Hi guys, I’m in a little bit of a pickle my system has been running fine for over a year now, a few days ago I got a graphics card not recognised error, which was sorted by removing and reinstalling the card, now my PC is just randomly shutting down, it can be while I’m gaming or even at idle, it has done it a few times while booting as well, I have done Stress tests on both the Graphics card and cpu and it’s never crashed while doing them. Anyone got any ideas where my problem could lie?

Download memtest and check memory errors .

After that setting everything to default and see if things are stable even though stress testing didn't cause an issue.

Yep I have already done that no errors and everything running at stock, which is why I’m leaning towards the board or gpu and the gpu lanes go from 16x to 8x to 4x

I'd try another PSU if you have one if it's just a split second shutdown. Perhaps your GPU not found error was really insufficient power to the card and the PSU is just intermittently faulty.

Strange thing is, it was working fine yesterday and the day before gaming all day and playing the same games as normal, and now today it’s started again, nothing has changed in the system, I have turned off automatic updates. The graphics card has dropped back to 8x from 16x again

I think your only way really is process of elimination.

I've had a faulty CPU in the past where the system would run perfectly fine when booted at any level of load, but intermittently the PC would just do an instant shutoff between POST and windows loading.

At first that problem was only occurring once every 3 months or so, but it got worse until it was every day when booting and then it wouldn't boot at all. Perhaps your issue will get worse too and become more apparent what's at fault but until then intermittent faults like this are a pain in the butt, especially if stress tests and the like don't kick it off.

Have you tried looking in your event viewer to see if there's any hardware faults getting logged?

Try running without your GPU, just use onboard graphics, I think the 7900x has that, right? That'd rule out the GPU if it still occurs. Obviously it's going to be annoying because you'll need to run a sufficient amount of days due to it being intermittent.

event viewer just shows Kernel-power as a critical event, if my house was cold I would start to think it’s a cold bug issue, it seems to be running fine again now, this has my head done in

Lockups, freezing and BSODs are usually caused by software, CPU, PCIe devices, memory and motherboard.

But the issue you are facing is complete shutdown which will only be PSU, PSU Cables or Mobo.

Yep its definitely not locking up, it first I thought it was my power tripping, that’s how it goes off, I was leaning toward the motherboard especially with the pcie dropping from 16x to 8 and then to 4x. I know whichever one I pick to replace it will be the other.
 
And speak of the devil it starts again, on thing I have noticed is when it does it, if I switch it straight back on it turns back off right a few times, before it even tries to go through its bios codes, and when it does finally get through the codes it switches back off before it gets to the boot screen.
the only thing that would allow me to get back to windows this time was removing and then reinstalling the graphics card

Last time I had something similar to this it went on for months, I was sure it was hardware. Ended up doing a fresh windows install which fixed it.

It would drive me nuts because the shut downs were so random, like you i could sometimes game for days fine then the next day it would shut down watching a youtube video.

i would unplug it and check the pci connector on the gpu for damager and or dirt, also check the socket for any dust etc, finally ddu the drivers and go from there, could be dust or even dirt or hair in the socket got in there when you took it out maybe

This is exactly whats happening, I’m currently restoring to a point last week, and then will remove and reinstall the drivers to see if that works
 
Well that didn’t work, I have just spent 10 mins trying to get past the bios check codes, for it to crash on the boot screen a few times, to get into windows to crash 2 mins into a game

edit now I can’t even get to the bios

New one now, try to power on and it it will get to checking the bios codes then off it goes, but I then have to switch the psu off to try again, the retry button on the motherboard is none responsive, the graphics card is out of the board and hdmi plugged into the board

Were you running some kind of non-stock setting? I know you said you were at stock earlier but perhaps something is unstable.

I was overclocked and running the memo at it’s rated speed, until all this started, now totally stock including the memory, I think I may have to bite the bullet and nuke my windows drive

I'm not convinced it's a software issue. It seems intermittent and the lack of crashing after rollbacks might be a fluke, after all the problem seems to come back?

I'd run a couple of days on totally stock settings now that you've cleared cmos and see what happens.

You could be right, as soon is I tried to run the memory at its rated speed by switching on xmp the shut offs and failed boots have stared again
