New motherboard (GA-Z170X-GAMING GT) runs, boots up weird.
5 replies, posted
Only after disconnecting the PSU from the power, and starting it back up again, pressing the power button makes the computer start for a split second, then it shuts off for a second, then starts up again. It was telling me at some point that the BIOS settings failed and last known good defaults have been loaded, but I had since saved those settings and the message still doesn't come up. The system itself runs fine with flying colors. I even got it to boot up with the RAM overclocked by 600MHz.
If I only power down the MoBo without disconnecting the PSU, it starts fine. Should I be worried? Is this normal (because of two BIOSes or something)? What could it be? I don't have a speaker plugged in to the board, but I'm pretty sure that there's no beep code: that little surge time period seems to be too short for it to try and post. and return an error.
Thanks in advance.

Oh yeah, PSU is EVGA Supernova 850 G2.
I'm a bit confused. So the only time you're experiencing this is when the system has not been plugged in, and it does a quick failed start, then a full normal boot? If so this happens with some systems, nothing to worry about. The motherboard has a debug LED in the top right corner. When it does the split second boot, let me know what the last number it displays before shutting off is, if any.

Precisely. Once past the initial [weird] boot after plugging the PSU back in, the system starts up fine every time without error... until I unplug the PSU again :/
Yeah I've run into this a many times with systems, even on identical new builds. It's an oddity I haven't figured out, but haven't found it causing any harm.
The debug LED display doesn't have time to output anything comprehensible. It does a quick run of LEDs from ECO to the first digit, to the second digit, then turns off/on again.

Alright, thanks for the two cents. I guess I wont worry too much about it until I ask around/bring it back to Canada Computers. Also, the PSU has an 'Eco' mode. Could that be it?
I have a z170xp-sli and mine does this when it doesn't completely go past the bios. One way to test this is to boot the pc and quickly shut it down. I don't think it's an issue and at the wordt a minor inconvenience.
