Hi,

I am building a new PC using the following components:

ASRock Motherboard Z270 Gaming K4
Intel 7th Gen Intel Core Desktop Processor i7-7700K
Corsair Vengeance LED 16GB (2x8GB) DDR4 3200 (PC4-25600)
Crucial MX300 1TB SATA 2.5 Inch Internal Solid State Drive
Corsair Hydro Series H80i v2 Extreme Performance Liquid CPU Cooler
Corsair RMx Series, RM650x, 650W, Fully Modular Power Supply

No graphics card yet ... planning to use integrated graphics
till system boots up and windows installed.

I got all components installed/connected but when I power up, no video
output thru on-board HDMI. Motherboard red LED keeps blinking, all fans
working, PSU is on, no beep. I have checked the following:

1. RAM seated properly and installed in A2 and B2 slots
2. 24-pin and 8-pin 12V ATX power connectors are connected properly
3. CPU seated properly
4. Corsair cooler pump connected to water pump fan connector, 2x radiator fan connected to CPU fan connector
5. Case fans connected correctly
6. SSD sata connected to SATA0 and power
7. Double check system panel headers (power/reset button, HHD led, power led)
8. Audio header connected

Connected to my working monitor (used in my other PC, temporarily disconnected to setup new PC build). I tried HDMI and DisplayPort but no output on both (No signal displayed on monitor). I also
tried it on a working TV using HDMI and same issue is observed.

I have searched the internet for solutions but so far none worked, problem persists. I even tried
taking out (and back in) the CMOS battery and even clear CMOS.

Anybody experienced similar/same issue and have fix? Any help will be very much appreciated.

Update:

After trying everything and no solution, I decided to get
another motherboard (ASRock Z270 Gaming K6). Re-installed
everything and this time it worked ... no issues at all. I guess
I got a defective ASRock K4 motherboard.


Thanks,
Rolando
