  1. Hi Guys,

    I'm fed up with Windows 7 and my random BSODs. I've attached my latest minidump, but I have plenty more if you want to see them.

    PC is a home build:
    Asus P5QL Pro
    CPU Intel Core 2 Quad E6600
    8 Gb Compatible memory (I can't remember the exact details)

    Symptoms are Random BSODs with ramdom error codes, please see my minidump for details.

    If anyone can help analyse the cause of the BSODs I will be forever grateful

    Many thanks

    Though the minidump file did not specifically cite any particular cause the fact that you have multiple BSODs with multiple error codes can be a strong indicator of either corrupted memory or wrong memory voltages set in the BIOS.

    Therefore, for diagnostic purposes run Memtest.

    1. Go to and download the latest ISO version which is 4.20. It is free and perfectly safe.

    2. Burn ISO to a CD.

    3. Place CD in your drive and reboot with CD in drive. (You might have to place your drive as first bootable in your BIOS) The test will take over.

    There is a Tutorial: How to use Memtest in our Guides and Tutorials forum; follow the instructions. There is a newer version than what is listed; use the newer. If you need to see what the Memtest screen looks like go to reply #21. The third screen is the Memtest screen.

    Step1 - Let it run for a LONG time. The rule is a minimum of 7 Passes (not hours; this test is not measured by hours); the more Passes after 7 so much the better. The only exception is if you start getting errors before 7 Passes then you can skip to Step 2.

    There are 8 individual tests per Pass. Many people will start this test before going to bed and check it the next day.

    If you have errors you have corrupted memory and it needs to be replaced.

    Step 2 – Because of errors you need to run this test per stick of RAM. Take out one and run the test. Then take that one out and put the other in and run the test. If you start getting errors before 7 Passes you know that stick is corrupted and you don’t need to run the test any further on that stick.

    * Get back to us with the results.

    *** If Memtest shows no errors then find the voltage specs of your RAM and compare it to the voltage setting in your BIOS. Do they match?

    Fixed - I think!

    Thanks for your help, however I went for a different route to fix and it seems to have worked which points at a virus or seriously corrupt system files.

    I replaced my HDD with an new 256Gb SSD and did a clean install of windows and re-installed all my software. I have had no problems since.

    A windows repair or restore just didn't work, and I checked the integrity of the old HDD and it was fine.

    All the best
