please help, new pc not working

[SirStaples]

Over the holidays I built my first pc. It ran completely fine for a few days and I was really enjoying it. Then yesterday I restarted it to go into the bios to do bios things. It shut down completely fine but didn’t boot back up. It won’t turn on when I press the power button. I’ve checked all of the connections of cables and nothing is working. Has anyone had this happen to them or know any solution to this? I have a warranty on everything if I need to replace any parts. Which part(s) would need replacing if so?

 

Thanks

Right the first thing to do is unplug everything apart from mother board 24pin cpu and pci power so no drives or RGB and short the power button pins try that

Just take out the cmos battery and clear cmos, i think on newer boards its a button instead of a jumper, and im also not sure if the battery needs to be removed or not

Thanks for these responses, I’ve tried both of these leading me to believe that it’s the power supply that isn’t working. I’ve ordered a replacement and hopefully it works.
