ASUS PRIME Z270-A won’t boot up

[Yossi1114]

My PC doesn’t start running. No fan spinning. I only see the PWR_LED shows a green light. I think it should be working since all lights are green and there’s no red or orange light. Tried CMOS reset and removed its battery for a little while but no success. Also removed all PCIe cards and unplugged the power cables for storages.

Also to make sure the motherboard isn’t dead, I have removed the memory to check whether the board beeps properly or not. There’s no beep after all, and the lights are still green.
 

• ASUS PRIME Z270-A
• Intel Core i7-7700K
• Silverstone 1200W 80PLUS Silver

I’ve read the guide here ( https://forums.tomshardware.com/faq/no-post-system-wont-boot-and-no-video-output-troubleshooting-checklist.1575220/ ) and have followed the instructions.

I need your help. Thanks

Check the pins on the cpu and the motherboard... do you have warrenty?

Have you tried using the surface mounted power switch on your board? Judging by the pictures, you have one located just above your 24 pin.

Exactly. Of course, I have tried that one but resulted in the same.

Checked all the pins carefully and could not confirm even the single bent pin. This build was working 2 days ago and today it suddenly turned not working. Will see if it is still eligible for applying RMA.

 

Thanks for the advice! If you still have any ideas, please feel free to post your comment here. I extremely need your help.

UPDATE: I have filled the RMA application form and sent it to the authorized local seller (not ASUS official) but they refused to repair/replace the motherboard for free even though the warranty is still eligible according to the product page on ASUS official website. Trying to figure out what to do.
