What are ALCXNT.SYS Error Messages?


ALCXNT.SYS Blue Screen of Death (BSOD) Errors

There are a number of reasons why you could be encountering issues with ALCXNT.SYS. Most of the issues concerning sys files involve Blue Screen of Death (BSOD) errors. These types of ALCXNT.SYS errors can be cause by hardware problems, outdated firmware, corrupt drivers, or other software-related (eg. Audio:Realtek ALC655 AC'97 AUDIO update) issues. Some of these errors include:

It's Critical to Resolve Blue Screen of Death Errors

In the majority of cases, you will encounter ALCXNT.SYS BSOD errors after you've installed new hardware, software (Audio:Realtek ALC655 AC'97 AUDIO), or performed a failed Windows Update. In other cases, software corruption caused by a malware infection can lead to ALCXNT.SYS Blue Screen of Death errors. Therefore, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.


GEEK TIP : As a rule of thumb, it's always a good idea to create a Windows "Snapshot" backup / System Restore Point before making any hardware or software changes to your computer. That way, it's very easy to restore your system in the unfortunate event you encounter a ALCXNT.SYS Blue Screen of Death error after recent changes.

If you're encountering one of the error messages above, follow these troubleshooting steps to resolve your ALCXNT.SYS issue. These troubleshooting steps are listed in the recommended order of execution.

To begin System Restore (Windows XP, Vista, 7, 8, and 10):

  1. Hit the Windows Start button
  2. When you see the search box, type "System Restore" and press "ENTER".
