Random Blue Screens about 4~6 hours


I installed recently my brand new Crucial M4 128GB.
Also a fresh version of the Windows 7 Ultimate x64.

But sometimes, about 4 and 6 hours I got random blue screen and reboot almost instantly.

When I get back to the desktop I see the following mensage:

Problem signature:
Problem Event Name: BlueScreen
OS Version: 6.1.7601.
Locale ID: 1046

Additional information about the problem:
BCCode: 4e
BCP1: 0000000000000099
BCP2: 000000000041B8CE
BCP3: 0000000000000006
BCP4: 0000800000000001
OS Version: 6_1_7601
Service Pack: 1_0
Product: 256_1

Files that help describe the problem:

I've done memory diagnostic but it has found no error.
Temps are ok, hottest core with 50C when load.
VGA hardly ever goes over 70C

That blue screen NEVER happened while I was playing a game, it happens when I am doing "nothing".

I' installed that system yesterday, this blue screens begun today.

How would I fix it?

Thank you

  1. Noone?

    Bug Check 0x4E: PFN_LIST_CORRUPT

    This indicates that the page frame number (PFN) list is corrupted.

    For a BCP1 of 0x99:

    A page table entry (PTE) or PFN is corrupted.

    Suspected bad RAM. Run memtest86 and check to see if you get any errors.
  3. Can I use Prime95 instead of memtest86?

    I ran Windows Memory Diagnostic and there were no errors.
  4. You can use Prime 95's blend test.

    I don't have a very high opinion of windows memory diagnostic, and still recommend using memtest at some point. Then again, I've seen plenty of RAM failures that neither test catches [generally an occasionally stuck bit...]
  5. the bluescreen said it dump the errors to a file. Download bluescreenviewer and look at the logs. It should show which file/driver is causing the issue. Good luck
  6. I had not any blue screens/reboots today yet.

    it's stable for about 8 hours, I am not sure how but...

    The only thing I did, yesterday, was pressing F8 while the startup and select: "Start with the last valid configuration" or something like that.

    I also ran today the "windows error-cheking".

    I ran today the Prime95 and I left it about 25 minutes, had no problem.
  7. Well, today I had again a blue screen (When I was away, doing nothing).

    It got stable for more than 16 hours.

    So I decided to follow this guy's problem:


    I did what he said, I also OC a bit my proc.

    I ran Prime95 for 30 minutes using 15.1 GB of my RAM (94%)

    I had no problems.

    There are two print Screens:
