Male sure all of your cables are plugged in correctly. Sharing your specs would be a good start, we arent magicians. Try booting with 1 stick of ram first, and make sure its actually in the slot correctly

You need to copy paste the code in the box not the url in your browser.

No red flags I can see looks like something might have been DOA.

Film your debug codes and post them here, also remember to follow your topics @Supreetd

You have the motherboard on the standoffs right, if your motherboard isnt, it will stop itself from turning on to protect itself.

Use a multimeter to test the psu. My guess is it is the problem. Before doing that though make sure everything from the psu to the motherboard and video card are connected properly.  Make sure you haven't missed connecting anything.  Is the cpu fan connected to the motherboard btw? Leave the case side off and see if all fans spin.

Never heard of this in my life, you can power on a motherboard on the back of a camel and it wouldn't be able to notice.

push in your 24 pin and try turning it on while pushing it in.

 

happens with mine whenever i bump it (my psu can't lock. dont want to go thru rma)

I actually had the problem myself, I had the motherboard touching part of the computer case and it was stopping itself from turning on. Took it off and put in the extra standoffs and it booted perfectly. The standoffs ground the motherboard so it doesn't short out.

Might be ram I had a issue similar with faulty ram

The standoffs serve no purpose of grounding it, you most likely had a short on the PCB because it was laying on a conductive surface.

All the wires are pluged in and only the CPU fan turns on other fans doesn't

Try using only one stick of ram and no gpu, and no wifi card.
