I've followed absolutely every single tutorial I could find and nothing is working. It's an intel i7 12700k on an ASUS TUF Gaming B660 11/12th gen intel WiFi DDR4 MB + 2x8Gb corsair vengeance RAM + IDCooling Liquid Cooler + Zotac 3060ti + LG 24in 165hz monitor + evga 750w power supply. The motherboard LEDs turn on, but absolutely nothing else turns on. I've checked the monitor's performance and it does work, but not with the new system. I'm almost certain that it's the PSU Cables that I'm having trouble with, but it could be something else. I can provide video/images of the setup in about 7-8 hours since I am out of the house right now. Thanks sm 🙏 (parts in pic minus monitor and case)

Does the motherboard need a bios update by chance?

how would i do that without turning on the pc? i can't get anything to show up on the monitor from any source. the only thing that shows up is the monitor's interface and that shows up when i plug it into the wall only

Some motherboards have flashback to flash the bios using a USB stick so yeah. that' is an idea. Check if this motherboard needs it and if it came out of the box with an BIOS which runs your I7 1700K

hard harbor i'll try to do that when i get home, thanks

regarding build, its a entirely new build?

hard harbor Jan 20, 2023, 6:19 PM

yep 👍

Did you double check all the cables? Double checked if all the cables are on the PC?

#

Motherboard has the 24 pin, SSD has its own power ( NVME is screwed in ) Ram has been seated in the right slots? (see your motherboard book)

#

Motherboard also has its 8 PIN cable attached? (just touching all bases)

hard harbor Jan 20, 2023, 6:20 PM

#

yep, all plugged in, but i'll double check the SSD when i'm home since it's under a heatsink and a pain to access

#

Also is the ram in the right slots? (see your motherboard manual)

#

if you got 4 , its fine, and should work

hard harbor Jan 20, 2023, 6:20 PM

#

yep, they are (2x8)

bleak lotus Jan 20, 2023, 6:21 PM

#

so you added them in slot #2 and #4? 😮

hard harbor Jan 20, 2023, 6:21 PM

#

yes i did

bleak lotus Jan 20, 2023, 6:21 PM

#

skipping closest to the CPU.

hard harbor Jan 20, 2023, 6:22 PM

#

mhm 👍

#

i read the manual like 4 times in between to make sure everything was right whoa

bleak lotus Jan 20, 2023, 6:22 PM

#

Thats good! Any beeps at all?

#

and did the GPU monitor cable attach to the GPU (and not the motherboard?)

#

Cable of the monitor should be in the GPU and not in the Onboard Graphics Outputs.

#

bleak lotus and did the GPU monitor cable attach to the GPU (and not the motherboard?)

yep, it is connected to the GPU ports. i tried an HDMI cable and a DP cable, neither showed anything

#

sorry about leaving for like an hour i had a class

bleak lotus Jan 20, 2023, 7:08 PM

#

No beeps or anything?

hard harbor Jan 20, 2023, 7:09 PM

#

nope, just the default monitor sound when its plugged into the wall. the mb LEDs light up rainbow and cycle though

#

did you try booting with 1 Dimm? on the 2nd slot , if one of them not working try the other.

#

If that ain't working, you have to wonder which component is not working 🤔

#

Since the BIOS should work for said 12700K, normally I would say update bios.

hard harbor Jan 20, 2023, 7:53 PM

#

alright, thanks. i'll try booting in 2nd slot
