While using a Windows 10 computer, some users may encounter a Blue Screen of Death (BSOD) related to the dxgmms2.sys file. This type of error typically causes the system to restart unexpectedly, disrupting normal usage.
This article will explain the common causes of the dxgmms2.sys BSOD and provide multiple effective solutions to help restore system stability.
What Is dxgmms2.sys?
dxgmms2.sys is a critical system file in Windows responsible for managing the DirectX Graphics MMS (Memory Manager Subsystem) in kernel mode. It is closely tied to DirectX rendering and your graphics card driver. If this file becomes corrupted or fails, the system may crash due to issues processing graphics-related tasks.
Common Causes of dxgmms2.sys Blue Screen Errors
Outdated or Corrupted Graphics Drivers:
The most common cause. Incompatible or broken drivers prevent proper calls to dxgmms2.sys.
Damaged Windows System Files:
Corrupted or missing system files may trigger this error indirectly.
Hardware Issues:
Problems with the graphics card or RAM may also lead to BSODs.
Software Conflicts or Malware:
Conflicting programs or malicious software can corrupt system files, causing crashes.
Failed or Incomplete Windows Updates:
Partial updates may cause driver incompatibility with the OS.
