After powering off my computer for a minute to plug in a new keyboard, I turned the system on and suddenly the sound driver and a system device called "Plug and Play Software Device Enumerator" were failing.

(image removed)

How do I repair that system driver? I tried reinstalling drivers and 2 other sound cards, all had the same issue. The corrupted Device Enumerator apparently inhibits the sound device from working. The error I kept getting when reinstalling sound drivers was "The I/O operation has been aborted because of either a thread exit or an application request" (image removed)

For the moment, I'm at a loss. I don't know what to do. I'm scared and afraid :cry:

I also tried removing rebooting and reinstalling that system driver. Turns out when you remove it, it's gone. I had to google a way to reinstall it by tweaking an INF file. Anyway it solved nothing because it still comes up corrupted. Is there some binary file that driver depends on that might have been corrupted, that I can replace?

Otherwise I'm still at a loss as of what to do ;\

Thanks warwagon, but that does not appear to be the issue.

After Googling awhile, I've found people with similar problems. I also found a somewhat helpful thread on another site that explains how to reinstall the Plug and Play Software Device Enumerator, as well as various people complaining about the driver failing.

But in the end, none of the related files on my system were corrupted (I compared checksums with files on other systems) and reinstalling the driver always resulted in a failure message "The driver may be corrupted or missing. (Code 39)".

I guess I'll be reformatting. :no:

Hello to everyone

I realize that I am about 9 months late with this post (just joined) but I am having the exact same problem as Isuldor.

The Plug and Play Software Device Enumerator reports the error "The driver may be corrupted or missing. (Code 39)" in the Device Manager.

So far I have uninstalled the drivers for the sound card, uninstalled the PnP Enumerator and reinstalled it after editing "allmachine" Setup File in Notepad by deleting line 22 under "Control Flags" After a reboot, the same error occurs. I have also replaced the swenum.sys and streamci.dll files from a known working box and repeated the above process all over again.

I also searched the registry for SWENUM and found a folder by that name. It contained a corrupt key. I was unable to manually delete the key but I ran Registry Mechanic after uninstalling the PnP Enumerator and then reinstalled it. Now the folder called SWENUM is gone and my situation is exactly the same.

I cannot figure out if the problem is hardware or sofware related!

I REALLY don't want to reformat. If anyone can help I would be greatly appreciative.

My Specs:

Intel D865PERL Motherboard

Windows XP SP 2

P4 2.6 Ghz Processor

1 GB of RAM

NVidia 5200 AGP Video Card

On Board Sound running the SoundMax drivers for my audio

Thanks!

Hello jacomus, welcome to the forums.

Looking back now, I wasn't ever able to solve the problem. It did appear to be a software problem, since I tried multiple hardware configurations. And the error message was certainly no help, since I also verified (using a hash sum calculator) that all of the files in question were in fact not corrupt. It's unfortunate that the problem has not been experienced and dissected by smarter Neowin users. I bid you luck on a fresh operating system installation in your near future. :cry:

I've just had a similar problem, but managed to fix it. I installed some drivers (Conexant 878 tv tuner drivers) that caused my system to reboot halfway through the install and corrupt all sorts of drivers at the same time. Scandisk gave me at least three pages of errors. The Plug and Play Software Device Enumerator was showing a code 39, all my cd drives were inaccessible, and pretty much everything related to multimedia was broken.

What worked for me was to boot into safe mode, insert the WinXP SP2 CD, and copy the I386 folder to the hard drive. Then I used regedit to set the following registry key : HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/CurrentVersion/Setup/SourcePath to point at the folder containing the I386 folder (eg. "C:\").

Once I restarted, the Device Manager was back to normal, and everything seems to be working again.

The only other thing I did was to reinstall my Audigy 2 ZS drivers before loading safe mode. Installation finished on the same reboot as everything began working again.

If all that doesn't work, maybe http://www.updatexp.com/scannow-sfc.html will help.

    • Skype for Business Server SE now available because Teams can't solve one problem

      I commented on ONE thing, the rest is just an explanation for the unintroduced. The distinction between Skype and SfB was not cloud vs on-prem, period. That's all I refuted.
    • This DDR5-6400 CL36 32GB RGB RAM that supports both AMD and Intel is only $72

      "that supports both AMD and Intel" Why even say such a thing? That's like saying an HDMI cable that supports both LG and Dell displays or something.

    • Giga Computing launches liquid- and air‑cooled AI servers built on NVIDIA HGX B200 platform

      By Fiza Ali · Posted

      Giga Computing launches liquid- and air‑cooled AI servers built on NVIDIA HGX B200 platform by Fiza Ali Giga Computing has today expanded its enterprise‑grade GPU server portfolio with four new systems built upon NVIDIA’s HGX B200 platform. These servers combine advanced cooling options with support for Intel’s latest AI‑optimised Xeon 6 processors. According to NVIDIA, HGX B200, powered by the company's Blackwell architecture, delivers up to 15 times faster real‑time inference, where the trained AI model makes predictions or decisions based on new data, on trillion‑parameter models compared to the previous generations. The 4U GIGABYTE G4L3 Series features separate CPU and GPU chambers and employs an advanced direct liquid‑cooling (DLC) system. According to the tech giant, this approach not only sustains peak performance during demanding AI training and inference tasks but it also drives down both power consumption and data‑centre cooling costs. The two variants which are currently available are the G4L3‑SD1‑LAX5, which supports the latest Intel Xeon processors, and the G4L3‑ZD1‑LAX5, which supports AMD EPYC CPUs. On the other hand, the GIGABYTE G894 Series uses optimised airflow and works with a variety of x86 platforms and baseboard GPU setups, including NVIDIA’s HGX B200. It comes in two models: the G894‑AD1‑AAX5, which supports Intel Xeon 6900‑Series processors such as the 6962P, and the G894‑SD1‑AAX5, which supports Intel Xeon 6700‑ and 6500‑Series processors, including the 6776P. GIGAPOD, Giga Computing’s AI supercomputing solution, has also been updated to include the new NVIDIA HGX B200 platforms. Built for the rigours of training large language models and generative AI, it promises improved throughput, higher energy efficiency, and a range of cooling options to accommodate advancing AI demands. With the addition of these HGX B200-powered systems to its lineup, Giga Computing is expanding its server offerings to better support demanding AI workloads. The focus on efficient cooling, compute density, and compatibility with the latest processors positions these new models as options for enterprises scaling up AI infrastructure.
