Blue Screen Errors-- stop 0x1A
Hi everyone,

My friend just recently upgraded me to Windows 7 64 bit and I've been getting a lot of blue screen errors. I've tried to make sure all my drivers are updated, but I've had no luck at all.
It is a pretty new computer that I built with all new parts the dmp files are at the bottom of this page

I seem to get two different errors the most. One is called Memory_Management (1A) 

Problem signature:
  Problem Event Name: BlueScreen
  OS Version: 6.1.7601.2.1.0.256.1
  Locale ID: 1033

Additional information about the problem:
  BCCode: 1a
  BCP1: 0000000000005003
  BCP2: FFFFF70001080000
  BCP3: 00000000000008BA
  BCP4: 000008BC00001170
  OS Version: 6_1_7601
  Service Pack: 1_0
  Product: 256_1


here are my latest dmp files and help would be great

Hi,

Two dumps attached:

MEMORY_MANAGEMENT (1a)

A severe memory management error occurred.


BugCheck 1A, {5003, fffff70001080000, 8ba, 8bc00001170}


If we take a look at the first parameter of the bugcheck, we can see it's 5003 which means 'An unknown memory management error occurred.'


SYSTEM_SERVICE_EXCEPTION (3b)


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


This bugcheck is generally related to a video driver issue.


Ensure you have the latest video card drivers. If you are already on the latest video card drivers, uninstall and install a version or a few versions behind the latest to ensure it's not a latest driver only issue. If you've already tried the latest version as well as many possible previous versions, you can try a beta driver if available.


In your loaded drivers list, sptd.sys is listed. sptd.sys = SCSI Pass Through Direct Host - Daemon Tools (known BSOD issues with Win7).


Remove this driver with the sptd uninstaller: http://www.duplexsecure.com/en/downloads


If the following does not help, run a Memtest. Possible memory issues given the bugchecks we have here:


Memtest86+:

Download Memtest86+ here:

http://www.memtest.org/

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:
