Why doesn't the bios show up and are any of my parts broken?

I'm currently experiencing some issues with my pc right now and I'm not sure which parts are the problem nor what the problem is.

At the start, I had some problems turning it on but now that I had it on, it didn't turn on-off when the power button is held and only stopped the GPU fans from moving(led is on and other fans such as CPU fan case fan are still moving) but quickly turned on again after releasing the power button. Eventually, I turned it off by switching the power supply switch.

It also won't show the bios and the monitor remains at a blank state showing nothing, not even the manufacturer of my motherboard's logo. Tried to see what was wrong inside and checked if I missed anything to plug but everything seems to be plugged so I assumed it was a problem with the motherboard. The motherboard lights up too but I'm not sure if that's the problem either.

Currently planning on removing the parts individually and rebuilding it with my dad. If you guys can help me figure out what I messed up during my build and tell me if any of my parts seem to be the problem then I'd be very very grateful.

If it's necessary to shut down using the power button, simply press the button & hold it until the system completely shuts down.

If you have fast boot enabled & the system boots too quickly to enter the BIOS, completely shut down the computer, open the case & temporarily disconnect the SSD & HDD, then power up again. Without the drives connected, you'll have no problem getting to the BIOS.

According CPU specs the DDR4 is up to 2933MHz. Did you overclock to 3200?
As already mentioned, disconnect drives from MB, remove all external connected devices,
If possible remove GPU (onboard GPU?)
Use one stick DDR4.(switch to other DDR4 stick if still unstable)
Any improvement in stability?
At startup should complain about missing drives and enter BIOS

If stable, reassemble piece by peace and check stability before adding
