My specs:

NZXT H440 case
Corsair RM750 power supply
Asus H170 pro gaming Motherboard
Patriot Viper Elite Series DDR4 16GB (2 x 8GB) 3000MHz
EVGA GeForce GTX 960 Super Clocked ACX 2.0 4GB GDDR5
Core I5-6500 (stock cooler)
Samsung 850 EVO - 500GB SSD

When I woke up this morning, got my coffee and wiggled my mouse waiting for the monitor to turn on, nothing. Realized the case power light wasn't on. So I thought, okay, maybe I lost power in the night. I tend to leave it running 24/7. I press the power button on the case, nothing happens.

I unplug the power cable, try again in an attempt to discharge the psu. That is something I had to do at times on my older system on occasion, with my Corsair TX650 psu. No change, wouldn't power on.

That said the motherboard has stupid red 'breathing' LEDs which when I plugged it back in lit up (they were lit up earlier as well). So its obviously getting some power. Next step I unplug the power connectors from the motherboard and test the psu (green wire to ground) and the psu turns on, case lights up, fans run.

After that I unplugged all peripherals, nothing, remove the video card, same. Then I removed one of my ram sticks, nothing. Tried swapping them and tried different slots. All nothing. At this point if it was ram I would expect the to see the system at least trying to start (cpu fan twitch).

I don't have a pc speaker so I can't get error tones. Neither the case or MB has a damn pc speaker (unless i missed something). I do have a lot of older computers around so I should be able to connect a speaker, that's next on my to do list on testing.

Now maybe I shouldn't have done this (though its worked in the past) but I forced the psu on with a paperclip just as I tested it earlier but this time connected to the motherboard, the cpu fan kicked in but no visual/post from the monitor.

I'm flying blind without post error codes but I'm assuming a damaged motherboard. I have had this system for a few months and its been working fine.

Is it a safe bet the MB is damaged or what? I am new to skylake. I'm writing this on my old AMD Phenom II x4 955 black.

Well, I feel like an idiot. All I had to do was clear the CMOS. I couldn't find the jumper to start so I pulled the battery, went through the manual and finally found the jumper to short so that and or leaving the battery out for over10 mins fixed it. Booted like a charm.

Hopefully someone can learn from my mistake
