What are mvumis.sys Error Messages?

mvumis.sys Blue Screen of Death (BSOD) Errors

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 These types of mvumis.sys errors can be cause by hardware problems, outdated firmware, corrupt drivers, or other software-related (eg.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

mvumis.sys could not be found.
mvumis.sys failed to load.
The file mvumis.sys is missing or corrupt.
Windows failed to start - mvumis.sys.

A problem has been detected and Windows has been shut down to prevent damage to your computer. The problem seems to be caused by the following file: mvumis.sys.

:( Your PC ran into a problem that it couldn't handle, and now needs to restart. You can search for the error online: [BSOD] (mvumis.sys).

STOP 0x0000001E: KMODE EXCEPTION NOT HANDLED (mvumis.sys) STOP 0×0000007A: KERNEL DATA INPAGE (mvumis.sys) STOP 0x0000000A: IRQL NOT LESS EQUAL (mvumis.sys) STOP 0x0000003B: SYSTEM SERVICE EXCEPTION (mvumis.sys) STOP 0x00000050: PAGE FAULT IN A NONPAGED AREA (mvumis.sys) STOP 0x0000007E: SYSTEM THREAD EXCEPTION NOT HANDLED (mvumis.sys)

It's Critical to Resolve Blue Screen of Death Errors

In the majority of cases, you will encounter mvumis.sys BSOD errors after you've installed new hardware, software (Windows), or performed a failed Windows Update. In other cases, software corruption caused by a malware infection can lead to mvumis.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 mvumis.sys Blue Screen of Death error after recent changes.

How to Fix mvumis.sys Errors in 3 Steps (Time to complete: ~5-15 minutes)

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

Step 1: Restore your PC back to the latest restore point, "snapshot", or backup image before error occurred.

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

Hit the Windows Start button
When you see the search box, type "System Restore" and press "ENTER".
In the search results, find and click System Restore.
Please enter the administrator password (if applicable / prompted).
Follow the steps in the System Restore Wizard to choose a relevant restore point.
Restore your computer to that backup image.

If the Step 1 fails to resolve the mvumis.sys error, please proceed to the Step 2 below.

Step 2: Run SFC (System File Checker) to restore the corrupt or missing mvumis.sys file.

System File Checker is a utility included with every Windows version that allows you scan and restore corrupted system files. Use the SFC tool to fix missing or corrupt mvumis.sys files (Windows XP, Vista, 7, 8, and 10):

Hit the Windows Start button
In the search box, type "cmd" but DO NOT PRESS "ENTER".
Press and hold "CTRL-Shift" on your keyboard while pressing "ENTER".
You'll be prompted with a permission dialog box.
In the box, click "YES".
You should have a black screen with a blinking cursor.
In that black screen, type "sfc /scannow" and hit "ENTER".
SFC will begin scanning for mvumis.sys issues and any other system file problems.
Follow any on-screen commands to complete the process.

Please be aware that this scan might take a while, so please be patient while it is working.

If this Step 2 fails as well, please proceed to the Step 3 below.

sfc /scannow

Step 3: Perform a Windows Update.

When the first two steps haven't solved your issue, it might be a good idea to run Windows Update. Many mvumis.sys error messages that are encountered can be contributed to an outdated Windows Operating System. To run Windows Update, please follow these easy steps:

Hit the Windows Start button
In the search box, type "Update" and press "ENTER".
In the Windows Update dialog box, click "Check for Updates" (or similar button depending on your Windows version)
If updates are available for download, click "Install Updates".
After the update is completed, restart your PC.

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

Show 1 more directory +

Windows 10: C:\Windows\System32\DriverStore\FileRepository\mvumis.inf_x86_bffd5d6c758bdfbe\

Restart your computer.

If this final step has failed and you're still encountering the error, you're only remaining option is to do a clean installation of Windows 10.

GEEK TIP : We must emphasize that reinstalling Windows will be a very time-consuming and advanced task to resolve mvumis.sys problems. To avoid data loss, you must be sure that you have backed-up all of your important documents, pictures, software installers, and other personal data before beginning the process. If you are not currently backing up your data, you need to do so immediately.

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

CAUTION : We strongly advise against downloading and copying mvumis.sys to your appropriate Windows system directory. Microsoft typically does not release Windows 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 mvumis.sys and all other SYS files for Windows. An incorrectly installed SYS file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
