[SOLVED] Motherboard lights up, but doesn't turn on. Advise?

[m.shopping0025]

Hi People, 

In the last months, I have been building this ultra Video-editing and gaming PC with the following specs:



CORSAIR GRAPHITE SERIES™ 780T FULL TOWER CASE
Intel® Core™  i9-7980XE

Gigabyte X299 AORUS Gaming 7 Intel Socket 2066

128GB CORSAIR VENGEANCE 3000MHZ

11GB nVidia GEFORCE GTX 1080 Ti - still on the way

4TB SEAGATE FIRECUDA SSHD

512GB WD Black M.2 NVMe PCIe SSD

32 GB Intel Optane Memory

16X BLU-RAY RE-WRITER DRIVE

INTERNAL 52 IN 1 MEMORY CARD READER

CORSAIR 1200W HX Series Modular 80 Plus Platinium

Corsair H1155i PRO Cooler w/ PCS Liquid Series Ultra Quiet Fans
ASUS STRIX Raid DLX 7.1 PCIe

ASUS PCE-AC88 AC3100 2100Mbps/5 GHz

 

I am still waiting for the video card, but since I knew it's going to take ages to put everything together, I decided to install everything I've got except the video card thinking I can install it at a later point. 



So, I've put all the parts mentioned above together, as described in the manuals and as guided by tutorials on the internet. But when I wanted to test if it turns on, something very odd happened. When I turn the PSU on,  the LEDs on the motherboard lights up for a second and nothing else happens. Also when I press the main power button, a very bizarre squeaky sound comes from the CPU as you can see in the following video:

Did any of you encounter this before? Or at least do you have any idea what it can be???



Also, I took a few photos of the motherboard and CPU install I've done.

Help, please??

CPU can't produce sound of itself. The sound reminds of coil whine, is more likely to origin in PSU (or less possible a faulty fan).

Hi Grobe, Thanks for your reply.

I've tried to remove components and see what happens. However, I can't figure it if it's the motherboard or the PSU. Any advice how could I test that, considering I don't have spare ones?
Thanks.

Short answer : If you manage to jumpstart the PSU, then the sound will either be present or not. But also possible (if it origins from psu) that it require some load in order for the sound to become auditible.
