Question New built. System does not boot. Single Mobo flash.

[Rahul_rajvanshi]

I have the following config built recently :

1. Intel core i5 9600k
2. Mobo : Gigabyte b360 aorus gaming 3 WiFi (supports 9th Gen Intel processors)
3. Ram DDR4 2400Mhz
4. Antec a30 cooler
5. 240gb wd SSD
6. 1tb wd HDD
7. 450 w Corsair power supply

My system fails to boot up.
The Mobo lights flash once when the power is turned on and nothing else happens.
No other LED s turn on.

Troubleshooting steps carried out till now :

1. Checked for Mobo mount for unnecessary spacers -- looks good
2. Checked psu by shorting green and black wires -- psu works fine
3. Removed the Mobo and only powered it via 24 pin connector but still the same issue.

Can you please help me troubleshoot and fix the issue... ?

Possible problem is BIOS version, only 390 MBs come with 9xxx compatible BIOS version.

Do you know if the motherboard for sure supports 9th gen?

It may have an older bios revision that is incompatable with your cpu.

How can I check for the Bios version if I am unable to get through to the Bios screen... ?
Secondly the specs do mention the MB to be compatible with 9th gen processors...

A. Yes, the tech spec mentions it to be 9th gen compatible.
B. How can I check for the Bios version if I am unable to get through to the Bios screen... ?
