PC rebooting itself

[ubuysa]

I can see the restart in the system log...

...but there is nothing to indicate why. That's usually indicative of a hardware cause, or a cause that the Windows error recovery routines aren't able to catch.

You still have two different copies of amdkmdag.sys installed...

...which really doesn't look right to me.

I now think that, despite the difficulty and inconvenience it's going to cause you, that we have to prove whether this issue is related to that Radeon 580 card or driver. The only way to do that is to uninstall the driver with DDU and then remove the Radeon 580 card and just use the iGPU. I appreciate that the problem is random, but it does seem to happen within a couple of days and, from what you said in your OP, it seems to happen whatever you're doing. I think that if you can stand to run the PC without the Radeon 580 and driver for four days without getting a black screen and/or restart then we could be confident that the cause is related to that 580 card or driver.

Of course, if you do get a black screen and/or restart without the card then we're looking in the wrong place. If this happens please run the Sysnative file collection app again and upload the new output.

BTW. There is also an error with a generic USB hub, this is almost certainly a motherboard hub, but the error may well relate to a USB device rather than the hub...

Generic SuperSpeed USB Hub    USB\VID_05E3&PID_0616\6&1B2B7D3C&0&4    This device cannot start.

It would be wise to unplug all USB devices that you don't absolutely need and see whether that has an impact on the restarts.

Thanks. I'll give this a go. At least I can have 2 screens on the integrated graphics, so its not like I'm going back to just 1 screen

is there a way I can see this without running Sysnative?

If I look in those 2 folders, I can see 2 .inf files - which have different versions in:

Those are the ones, perhaps you do need them both? That sounds odd though...

We'll know more if it restarts without the 580 card.

I'm going away for a few days now - but will give the card disabling a go tomorrow. I'm guessing just disconnecting the power cable should be enough? (its a bit of a faff getting the card in and out due to the size of it!)

 

[ubuysa]

It would be a much more reliable test if the card was removed - and the driver uninstalled (via DDU). It's important that we have confidence that the 580 is definitely not involved. It can still draw power and communicate via the PCIe lanes if you leave it in. Troubleshooting is often painful, sorry.

Take your time removing it, and remember there may be a latch down by the PCIe slot. Don't break anything in your eagerness to get it out. I've been there and done that!

 

[youradds]

I've removed the card physically now. Also, run DDU. I still see this in device manager:

Is this from the iGPU?

 

[ubuysa]

Yes.

 

[youradds]

Ok cool. I'll see how this goes for the next few days. If it reboots in that time, I'll do a Sysnative dump and upload it

 

[youradds]

It hasn't crashed yet in the last 48 hours. So, I guess it is possible it's the GFX card. It was working fine in my old machine, so its a bit odd if that is the case

 

[ubuysa]

If you still have the old PC does the card still work in there?

At least you've confirmed what the problem is.

 

[youradds]

I do have it - but its a bit of a faff testing it, as it means I need to take the PSU cable from the new machine, and put it back in there (and this case isn't very easy to get into the PSU stuff without dismantling a chunk of the case :/)

 

[ubuysa]

Buy another cable, they're readily available and not expensive. It would be good to know whether the card works in the old PC because, if it does, you can sell it on as a working card.

I just had an afterthought. I wonder whether the problem could be the extra power cable? Is it fully home at both ends? Maybe not if it was awkward to get in. TBH If you do replace the card I would replace that power cable too.

 

[youradds]

I've ordered a new cable (only a £12 one - hopefully its up to the job). Will give the card a go on the old machine when that arrives tomorrow

Is it fully home at both ends? Maybe not if it was awkward to get in.

By fully home, you mean clicked in? I believe so (its a bit of a weird cable, in that you have the 6+2 - not sure why they don't just have 8 on one?). What I ended up doing whe putting it in, was take out one of the other cables on the PSU when fitting the new one, and then put it back in after (you can't reach behind). I guess another option is to unscrew the PSU and slide it out so I get more access to it

You can’t just get any cable, it has to be the right one for your specific PSU model by the way

6+2 is normal for pcie as some gpus only require 6 pins

 

[youradds]

Interesting. I just assumed any cable would do it? I obviously moved the cable from my old PC to the new one. This is the one I ordered:

HABAGOU PCIE Cable for Corsair, 65cm(26inch) PSU 8 Pin to 6+2 Pin PCIE Power Cable for Thermaltake, Male to Male Modular GPU Cable for ARESGAME https://amzn.eu/d/7X0LYQk

The PSU in the new machine is: CORSAIR 850W RMx SERIES™ MODULAR 80 PLUS® GOLD, ULTRA QUIET

The original PSU I had in my old PC was the CORSAIR 550W VS SERIES™ VS-550 POWER SUPPLY , but I upgraded that to a 650 I believe when I put in the new gfx card . Could that be the issue? Maybe it needs a different cable?

 

[TonyCarter]

I think your PSUs all use Corsair Type 3/4 cables, so it shouldn't be an issue - the only difference between T3 and T4 was the pinout on the 24-pin ATX socket.

It just did a reboot on me - so may not be the card after all. Just running Sysnative now and will upload the files once its completed

ok here is the dump file: https://drive.google.com/file/d/1KPhyeHy2YfYbOKq1Jm2xTvcbki-Tq97n/view?usp=drive_link

Hopefully it has something helpful, as its getting a bit stressful with these reboots. I just lost 30 minutes worth of work that I'd done (I can't autosave, as its to a live website so could introduce bugs)
