BSOD on Windows 7 laptop multiple times through the day

[rijocg78]

Hi there,

I am running Windows 7 64-bit on my laptop and it has been crashing continuously over the last couple of weeks with the BSOD, very randomly.

Other than installing the regular Windows updates, I have neither installed any new software nor hardware so I'm not sure what is causing this issue.

It happened again today morning and I have attached the files after running the diagnostic tool.

Could you please review and advise?

regards,
George

MSE is recommended from a strict BSOD perspective, compatibility & stability compared to other antiviruses/internet security software:-

1. Microsoft Security Essentials - Free Antivirus for Windows
2. Malwarebytes - Free

:warn: Do not start the free trial of Malware Bytes; remember to deselect that option when prompted.

Run a full scan with both (separately) once downloaded, installed and updated.

*Post back if this brings more stability or not.​

Then take memtest in the following manner:

Take memtest. Run for 8 passes and test each stick in a know good slot for an additional 6 passes.

• http://www.sevenforums.com/tutorials/105647-ram-test-memtest86.html

The goal is to test all the RAM sticks and all the motherboard slots.

Check your motherboard manual to ensure the RAM sticks are in the recommended motherboard slots. Some motherboards have very specific slots required for the number of RAM sticks installed.

If you get errors, stop the test and continue with the next step.

1. Remove all but one stick of RAM from your computer (this will be RAM stick #1), and run Memtest86 again, for 7 passes.

*Be sure to note the RAM stick, use a piece of tape with a number, and note the motherboard slot.
​

If this stick passes the test then go to step #3.

2. If RAM stick #1 has errors, repeat the test with RAM stick #2 in the same motherboard slot.

*If RAM stick #2 passes, this indicates that RAM stick #1 may be bad. If you want to be absolutely sure, re-test RAM stick #1 in another known good slot.
​

*If RAM stick #2 has errors, this indicates another possible bad RAM stick, a possible motherboard slot failure or inadequate settings.
​

3. Test the next stick of RAM (stick #2) in the next motherboard slot.

*If this RAM stick has errors repeat step #2 using a known good stick if possible, or another stick.
​

*If this RAM stick has no errors and both sticks failed in slot#1, test RAM stick #1 in this slot.
​

4. If you find a stick that passes the test, test it in all the other motherboard slots.

If Part 2 testing shows errors, and all tests in Part 3 show errors, you will need to test the RAM sticks in another computer and/or test other RAM in your computer to identify the problem.

In this way, you can identify whether it is a bad stick of RAM, a bad motherboard, or incompatibility between the sticks.

:info: Errors are sometimes found after 8 passes.
:tip: Do this test overnight, before going to bed.

Post back results.
