Hi,

We have various different bugchecks attached:

CACHE_MANAGER (34)

A problem occurred within a read or write to a FAT16 or FAT32 file system drive. There may be a physical problem with the disk, or an Interrupt Request Packet (IRP) may be corrupted. Other common causes include heavy hard drive fragmentation, heavy file I/O, problems with some types of drive-mirroring software, or some antivirus software. I suggest running ChkDsk or ScanDisk as a first step; then disable all file system filters such as virus scanners, firewall software, or backup utilities. Check the file properties of FASTFAT.SYS to ensure it matches the current OS or SP version. Update all disk, tape backup, CD-ROM, or removable device drivers to the most current versions.

SYSTEM_SERVICE_EXCEPTION (3b)

An exception happened while executing a routine that transitions from non-privileged code to privileged code.

memory_corruption mentioned throughout the dump, possible hardware related issues given we have not seen any device driver clues yet.

KMODE_EXCEPTION_NOT_HANDLED (1e)

This error typically indicates low disk space, a bug in a device driver or the system BIOS.

BAD_POOL_HEADER (19)

This indicates that a pool header is corrupt.

If we run a !poolval on the 2nd parameter of the bugcheck to check for pool corruption, we get the following:

2: kd> !poolval fffff8a007b12000
Pool page fffff8a007b12000 region is Unknown

Validating Pool headers for pool page: fffff8a007b12000

Pool page [ fffff8a007b12000 ] is __inVALID.

There is pool corruption, this further implies the issue is hardware and not device driver related.

Before we make that call though, please make the following troubleshooting steps:

1. Update to Service Pack 1 ASAP - http://windows.microsoft.com/en-us/windows7/install-windows-7-service-pack-1

2. Remove and replace avast! with Microsoft Security Essentials:

avast! removal tool - http://www.avast.com/uninstall-utility

MSE - http://windows.microsoft.com/en-us/windows/security-essentials-download

If the above software steps do not help, please start by running a Memtest for no less than ~8 passes (several hours):

Memtest86+:

Download Memtest86+ here:

Which should I download?

You can either download the pre-compiled ISO that you would burn to a CD and then boot from the CD, or you can download the auto-installer for the USB key. What this will do is format your USB drive, make it a bootable device, and then install the necessary files. Both do the same job, it's just up to you which you choose, or which you have available (whether it's CD or USB).

How Memtest works:

Memtest86 writes a series of test patterns to most memory addresses, reads back the data written, and compares it for errors.

The default pass does 9 different tests, varying in access patterns and test data. A tenth test, bit fade, is selectable from the menu. It writes all memory with zeroes, then sleeps for 90 minutes before checking to see if bits have changed (perhaps because of refresh problems). This is repeated with all ones for a total time of 3 hours per pass.

Many chipsets can report RAM speeds and timings via SPD (Serial Presence Detect) or EPP (Enhanced Performance Profiles), and some even support changing the expected memory speed. If the expected memory speed is overclocked, Memtest86 can test that memory performance is error-free with these faster settings.

Some hardware is able to report the "PAT status" (PAT: enabled or PAT: disabled). This is a reference to Intel Performance acceleration technology; there may be BIOS settings which affect this aspect of memory timing.

This information, if available to the program, can be displayed via a menu option.

Any other questions, they can most likely be answered by reading this great guide here:
