  1. Hello, first off thanks in advance for any help i can get. Here goes...

    I keep getting BSODs on my rig composed of:
    Mobo : Asus P5NSLI socket775
    PSU: Ultra Xfinity 500w
    CPU Fan: Masscool 8W553
    CPU: Intel Core2Duo e6400 2.13Ghz
    GFX: XFX GeForce 8500GT 256MbPCIe
    RAM: OCZ Platinum Revision2 2048 (2 sticks) PC6400 DDR2

    I have since replaced a faulty PSU with a Corsair but problems persist with the computer posting and loading the OS and then 5 minutes later, memory dumps. This is a report from Vista on the BSOD:

    Problem signature:
    Problem Event Name: BlueScreen
    OS Version: 6.0.6001.2.1.0.768.3
    Locale ID: 1033

    Additional information about the problem:
    BCCode: 1000007e
    BCP1: C0000005
    BCP2: 824916E3
    BCP3: 89363BDC
    BCP4: 893638D8
    OS Version: 6_0_6001
    Service Pack: 1_0
    Product: 768_1

    Files that help describe the problem:
    C:\Windows\Minidump\Mini010107-03.dmp
    C:\Users\KanChenZ\AppData\Local\Temp\WER-58047-0.sysdata.xml
    C:\Users\KanChenZ\AppData\Local\Temp\WER6EC9.tmp.version.txt


    And finallly, I did manage to get all the memory dumps off but I don't know how to share them on here. If you need them, please advise further action. Previously i thought this was a hardware issue, but now it feels like a corrupt system file or maybe a faulty driver file of some sort. Appreciate the help!!! The following is the code of usual BSOD but every now and then i get IRQL_NOT_LESS... and PAGE FAULT errors....

    *** STOP: 0x0000007E (0xC0000005, 0x824886E3, 0x8935FBDC, 0x8935F8D8)

    luafv.sys: File Virtualization Filter Driver

    I posted some possibly relevant info here about it: http://www.techspot.com/vb/topic106768.html

    Hmmm....

    Okay so how do I go about disabling this driver? I'm not too familiar with the procedures on the other post. Sorry for being a bit naive.

    1. Open the Registry Editor.
    2. Navigate to “HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\luafv”
    3. Double click the “start” string value, and set it to 4.
    4. Reboot and see the improvement.

    Actually it's recommended to backup the registry before editing anything
    You can right click on services key in there (yellow folder) and select "export" and give it a name BackupServicesKey

    But I just went searching about and someone said they fixed it by disabling UAC

    1. Open Administrative Tools in Control Panel
    2. Double-click on System Configuration
    3. Click Continue to accept the UAC prompt
    4. Select the Tools tab
    5. Scroll down and select Disable UAC
    6. Click Launch
    7. Reboot your machine

    Wow.... seems to have done it, disabling the UAC. I don't know what to say other than thanks a million!!!

    This does leave me curious however, what is this UAC and why did it cause these BSODs? Any ideas. I'll keep you posted if it crashes again but as of now... we are over 5 minutes and counting.

    Oh the search thread also stated to turn it back on (although I wouldn't)
    The UAC feature is to protect yourself from yourself (ie that silly big screen that pops up every few seconds (are you sure....? ... Yes just do it :D )

    Anyway, its been about 15mins now :)

    I jinxed it..... :(

    Seems like we got a another BSOD, im updating the BIOS, ASUS says its unecessary but i'll go ahead. Same with XFX Geforce 8500GT display drivers. Don't think it'll change anything but it can't hurt. Will post further BSOD data as it happens. Can't say how much I'm in debt to you. Thank you so much for your help.

    Also to start clean
    Run CCleaner
    And Start->Run-> c:\windows\minidump
    And remove everything presently in there too ;)

    Running 2 hours now and cleaned with Ccleaner. I have copy/pasted both the vista report and the associated minidump. As of now there havent been any issues so hopefully this means nothing but let me know otherwise.

    I got really tired of the issues and then somehow contracted a Google search engine redirect virus. That was the last straw so I reformatted and now I'm back to a clean slate. Thing is, something about my setup is still causing 0xA errors, the PAGE FAULT IN NON PAGED AREA thing. I made sure my memory has the right settings with the mobo, reloaded the new drivers for the video card and right now just waiting for the issue to pop up again...

    Hey guys, sorry about the long wait. Anyways, I decided to do a RAM swap since I finally got my hands on a set. The computer had started to make a long beep before POST or make consecutive beeps. Sure enough the RAM was bad. So far so good, no blue screens at all. However, there is still a small issue. Often times when we go to boot up the computer, it won't POST. No beeps no nothing. A soft reboot gets the ball rolling. Any idea what the issue is?
