New build issue

Hi all

Have just built some his first pc and ran into a problem. Pc ran fine for a day and now it won't switch on at all. Have stripped it right back and can't find what's the fault.
The mobo is a asus tuf gaming a620m-plus wifi
PSU is MSI MAG A750GL 750W 80 Plus Gold ATX 3.0 PCIE5 Modular Power Supply

The mobo doesn't have a light indicator at all.so unsure if it's getting power. If I press the bios flashback button this lights up which to me indicates power but how can I be sure that I get the right part replaced. Don't have another PSU or mobo to be able to test either way which is a pain!

Any advice appreciated

That's what I thought, just not sure now to proceed. Do I rma PSU/mobo etc. got them from ocuk but not had to do this before so not sure what happens if their also not actually faulty as I got no way to verify one way or the other so feel kinda stuck

double check the power button is plugged in the right header, i had a pc i have to turn on with the reset switch lol

Yeah triple checked all this and it was working too and it suddenly turned off and since hasn't booted up so kinda lost now

pull the ram and try to power on. listen for clicks the smallest click can be a protection kicking in

Yeah tried this too and get absolutely nothing back from it

Just done the mobo flashback which appears to have completed as it stopped flashing but again it won't boot at all.
Attempted a jump start using power pins in case it's the power switch and nothing still
Just confused that if it's the psu surely I couldn't do the flashback to the bios?
And if it's the mobo why did it also appear to let me flash the bios!?

Full spec is a Ryzen 7600
Sapphire Radeon RX 7600 XT Gaming OC 16GB GDDR6 PCI-Express Graphics Card
Kingston NV2 1TB M.2 2280 NVMe Solid State Drive (SNV2S/1000G)
Asus TUF Gaming A620M-PLUS WIFI (Socket AM5) DDR5 Micro ATX Motherboard
MSI MAG A750GL 750W 80 Plus Gold ATX 3.0 PCIE5 Modular Power Supply
Kolink Observatory MX Mesh ARGB Midi Tower Case - White
Crucial Pro DDR5 RAM 32GB Kit (2x16GB) 6000MHz CL36, Overclocking Gaming Memory

Got nothing to be able to test with so ordered a new mobo last night from another supplier which is coming today just so I can test and hopefully rule one of these out!
I would have thought if it was a dead CPU etc then it would try and boot etc. I don't even get a power light when pressing the power button. Absolutely dead, no activity at all which makes me think mobo or PSU

No different board this time. Gone with an MSI model
Hopefully see some life later today! Thanks for all the help everyone - will update later
