Question Help with HP Omen 870-213w & boot

[7SinNerd]

A few years ago I bought myself a new computer in the form of the HP Omen 870-213w. Until a few days ago it has been nothing but great. Now I can't seem to get it to turn on. After some power of deduction, common sense, a bit of googling I thought it had to be the power supply. I've now replaced the power supply and still nothing. With the help of my dad we determined that power is in fact getting to the motherboard, and the switch (power button) appears to be in working condition.

Any advice on where to go from here would be very much appreciated!!

No power. Nothing turns on. Nothing runs. I'm starting to think it's the motherboard itself.

Nope. It was working fine the night before, then it just wouldn't start. We tried breakers, unplugging, etc. I even got a new power supply because I was convinced that was the issue.
