Hi

I have a crosshair vii hero with a ryzen 2700x, 5700xt gpu, 4x8gb gskill ram and 2x nvme ssds and i am running a fresh win10 (installed a week ago). Today all of a sudden i cant get my pc to turn on! I dont mean that it doesnt boot, i mean its like it doesnt have power and i tested it with 2 PSUs that both work OK on a different pc.

A bit of history on the problem: I have this rig for over 3 years now so its not new but it was working great until today without any warning signs of a problem.
Today i was playing a game when suddenly the pc crashed. This is rare but it does happen to me from time to time.
I rebooted and i realized that windows suddenly doesnt recognize my second nvme disk (the one that had the game i was playing on). This is a new disk i installed 3 days ago. So i shut down my pc normally and i remove and reinstall the nvme. After that the pc never turned back on again!

I tried everything i can think of. I removed the motherboard from my case, removed everything from it including both nvme disks and left only the cpu and 1 ram stick and it still wont start.
When i hook it up to the PSU the "start" button led on the mobo turns on as usual and so does the reset bios led on the IO panel at the back but when i push the button nothing happens, the PSU doesnt turn on and neither does the mobo.

At this point I am pretty sure the mobo is "fried" even though it had no reason to. I did inspect it thoroughly and it has no signs of physical damage or burnt components.
Has anyone else has had this problem or or does anybody have any ideas on what else i should try?!
