Whea_uncorrectable_error (124)

ppaterso · 22 Nov 2018

Hi All,

I have seen three or four blue screens on a clients computer and have only just managed to grab the dump file before it disappears. I have submitted the file to osronline and have attached the analysis.

The bit that confuses me is that it mentions a fatal hardware error but also mentions a win8_driver_fault.

If somebody with a better debug brain than me can look at the attached and point me in the right direction I would be most grateful

Cheers all.

Apologies - my mistake. Correct files attached.

Thanks all.

Very similar to this: http://www.tomshardware.com/answers/...le-inside.html

The concern is focused mainly on power. Check BIOS and look at the voltages of the PSU, see if they are close to the nominal values and see if they are fairly steady. Also check temps using HWMonitor.

Also can you provide the specs for the clients computer?

ppaterso · 26 Nov 2018

Thank you. I’ve attached a PDF of the spec.

It’s still in warranty so I’ll probably go to Dell and get them to sort it. I just like to understand what’s going on so they don’t pull the wool over my eyes.

Ztruker · 26 Nov 2018

All-In-One systems are notorious for heating problems so definitely check temps with HWMonitor.

Good idea to let Dell sort it out though. Gorgeous looking computer. 24" Infinity edge screen.

ppaterso · 26 Nov 2018

Cheers for your help Rich. Much appreciated. My client has another one that just appears to go to sleep (even though all sleep options are turned off) and it has to be power cycled to recover - no response to keyboard or mouse and network connection is dead. Power light is still on though. If it produces a crash dump I’ll upload that to a new thread. Not sure if it will though as it doesn’t ‘officially’ crash.

@zbook, what are your thoughts on this? Power, heat, device driver or a real CPU fail?

zbook · 26 Nov 2018

1) There were multiple APIC ID: 0, 1, 2, 3 displayed in the logs.

2) The temperatures can be monitored with: Speecy, HW monitor, Speed fan:

b) HWMONITOR | Softwares | CPUID: HWMONITOR | Softwares | CPUID

c) SpeedFan - Access temperature sensor in your computer: SpeedFan - Access temperature sensor in your computer

3) Tests that can report confirmatory or additional information are:

a) Intel Processor Diagnostic Tool (IPDT)
