Random BSOD Bad Pool Header

For the last few weeks I've been getting random BSOD with Bad Pool Header.

I have attached the diagnostics and hope someone will be able to help

Do you get BSOD's often?

Reduce items at start-up:Perform a clean boot: Run the System File Checker that scans the of all protected Windows 7 system files and replaces incorrect corrupted, changed/modified, or damaged versions with the correct versions if possible:

No it only happens here and there. Maybe once a month if that but in the last few week I got it twice. I have not done anything so far and now it has been fine again for a week.

I ran the System File Checker and it says it did not find any integrity violations

Ok now it is really bad. Yesterday once and today got the BSOF 3 times already. Now only running minimum programs at start up and clean boot did not help either. As per post above I did a System File Checker the other day and that did not fix anything either.

I have attached the diagnostics again from today to see if something obvious is causing it.

Something tells me you didn't really number down the items at start up.

To perform a clean install of a driver, follow this tutorial:Use Revo Uninstaller to uninstall stubborn software. Opt for Advance Mode while uninstalling which allows you to remove leftover registry:-Take memtest. Run for 8 passes and test each stick in a know good slot for an additional 6 passes.
Quote:
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.
information   Information
Errors are sometimes found after 8 passes.

Do this test overnight, before going to bed.
