Computer wont turn on even after replacing psu and motherboard.

[LinxIsntHere]

My computer wont turn on. Now ive tried to fix it by getting a new psu, my first suspect to the problem. I bought a new psu, and it didnt turn on my pc.
"Okay" I thought. So I sent back the psu, and instead got a new motherboard battery, doesnt work. Today I find my computer, STILL doesnt work even after installing a brand new motherboard. Tried the paper clip test on the old psu, fan turns on. So what gives?

Computer Case Power button broken?

have you tried to use a paperclip/screw driver on the two pins which are for the POWER button on your motherboard? (to bypass power switch)

Do you have the LED lit up on the motherboard
