[Solved] Motherboard won't boot after installing graphics card, EVEN after reverting build. Please help, any ideas?

[nowayhaze]

Hello, I'm currently finishing up a build with a graphics card. Because of the current market, I had been using Intel integrated graphics for about 6 weeks now with my build, no problem. Recently, I snagged a EVGA GTX 1060 SSC 6 GB for a good price, so I was so ecstatic to finish my build once in for all!
(complete parts list below)

However, I ran into some serious trouble. I installed the 1060 into my PCI-E slot. Then booted up my machine (still case open) to test it. And everything lit up, including the 1060 LED. I went to get my monitor HDMI to start connecting peripherals to my computer, and around this time I think heard the CPU fan speeding up, and then within a few seconds, the computer turned off.

Okay, I thought this was weird, so I tried turning the computer on again. No dice.
Then I thought maybe it was the front panel power button, so I unplugged it and nothing happened when I shorted the two power pins.

Now, I was in full-blown troubleshooting mode: time to take out the 1060 and revert my build to the IGP state (everything below except for the 1060).

Sadly, the computer will not turn on. Not a peep. Even after removing all but one RAM stick, and taking the motherboard off the stand offs with the minimal build. Nothing.

I even checked my EVGA G3 PSU with the 24-pin checker thingy and the PSU fan seems to turn on fine by itself.

I'm extremely frustrated right now, and I think I may have shorted my motherboard (or even CPU!) permanently. What do you guys think? Any other explanations?

My build is below (I tested this build for 6 weeks without the GTX 1060). Thank you for reading my posts, any fresh ideas or questions are welcome!

try using the clear cmos jumper if the card was bad/damaged from shipping it may have turned on the dead short protection. take a look at the gpu make sure none of the caps are missing from shipping damage.

I tried clearing the CMOS. No luck. The graphics card seems to be fine.

Okay, so the motherboard was completely dead, no lights or any sound.
I ended up RMAing my motherboard to Gigabyte. They exchanged it for a completely new one, and now everything works! Thanks!
