Possible dead X370 Taichi?

[teh_captain]

Hi guys,

I'll try and keep this short as I'm on mobile. Yesterday I was playing PUBG and my system totally shut off without warning. Tried to turn it back on again, nothing. The lights and fans spin up for a literal split second and they stop. No POST, no beeps, nothing. Smelt a little hot in my case, but couldn't pinpoint where from.

Tried the paperclip test on my PSU and it appears to be working. I have managed to try a spare PSU from a friend but the exact same thing is happening, I am getting nothing. Unfortunately I am the only person I know on Ryzen so I can't try a spare chip, although unless it's fried (I was going to take the AIO block off in a minute to see) surely the board would boot/beep if it was OK?

Aside from clear the CMOS etc is there anything else I can do? I was hoping it was a dead PSU but that doesn't seem to be the case unfortunately.

Cheers,
Tom

Well fiddle my bum and call me Sandra, it was the GPU all along! Plugged everything in one by one until it stopped turning on again. Unplugged the PCIE cables for the 1080 and I learned it had died an actual fiery death!

PCIE slot looks OK so now to call OcUK and see what's what. Cheers dude.
