Hi Guys I know this is a commonly asked question but just wanted to know how to fix it (Very New to PC Building) - I have built my PC plugged in all the necessary cables, installed 2 sticks of 8gb DDR4 ram below are the parts I picked.

/Parts\


-D-Link DWA-548 Wireless N300 PCIe Desktop Adapter

-Phanteks Eclipse P300 Tempered Glass Black

-Seagate FireCuda ST1000LX015 1TB SSHD

-Thermaltake Litepower Gen2 750W Power Supply

-CableMod 3-Pin Fan to 3x 3-Pin Fan Adapter Black

-Corsair Air Series SP120 Blue LED Fan Twin Pack

-be quiet! Pure Rock CPU Cooler

-MSI H110M Gaming Motherboard

-MSI GeForce GTX 1060 OC 6GB

-Kingston HyperX Fury HX424C15FW2K2/16 16GB (2x8GB) DDR4 White


/Problem\
The PC turns on all the fans kick into action the RGB on the fans turn on, the Graphics Card starts to spin and any other extra fans (Including CPU Cooler) all start to spin. Then it all turns off this all happens in about 5-8 second - I should also mention a red debug light flashes when the CPU turns on this is shown on the motherboard. I have also hooked up a HDMI cable to a monitor to see if i can get any signal but no signal is found.
I have rebuilt the entire PC twice to make sure i haven't forgot anything and have used anti-static mats to make sure not to fry anything.

Thankyou

 
Solution
You need a supported CPU to update the bios unfortunately.

The only way to fix the issue is to buy or borrow a 6th gen skylake cpu, update the bios, and then put your kabylake cpu back in it.
As stated, you cant put a 7th gen CPU in an H110m wihtout a bios update (which you often cant do without a supported CPU).

Other likely issue is you forgot to plug in the 4pin/8pin CPU cable from PSU to top of motherboard. That will cause that on/off problem that you have.

Hey guys thanks for the answers - yes i have remembered to plug in the 4 pin CPU cable from the PSU at the top of my motherboard and made sure that it clicks into place.
Furthermore how do I update the bios if doesn't even get a signal or turn on.
