Intermittent BSoD: Page Fault in Non Paged Area

Intermittent (every 4-8 weeks) crash blue screen reports PAGE FAULT IN NON PAGED AREA. I assume this is a failed memory access attempt. I have, over the course of time, replaced all RAM and my video card. This PC gets used several hours daily.

The crash has happened both times I tried to drop a flour bomb in MS Flight Simulator X (atypical activity; computer is usually used for web access and development); it's otherwise unpredictable. Seconds after boot with two apps open (less common), and after long memory intensive sessions. This can't be related to software or hardware install; I tried the on(blue)screen suggestions to no effect.

A bunch of system info in the snippet.

Could this be a cache problem on the motherboard?

Thanks.

Could be Heat sometimes.... Try to uncover the Case while you are running "MS Flight Simulator" and pass your finger tips on the VGA card's chip to see if its heated.

If it is you might need anther cooling fan inside the case...

Great way to get a day away from the computer.

Memtest+ showed an error (twice) in test 4 with good and bad addresses. I gather that's suggestive of a failing module (my reference for interpreting results of memtest+: http://www.houseofhelp.com/forums/showthread.php?p=187972) so I'll do a little RAM shuffle later. I have extra DIMMs; hopefully it's not a slot.

Vendor's disk diagnostics all OK.

Chkdsk deleted an index for a file and then rescued that same orphaned file; otherwise OK.

FSX still crashes: BSoD suggests mismatched memory, etc.

Will return after completing RAM switches.

Memtest+ did reveal RAM problems. I tried to change the positions of my existing DIMMs (2x1GB, 2x256MB) but this mb/cpu doesn't like to do that (other cases documented on web) and wouldn't boot for a while. So I got a really big hammer....then went for a walk. I replaced the RAM (2x1GB samsung, 2x512mb infineon) and Memtest+ is happy, but FS still crashes (I realize now it's a different crash - with no specific message - than the PAGE_FAULT_IN_NON_PAGED_AREA). The links are helpful; I'm thinking it's a problem with cache or maybe a bus as the HD passed all tests and I've changed video cards. Short of changing the mobo, I guess I'll live with it. Of course, maybe it won't return.

Thank you all.
