bit boring... i don't want start my PC with my fingers crossed for a boot with no issues. I tried lot of setting, turn off some plug and play abilities, manual setting for video card, the last setting what i did is disable "general optimisation" in boot option. I don't know if that works for the moment, i don't shut down my system again.
And another detail, this problem happen only after a night when i shut down my system. My power supply is plug and ready to go.
If i try simple reboot, no problem, and totally shut down then reboot after a short time, no problem.
Thanks for help.
