Windows 7 Service Pack 1 Freezes Randomly Fix
Since the release of Service Pack 1, Windows 7 users who installed SP1 have been complaining about their computer stability. Windows randomly freezes and crashes without any errors. This problem had been confirmed by Microsoft to exist and now they have finally found a solution to it.
This issue occurs when the computer is utilizing high memory and the memory manager performs frequent paging in and paging out requests. If you want to see the paging requests, you can configure a performance counter for monitoring memory –> page faults/sec.
The issue seems to be with Microsoft Filesystem Filter Manager(Fltmgr.sys). The issue occurs because of a deadlock situation in the Microsoft Filesystem Filter Manager.
