  • Hi,

    The attached DMP file is of the PAGE_FAULT_IN_NONPAGED_AREA (50) bug check.

    This indicates that invalid system memory has been referenced.

    Bug check 0x50 usually occurs after the installation of faulty hardware or in the event of failure of installed hardware (usually related to defective RAM, be it main memory, L2 RAM cache, or video RAM).

    Another common cause is the installation of a faulty system service.

    Antivirus software can also trigger this error, as can a corrupted NTFS volume.

    avast!'s Self Protection driver is referencing invalid memory.

    Your avast! is nearly 4 years old, why is it so old? Is it a legitimate copy?

    ---------------------------

    Regardless, remove and replace avast! with Microsoft Security Essentials for temporary troubleshooting purposes:
