Hello,
this morining when i've tried to switch the power on, the motherboard start for one second with fan....the stop and restart....and it's in this loop.
I've tried to put only less memory...change video card....nothing to do, it continue to make this loop.

What's wrong? do you think has failed the motherboard? the psu is a corsair cx750m.

i do not understand...until last night everything was ok...this morining let's start badly...what do you think about it?

as suggested in other formu, i following this procedure...

The clear CMOS jumper and reset factory defaults are not always effective in solving BIOS value corruption and so the only other recourse is to remove the CMOS battery. Many people are aware of this method but fairly often it is not done correctly and hence does not resolve the issue. Below I will outline a foolproof method to achieve a full CMOS clear.

1. Disconnect the system's power from the wall
2. Press and hold the power button for 10 seconds to be sure residual power is discharged
3. Place the "Clear CMOS" jumper in the clear position
4. Remove the CMOS battery
5. Leave the system in this state for 4 hours. 10 minutes is enough in most cases but if that yields no result then to be absolutely certain CMOS is clear I recommend 4 hours.
6. Place the "Clear CMOS" jumper back in its original position
7. Replace the CMOS battery
8. Power on the system

This method should effectively rule out BIOS value corruption as a culprit during troubleshooting.

BIOS value corruption = corrupted settings in the BIOS
BIOS corruption = Corrupt BIOS/UEFI firmware due to a bad flash
