Hi,

My ROG STRIX B250F GAMING indicates red light (bottom right corner) and it doesn't boot up. The lights near 24 pin light up and my nvidia GPU indicate white light but the centre CPU area and my RAM does't light up.

Motherboard: Asus ROG STRIX B250-F Gaming
CPU: Intel Core i5-8400 LGA 1151
RAM: G.SKILL TRIDENT Z RGB 16GB ( 2 X 8 GB ) DDR4 3000MHZ
GPU: ASUS GeForce GTX 1050 Ti 4GB ROG STRIX
CPU cooling: Thermaltake Water 3.0 360 ARGB Sync Edition

I have remove and place the ram and check the power connection but it does't solve the red light issue.

please help me solve this issue
 
Solution
B250 wont work on i5-8400 as it only support 300 series chipsets,
and there goes your red boot LED (indicating CPU issue).

You need a 300 series board (e.g. B360) to get it running.
