I have been putting this machine together over several days as I get components in. It was working great, I plugged everything in (except for the SSD) including RAM with it outside of the case. I upgraded the BIOS to F22 and set some settings. Then powered it down.

The Case I had didn't allow the 8-pin ATX plug to reach so I purchased an extension cable. My son got it in today and plugged it in and powered on the machine to see the BIOS screen to verify it powers on. Then he shut it down and left for work.

Later, he got the SSD out of its packaging and only plugged it into the power supply not realizing that it needed a SATA cable to the motherboard. He then texted me to say that he's only getting a blank screen and it won't boot. He had to force it off.

I took a look at it and the LED on the motherboard starts out flipping around and those 60 a few times, then it says 50 and then ultimately 55 and stops there. No video is displayed.

What happens after I pull power and try different options is that it will boot, "50" will show up on the LED, then it will shutdown and restart itself and then show 50 and a few seconds later show 55.

I tried re-seating the RAM, I tried moving it to different slots and only using one module. I also tried no RAM at all and with that the machine will turn on for 1 second and then power off and keep attempting to boot over and over.

The RAM is GEIL brand and it's on the compatibility list for the motherboard.

I unplugged the hard drive and tried resetting the CMOS and flipping switches on the motherboard to try different things and nothing is working.

People online said "bent pin" for the CPU but this CPU had no pins to bend, the CPU is a 2001-v3 socket Core i7-6800K that just had little dimples where it connected to the socket.


I can't think of what could have happened, it was working just fine.
 
Microcenter said I could return the motherboard even if it didn't work. Getting another one would be an additional $90 on top of what I have spent. :-( I just don't have the money.
 
Well, Gigabyte told me they would cross-ship a motherboard to me on RMA to see if the different motherboard would work. I waited three business days for them to get back to me and nobody did so on Saturday my son agreed to pay the difference on an ASRock Extreme 4 Motherboard and so I took this one back to Microcenter and purchased the other one.

I am happy to say after three days it is still functional with no problems.
