    BSOD "Unexpected Kernel Mode Trap" occurring randomly


    My computer is just a few months old, started getting BSOD's randomly, usually when on desktop or just running Chrome browser.
    System details:
    Windows 7 Pro 64
    Gigabyte Z77-HD3
    Intel i5 3.4MHz
    AMD Radeon 7700HD
    8GB DDR3

    Hi 13islucky.

    Are you overclocking? As you are getting BSODs, you should stop overclocking and run all the hardware components like CPU, GPU and RAM to their default settings. Also set the BIOS to default, too.

    Intel RST is failing here:
    Code:
    Unable to load image \SystemRoot\system32\DRIVERS\iaStor.sys, Win32 error 0n2
    *** WARNING: Unable to verify timestamp for iaStor.sys
    *** ERROR: Module load completed but symbols could not be loaded for iaStor.sys
    Get rid of intel rapid storage. First uninstall it from Control Panel > Programs and Features. Then Uninstall the driver from device manager.

    1. Right click on "my computer" icon and click "manage" on the context menu.
    2. It will open the "computer management" window.
    3. Select "Device Manager" in the left pane, It will list all the existing devices up.
    4. Expand "IDE ATA/ATAPI controllers" by clicking on the triangle in front of it.
    5. Select one Intel device item under it, right click, uninstall.
    6. Continue the process for all Intel items under "IDE ATA/ATAPI controllers"
    7. Now restart the computer. At restart, windows will auto configure the appropriate native system driver.

    Do some Disc checks.

    1. Reseat the sata and power.
    2. Run chkdsk /f/r, following the option two of the tutorial Disk Check
    3. Seatool for dos: SeaTools | Seagate download
      Burn it in a blank cd. boot from the CD, click on "Accept", wait for it to finish detecting the drives, then in the upper left corner select "Basic Tests", then select "Long Test" and let it run.
    4. Post screenshots of both your HDDs using CrystalDiskInfo - Software - Crystal Dew World

    Test your RAM modules for possible errors.
    How to Test and Diagnose RAM Issues with Memtest86+
    Run memtest for at least 8 passes, preferably overnight.

    Finally, at least as a test, uninstall Eset. Use Microsoft Security Essentials as your antivirus with windows inbuilt firewall, and free MBAM as the on demand scanner.
    Download, install and update those, and then run full system scans with both of them, one by one.

    Let us know the results.

    UNEXPECTED_KERNEL_MODE_TRAP (7f)
    This means a trap occurred in kernel mode, and it's a trap of a kind
    that the kernel isn't allowed to have/catch (bound trap) or that
    is always instant death (double fault).  The first number in the
    bugcheck params is the number of the trap (8 = double fault, etc)
    Consult an Intel x86 family manual to learn more about what these
    traps are. Here is a *portion* of those codes:
    If kv shows a taskGate
            use .tss on the part before the colon, then kv.
    Else if kv shows a trapframe
            use .trap on that value
    Else
            .trap on the appropriate frame will show where the trap was taken
            (on x86, this will be the ebp that goes with the procedure KiTrap)
    Endif
    kb will then show the corrected stack.
    Arguments:
    Arg1: 0000000000000008, EXCEPTION_DOUBLE_FAULT
    Arg2: 0000000080050033
    Arg3: 00000000000406f8

    Awesome, thanks for the quick response and all the good ideas. I haven't overclocked anything myself, so it would only be OC'd if they did it when building my system. I started with your first idea of uninstalling the Intel Rapid Storage and see if that does the trick. I'll let you know as I try the steps, which one solves my BSODs. Thanks again!
