Hello all,

I'm having an issue with the computer where it will shutdown randomly. It's never happened when I'm actually using it (i.e sat at the desk) however, I've left to cook dinner and come back to it being off. When I open the Event Viewer and look at system I can see an error with a message "The previous system shutdown at 21:52:34 on ‎22/‎06/‎2025 was unexpected" It's only started happening the last 2-3 weeks and I cannot for the life of me figure out why.. there has been no component changes from when I first built the PC (End of 2024)

I've checked the power management settings just to make sure it's not set to turn off after a certain time etc. When it does shut down, I can't just simply press the on button and it comes back on, I need to flick the power switch on the back of the computer and wait 2-3 mins before it'll fire back up. I have checked all connectors to the PSU/Motherboard etc.

Spec is as follows:

CPU - AMD Ryzen 7 9800x3D
GPU - RTX3070
PSU - Corsair RM1000e Fully Modular ATX Power Supply - ATX 3.1 & PCIe 5.1 Compliant - 105°C-Rated Capacitors - 80 PLUS Gold Efficiency - Modern Standby Support
Motherboard - Asus TUF Gaming X870 Plus
Plenty of cooling, has x8 fans and an AIO CPU Cooler

Thanks in advance for any help :)
 
It's just happened again, this time whilst I was using the computer. In event viewer the last action that happened was "Mtkwcx" - Scan abort. I've noticed this event a few times now, is this anything to be concered about? I've but the ram back to standard clock settings as well as the CPU. temps all seemed fine before it turned off though. I am UK based, as yes there has been a heatwave but it's only 18 degrees now, and I haven't been on the computer when it's been hot.
 
I'll restart and turn off the wifi, I've downloaded that and it shows this https://imgur.com/BC5tQQM

**Edit - I'm stupid, I can't turn off the wifi as I'm using wifi (Duh) I used to use an ethernet cable but where the computer is now I need to use wifi.**

Ok, I have turned the WiFi off via disabling the WiFi controller in the bios. It’s getting late here in the UK so it’s bed time for me, I’ll leave my computer on and report back in the morning… fingers crossed it’s still on! Thanks for your help so far
 
So no joy with the above, computer had turned off, i turned it back on and decided I would try to clean wipe the computer with a fresh windows install just to make sure it’s not software/virus causing it to shut down. As soon as the re install finished it shut down again.
 
Yes I think so too, I’ve been reading a few horror stories about the Corsair RM1000E PSU shutting down a lot, should’ve gone for the RMX
 
So I’ve unplugged all USB apart from the mouse, with no joy stayed in for about an hour and now off again.

I built the PC in January and haven’t changed any components at all. I have checked all cables are correctly installed and made sure the PSU fan was working correctly which it is.

I’ll test ram sticks now by using one and then the other.

I’ve not updated the bios and to be honest I’m not sure how so I’ll have to watch a video.

I’ll download the stuff to tests the storage drives.

I haven’t tried without the GPU, do I simply just unplug it and it will automatically use the AMD cpu graphics or do I need to change settings first before I unplug?

Thanks
 
So, I've now had it on for close to 4 hours with no issues. Currently the GPU is unplugged, one RAM stick and also only using 1 monitor (as Motherboard only has 1 HDMI output) so I guess it's going to GPU which would be a bummer as I can't afford a new one, but I'll chuck it back in and see what happens
 
it seems stable, but to be on the safe side I'll not do anything for a few more hours, maybe even until tomorrow and just leave the PC on so I can be confident it's not going to happen again
 
So, the computer was on and running fine for over 24 hours. No random shut offs etc. I have put the GPU back in, and within 2 hours it had shut itself down, wouldn't start up again until I've flicked the switch off on the PSU, waited for about 30 seconds and then flicked it back on. When I turned it back on, i was greeted with a "bitlocker" screen, where I had to input a code from Microsoft to get access to the computer again. Would the next step just be changing out components? Is there a way I can check if my PSU is strong enough to be running the system? I assume a 1000w would be, but I guess it's worth checking now.
 
Unfortunately the GPU is the only part that wasn’t new in the system, I’ve had that for a few years so an RMA won’t happen - I’ve been after an upgrade so maybe it’s time to bite the bullet and do it
 
I see, I’ll pick one of those up and see if I have any joy with that, at least it’ll narrow it down a little more if it carries on when that card is in….
 
So I have now fit the RTX 5070ti and completed a full re-instal of windows and the computer (so far) has not shut down! It's been about 3 days now so hopefully that issue has resolved itself! I have noticed since the re-install though two things, sometimes I get an error and I'm greeted by a blue screen with error code 0xc000000e Error - Your PC/Device needs to repaired hoping maybe sfc in CMD can sort this but will try once I'm home. The other thing which may well be because of that issue but the boot up process is very slow now. It used to turn onto the login screen very quick, now it takes a good 30 seconds or so.
