Question Why isn't my new build turning on?

[lotaplota]

First build here (also first post on this forum. Hello!). All of the parts are brand new.

These are the parts:
Motherboard: ASUS TUF gaming B650M-PLUS mATX
CPU: AMD Ryzen 5 7600X
GPU: Nvidia Geforce RTX 3060 Ti 8GB
RAM: Corsair Vengeance DDR5 16GB 5200MHz
Power supply: Corsair CX750M
Storage: Netac 1TB 7400MB/s

The display doesn't turn on. I've tried connecting the monitor to both the HDMI port on the motherboard and on the one in the VGU.
There are 3 lights on the upper right corner of the motherboard. When I try to turn it on, one of them turn orange, then another one stays white for a while, then the CPU one stays red for a while and then the cycle restarts.
Because my cooler is a bit bulky, only one of the RAM slots are accessible, and it's the rightmost one. The RAM is plugged into that one.
I'm using the 8-pin cable of the power supply on the CPU. I've already tested with both the 8-pin and the 4-pin connected simmultaneously.
All the coolers are turning on effectively.
I've tried turning on the computer without the cooler for about 10 seconds. The CPU was getting warmer.

I'm really worried I'd have to update my BIOS. Some people say it can be quite risky.
Please don't judge me if I'm making rookie mistakes ;-; this is my first build and I've already learned a lot from it hahahaha
I'm also brazilian, so maybe I messed something up with my english. Feel free to ask me for clarification.
Any help is appreciated. Have a nice day!!

You mentioned both 8 and 4 pin power cables being connected to the motherboard. Do you also have the 24-pin connection firmly attached to the motherboard and PSU?

Yes. Very firmly.

Try removing the RTX 3060 and use the integrated video controller. When doing so, does anything ever show on your display?

I did that as well. Still nothing.

I would suggest removing the CPU cooler and then the CPU. Inspect the socket for damaged pins.

Did that. No damaged pins.
In fact, there are no pins. It's AM5. I found it so cool!

 

[COLGeek]

There are pins in the socket, not the CPU. Did you inspect those?

I hope there are actual pins on the socket for the motherboard...what is the make and model of your case? Did you try breadboarding the motherboard, processor and ram on the motherboard box?

mind sharing the color of the label on the PSU? Is it grey or green?

There are pins in the socket. They're ok.
What is breadboarding?
The cooler is a Montech metal DT24.
The color of the PSU label is green.

What is breadboarding?

its taking the motherboard out of the case and seeing if it will act any different by itself

Shame Asus don't let you update BIOS without need for a screen attached - https://dlcdnets.asus.com/pub/ASUS/...IOS_EM_WEB_EN.pdf?model=TUF GAMING B650M-PLUS

No... but now I think I should've done that.

 

[lotaplota]

I'm starting to think I'll need to update the bios using the bios flashback thing...

 

[Colif]

I don't see BIOS flashback in the manual. I see EZ Flash 3 which needs you to SEE bios to update
ANd I see Asus Crashfree BIOS but that just replaces the current one - I guess you could try this but I would contact Asus before flashing it, and see what they suggest. It could be you need to RMA the motherboard.

I flashed it!! It's working perfectly now!

 

[lotaplota]

Just asking just because. Did you use the standoffs between the motherboard and the case?
And if you did, did you put them all in the correct place?

I solved it! I've flashed the motherboard and now it's working! Thx for the help.
