What are mpspfltr.sys Error Messages?


mpspfltr.sys Blue Screen of Death (BSOD) Errors

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 These types of mpspfltr.sys errors can be cause by hardware problems, outdated firmware, corrupt drivers, or other software-related (eg.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

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: mpspfltr.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] (mpspfltr.sys).

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

It's Critical to Resolve Blue Screen of Death Errors

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