There are a number of reasons why you could be encountering issues with ahcix86s.sys. Most of the issues concerning sys files involve Blue Screen of Death (BSOD) errors. These types of ahcix86s.sys errors can be cause by hardware problems, outdated firmware, corrupt drivers, or other software-related (eg. EaseUS Disk Copy 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 ahcix86s.sys BSOD errors after you've installed new hardware, software (EaseUS Disk Copy), or performed a failed Windows Update. In other cases, software corruption caused by a malware infection can lead to ahcix86s.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 ahcix86s.sys Blue Screen of Death error after recent changes.

Step 3: Perform a Windows Update.

  4. If updates are available for download, click "Install Updates".
  5. After the update is completed, restart your PC.

If Windows Update failed to resolve the ahcix86s.sys error message, please proceed to next step. Please note that this final step is recommended for advanced PC users only.

If Those Steps Fail: Download and Replace Your ahcix86s.sys File (Caution: Advanced)

If none of the previous three troubleshooting steps have resolved your issue, you can try a more aggressive approach (Note: Not recommended for amateur PC users) by downloading and replacing your appropriate ahcix86s.sys file version. We maintain a comprehensive database of 100% malware-free ahcix86s.sys files for every applicable version of EaseUS Disk Copy. Please follow the steps below to download and properly replace you file:

  1. Locate your Windows operating system version in the list of below "Download ahcix86s.sys Files".

    Windows 10: C:\Program Files (x86)\EaseUS\Todo Backup\BUILDPE\x86\Drivers\RAID\AMD\
  4. Restart your computer.

GEEK TIP : We must emphasize that reinstalling Windows will be a very time-consuming and advanced task to resolve ahcix86s.sys problems.

Download ahcix86s.sys Files (Malware-Tested 100% Clean)

CAUTION : We strongly advise against downloading and copying ahcix86s.sys to your appropriate Windows system directory. EaseUS typically does not release EaseUS Disk Copy SYS files for download because they are bundled together inside of a software installer. The installer's task is to ensure that all correct verifications have been made before installing and placing ahcix86s.sys and all other SYS files for EaseUS Disk Copy. An incorrectly installed SYS file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
