unexpected shut down and random freezing RRS feed

  • Question

  • Here is my dump file- https://skydrive.live.com/#cid=EE011F2548FEF39D&id=EE011F2548FEF39D%21104

    Windows 7 ultimate 32-bit

    Dell Inc

    Latitude E6400

    Bios Phoenix ROM PLUS Version 1.10 A32

    Intel(R) Core 2Duo CPU 2.26GHz

    2048 RAM



    My computer haas steadily become slower and unresponsive. I bought this computer used with vista installed. After I installed a new OS, everything worked fine. I installed and updated some drivers, cleaned things up, but this lag still persists. Is this some kind of driver problem?

  • Hi,

    Dump file indicates this BSOD is related to iastor.sys. Bug Check: C5.

    iastor.sys is the Intel Matrix Storage Manager driver. Look for BIOS and chipset updates (and other on-board drivers).

    Intel Downloads


    Intel Matrix Storage Manager - be sure to check for DATE and set for version of Windows and chipset

    Regarding the error code 0xC5 was received, you can refer to Bug Check 0xC5: DRIVER_CORRUPTED_EXPOOL (Windows Debuggers).

    Hope it helps.
