Have you noticed the constant BSODs and are you checking the same bug code daily?
Have you noticed the constant BSODs and are you checking the same bug code daily?
Hi all,
Since yesterday I’ve experienced five BSODs, each displaying the identical ‘239’ error code. Sometimes the system stalls, other times it shuts down instantly. I haven’t identified any changes I made that could trigger this issue, which is preventing me from using my PC for gaming. It seems to happen randomly—either during normal use or when closing an app.
I’ve uninstalled some applications reported with the same problem (iCue), but that didn’t resolve anything. I do have a dump file, though I’m not sure what to do with it. I’m unsure about the Svchost.exe issue mentioned in the file and would really appreciate any guidance!
Pc specs:
z590 aorus elite ax
3070ti
10700k 3.8ghz
750w corsair txm gold

Here are the dump files:

No, there are no OS updates that match the timing of this issue.
Hi,
The latest change was on August 15th. I visited the Windows update section in settings and ran the ‘fix problems using windows update’. I’m not sure if it worked, but I briefly stress-tested and played some demanding games without any crashes so far. Still, I’m not very sure because I only spent about 15 minutes testing it.
I would install microsoft autoruns64 and turn off cmusbdac.sys, then restart the system.
If you have time before a crash occurs:
unplug any USB audio devices first.
Note that removing USB hardware from the system hides the driver instead of deleting it, which can lead to issues.
Open the Windows Control Panel and Device Manager, locate the option to display hidden devices, enable it, and remove the greyed-out entries.
It seems you have about 7 to 10 minutes before most bugchecks finish.
You might also disable the service if you identify the responsible one, then restart to prevent the crash.
Applying the latest BIOS update is recommended for security patches.

Search for an update for cmusbdac.sys (USB audio driver) or remove it if you no longer need the device.
This tool should eliminate it if you no longer have the hardware.

Some service hosts are triggering the bugcheck.
svchost.exe is likely involved; updating Razer drivers would be a reasonable assumption, though this is just a guess. Also, ensure your mouse firmware matches the drivers—Razor drivers often cause delays before a crash.
Apologies for the generic description; it’s hard to pinpoint exactly which service is causing it.
I suggest updating your Razer driver/software and firmware first.
Then visit your motherboard vendor site and update the Realtek sound driver (this isn’t usually the issue).
cmusbdac.sys is quite outdated and intended for USB audio support (C media, possibly Snowball mic).

Your dumps consistently show 0xEF bugchecks marked as CRITICAL_PROCESS_DIED, indicating a critical failure in a vital Windows process. The affected process is svchost.exe, which manages features that operate as dynamic load libraries (DLLs). This issue might stem from a problem with the svchost DLL itself or could point to a hardware malfunction. 0xEF bugchecks are typically hardware-related.

Hi,
Thanks for the extensive reply!
I carried out a repair on the Windows install, and the CMUSBDAC.sys was put into the windows.old folder automatically, I can’t find it anywhere on Autorun, would that mean it’s not actually on my current install of windows? I do have a snowball mic so that was a good call. Is there something I should download in its place?
I uninstalled and reinstalled all the razer software, and removed some I don’t use. All drivers have been updated - besides the CMUSBDAC above - however some of the razer drivers dont seem to have updated and are still the old ones? The only razer peripheral I have is the original black widow chroma, which doesn’t have any drivers on their website as far as I can tell.
I am waiting for a USB to arrive so I can update the bios, but haven’t had a crash since doing all of the above.
I will keep this thread updated on if it’s actually fixed.
Thank you!
Hi,
I saw svchost.exe in the dump file, and after a repair on Windows it seemed to work better. I’m planning a full stress test today. The previous one last night didn’t fail again, so maybe it was just software problems. When you mention hardware, do you think any specific part might be faulty? I’m assuming it could be an SSD or power supply unit.
I haven’t overclocked my RAM myself since it was built from a company and has been stable since 2021. It’s possible random issues are happening. I’ve tried a few things (refer to my reply to @johnbl) and will test the XMP profile next.
Thanks! Honestly, this came out of nowhere—my computer ran perfectly until yesterday. If it’s hardware-related, it might just be an excuse for upgrading.
Whilst the CRITICAL_PROCESS_DIED bugcheck is most usually has a hardware cause it can also be triggered by software sometimes.
Your RAM is overclocked, it's clocked at 3200MHz which is the design speed of that RAM, but that's an overclock. This is from the dumps...
Code:
Part Number CM4X8GD3200C16K4
Attributes 1
Extended Size 0
Configured Memory Speed 3200
The
native (SPD) speed of that RAM
is 2133MHz. I suggest you remove the XMP overclock completely and run the RAM at its native speed to see whether the system is stable then.
And yes, things can and do fail after some time. Four years isn't a long time in the life of PC components but entropy always increases, so components can become flaky after a time, RAM especially. Additionally, since the RAM you have (Corsair CM4X8GD3200C16K4) is not on the
Qualified Vendor List for your Gigabyte Z590 AORUS ELITE AX
motherboard it's even more likely that as the RAM has aged it's become flaky.
