[yafatana]

as I said sometimes when I restart my computer
it shut down completely for a sec and then it start again normaly to desktop

it.s a new build
no error codes on the led panel of my motherboard

i76700k
z170x gaming 5
ram gskill 16 GB F4-3000C15D-16GVR
VIDEO CARD sapphire r9 390 trix 8 GB
psy seasonic g650 650 watt

maybe because im using master slave outlet like that one ????

My old motherboard did that too, and I could never figure out why. It was reminiscent of a failed overclock, but bios settings were intact after the "shutdown and restart". It wasn't a problem though, so I just lived with it.

but that.s a new motherboard
and also the motherboard does not report any proplem code on the led panel .

I think i've had this problem before cause of a low/dead cmos battery
Does your date/time get all messed up if you leave it off for awhile ?

 

[yafatana]

but the motherboard is new
I bought it just 2 days ago
how can it come with a dead cmos battery ??

I had this problem in Windows 8 and if I recall correctly it was fixed by deselecting the “Turn on fast startup” power setting.

Control Panel -> Hardware & Sound -> Power Options -> Choose what the power button does (System Settings)

Memory timings?
no, that would throw a code..
Hmm, temps ok?

Did you connect the front panel connectors properly positive/negative?

Did you make sure there are no standoffs poking the mobo in the back?

Did you connect the PSU properly - firmly plugged in?

Latest BIOS?

Any overclock?

Could you have power on by keyboard set and your keyboard is misbehaving?

Chock start is common on Gigabyte motherboard's sense X38, others do it also when overclocked. Could also be a sign of a bad over clock, the board reaches out to see what it has on it. Then if it see's something not right it will chock start, and try again.

My Asrock X58 Extreme6 does that when I overclock it. If it's not overclocked it will do a warm reboot (no shutdown) but once you kick it out of spec with an oc it does the complete shutdown/restart on a reboot.

Maybe yours is similar?

If some of my front panel connectors connected to the motherboard wrong way like positive in negative and negative in positive any harm done to the motherboard----------also I'm not overclock also that proplem does not happen all of the time .

Yes, the BIOS is checking to see that the overclock is working okay, I believe.

That's the reason for the short shutdown.
