BSOD on startup - ntoskrnl.exe+6f400

[Ch0nG]

I've had three BSODs that all say they are caused by this address. They always occur on boot.

The bug check strings have been (most recent first):
MEMORY_MANAGEMENT
IRQL_NOT_LESS_OR_EQUAL
PAGE_FAULT_IN_NONPAGED_AREA

Please run MemTest86+ to identify any memory errors, if it does not detect any problems please try a clean boot and report back how it goes

Diagnostic Test

 RAM TEST

Run MemTest86+ to analyse your RAM. MemTest86+ - Test RAM - Windows 7 Forums

   Note

MemTest86+ needs to be run for at least 8 complete passes for conclusive results. Set it running before you go to bed and leave it overnight. We're looking for zero errors here. Even a single error will indicate RAM failure.

Make a photo of the result and post it.

Addition:
If errors show up you can stop the test, remove all sticks but 1 and test this single stick in each slot for 8 passes or until errors show, switch sticks and repeat.
If errors show up and you see them a lot later, no problem, the errors don't affect the test.

Diagnostics Test

 Clean boot

Please try the following:

• Search msconfig and open it
  • Go to the tab services
  • Check 'hide microsoft services'
  • Uncheck all other services
  • Go to the tab startup
  • Disable everything
• Click apply and click ok
• Reboot if asked

See if the problem persist, if the problem does not persist enable in the startup tab in taskmanager 1 item and in the services tab in msconfig also 1 service, reboot and see if the problem persist. Keep doing this until you find the culprit or there is nothing left.
If the problem still persist, try booting in safe mode and see if the problem still persist

Thanks for the reply.

I ran memtest86+ for 12 passes (almost 24 hours) and it found nothing:

I'll run through the clean boot and see what happens. I'm going to reboot a few times for each item as the problem was intermittent. I'll edit my reply when I'm done (or if I find the culprit!).
