Hard power shut downs after a year of service

Darkly Spectre · August 28, 2019

So i just came back from my USA trip come home to my PC and nothing.

Specs.

2700x

Asus crosshair VII hero.

16 gigs of G.skill ddr4

The issue I am having is that now suddenly whenever I turn on the PC the case leds and fans twitch for a moment before shutting down. I cant even get to the bios screen.

This PC has been working perfectly fine for almost a year.

Sometimes it DOES post. Go through abit of it. Hard shut down again. Play this game several times until it just does instant shut downs. Sometimes it doesnt even do anything until i flip the psu switch. Sometimes I can into the bios and temps are fine and it doesnt crash in bios. Then sometimes it does get to the windows login screen. Work fine for a minute. Hard shut down.

Hell sometimes it works. It was working perfectly fine for a day. No issues. Games worked. General use worked. Came back to it this morning and once again it is instant shut down.

Things i have tried so far.

Clear CMOS.

Try using bios default settings.

Get rid of any usb devices incase of it being some weird shorting out usb.

Swear alot.

What psu do you have ?

You checked your internals before trying to boot first?

It looks like a watercooled PC, so you made sure no leaks first?

PSU is a corsair HX1000i.

Watercooling is dry. Checked the flow. Water is flowing since i first thought that it might be overheating shut down but temps are fine.

Left the power unplugged for a day to make sure. Nope. Wont boot. Just a single click from the psu and a twitch on the fans/flash of the LEDS

Disconnecting parts to see if anything is at fault. Ram, water pump and GPU power removal is doing nothing.

So took it apart. Took everything out except motherboard. Still clicking and dying. Ok. Plug in the jumper. Cant really tell since this thing doesnt spin its fan when on. Plug in pump. Pump runs. Freak out its the motherboard. Plug in motherboard. Works. Plug in cpu power. Works. Currently plugging the rest in. What the hell
