How can I figure out what is causing my blue error screen?

by on June 17, 2009

Q: A while back when I was going to turn off my computer it it would restart again about 50% of the time. I did a little research and found out that this was because there was some sort of error with possibly new software or new drivers. I found out that I could change this so that the computer wouldn’t restart and instead a sort of blue screen would appear where I could see what the error was. Of course I have no idea what to make of it and was wondering if you guys had any advice on what I can do to fix this problem.

The blue error screen said

PFN_LIST_CORRUPT

then there was some text about “if this is the first time this happens restart the computer…”

    PFN_LIST_CORRUPT issues are usually cause by one of three different things:

    1) Bad Ram
    2) Bad Harddrive sectors
    3) BIOS issues

    It’s probably going to be one of the first two, so I’d suggest you try doing a diagnostic of your RAM first. Grab the free download of MemTest86 ( http://www.memtest86.com/ ) and follow their instructions to create a bootable disk/cd/usb stick, and use their software to run a test of your RAM.

    Let us know how it goes.

      I did as you asked and it seems that ram isn’t the problem after the test its said pass complete, no errors ill leave you with the other info as well in case you might need it.

      Mem map:e820
      Rsvs_Mem: 12k
      Cached: 2047m
      Iter: 3
      Act_Cpus:1
      Teest_Sel:Std
      Cpu_Sel:Single
      Ecc_Mem:off
      Pass:1
      Errors:0
      Ecc err:0
      Pass Complete, No Errors.

    You’re going to need to do more than one pass with Memtest86, since it does different kinds of tests on the memory. I’m going to suggest you let it run for at least 4 hours or 7 passes, which ever is faster.

      Ok i did it again…

      Time: 6:04:43
      Mem map:e820
      Rsvs_Mem: 12k
      Cached: 2047m
      Iter: 30
      Act_Cpus:1
      Teest_Sel:Std
      Cpu_Sel:Single
      Ecc_Mem:off
      Pass:7
      Errors:0
      Ecc err:0
      Pass Complete, No Errors.

    Okay, with that out the way we can take a look at the other possibilities. Next thing to do is to check your harddrive for errors. Right click the drive in Windows Explorer, choose properties. On the tools tab, you will find error checking.

    After this runs, reboot and see if you still have the problem. If you do, check to make sure you’re running the latest non-beta drivers for all of your hardware components.

    If you’re still having trouble, I’ll need the following information:
    Are you running Vista or XP? Also, can you give me a list of all the hardware in your PC.

    Hi ill do as you said funny thing though i have stopped getting the blue screen for a bout a week or so i think its stopped pretty soon after i downloaded a program called RegCure which is supposed to make your computer a bit faster by deleting old registry’s ( i think) do you think that could have anything to do with me not getting a “blue screen” anymore

    Certainly possible. Though there seems to be some people that aren’t too happy with regcure: http://www.maximumpc.com/article/watchdog/is_regcure_legit

    Anyway, glad to hear your issue is cleared up.
