Windows 7: BSOD ntoskrnl.exe-7f1c0 while idling

Windows 7 Home Premium 64 Bit

Alright, let's check for driver conflicts.
  • An underlying driver may be incompatible\conflicting with your system. Run Driver Verifier to find any issues. To run Driver Verifier, do the following:
    a. Backup your system and user files
    b. Create a system restore point
    c. If you do not have a Windows 7 DVD, Create a system repair disc
    d. In Windows 7:
    • Click the Start Menu
    • Type verifier in Search programs and files (do not hit enter)
    • Right click verifier and click Run as administrator
    • Put a tick in Create custom settings (for code developers) and click next
    • Put a tick in Select individual settings from a full list and click next
    • Set up the individual settings as in the image and click next
      Attachment 213761
    • Put a tick in Select driver names from a list
    • Put a tick next to all non-Microsoft drivers.
    • Click Finish.
    • Restart your computer.

    If Windows cannot start in normal mode with driver verifier running, start in safe mode. If it cannot start in safe mode or normal mode, restore the system restore point using System Restore OPTION TWO.

    Thanks to zigzag3143 for contributing to the Verifier steps.
    If you are unable to start Windows with all drivers being verified or if the blue screen crashes fail to create .dmp files, run them in groups of 5 or 10 until you find a group that causes blue screen crashes and stores the blue screen .dmp files.
    The idea with Verifier is to cause the system to crash, so do the things you normally do that cause crashes. After you have a few crashes, upload the crash reports for us to take a look and try to find patterns.

    When you are ready to disable Verifier: Start Menu -> All Programs -> Accessories -> Right click Command Prompt -> Run as administrator -> Type the following command and then Enter:
    verifier /reset
    -> Restart your computer.

If we are unable to find a driver, you may need to replace the SSD with an HDD and see if you still have problems. It may be an incompatible piece of hardware is conflicting with your SSD, as well.

It appears you're disk system is causing the error. Please run a check disk using this tutorial.
Use Option one and follow steps 1-5. Because this is your system disk, jump to number 11 to finish.

Also, be sure all your disk drive connections are tight including the power cable.

The requested page of kernel data could not be read in. Typically caused by
a bad block in the paging file or disk controller error.

If the error status is 0xC000000E, 0xC000009C, 0xC000009D or 0xC0000185,
it means the disk subsystem has experienced a failure.

Arg1: fffff6fc500223e8, lock type that was held (value 1,2,3, or PTE address)
Arg2: ffffffffc000000e, error status (normally i/o status code)
Arg3: 000000007731d880, current process (virtual address for lock type 3, or PTE)
Arg4: fffff8a00447d08e, virtual address that could not be in-paged (or PTE contents if arg1 is a PTE address)

EXCEPTION_CODE: (NTSTATUS) 0xc0000006 - The required data was not placed into memory because of an I/O error.

To determine whether you are running Verifier:
  • Open a command prompt via Start Menu -> All Programs -> Accessories -> Command Prompt

  • Type
    verifier /query

You should get a list of drivers being verified if they were enabled.

You're the second person to say that within the last 24 hours... Not sure what configuration you and the other person are running that causes that. Anyway, the fact that it makes a list means it is enabled. Otherwise, you would get a short message saying no drivers are currently verified.

You're welcome.

The Verifier enabled crashes will be in the same place as before for the .dmp files. Just follow the again and we will analyze them.

Just thought of something else. Is your SSD set to turn off during idle? See Hard Drive - Turn Off Hard Disk After Idle or Never and see if setting it to never turn off helps. You may want to disable Verifier for the time being to test. And no, setting it to never is not bad for the SSD. It actually allows it to do its garbage collection. :)

I do not think there is a way to distinguish between the two. We should cross that bridge when we get to it, though. Let's see if this works, first.
