Hi, I have a dell optiplex 7010 with 64bit windows and whenever I restart I am now getting blue screen with this error.
Here is the link to minidump on skydrive.
I have updated all the drivers and bios from dell website. Please advise if there is anything which needs fixing.
Thank you

Hello abaloch05.

It is a stop 0x76, basically it is caused by some driver malfunctioning.

But the failing driver is not traced in the solitary crash dump that you uploaded.

Enable Driver Verifier to monitor the drivers.
Driver Verifier - Enable and Disable
Run Driver Verifier for 24 hours or the occurrence of the next crash, whichever is earlier.

information   Information
Why Driver Verifier:
It puts a stress on the drivers, ans so it makes the unstable drivers crash. Hopefully the driver that crashes is recorded in the memory dump.

How Can we know that DV is enabled:
It will make the system bit of slow, laggy.

warning   Warning
Before enabling DV, make it sure that you have earlier System restore points made in your computer. You can check it easily by using CCleaner looking at Tools > System Restore.

If there is no points, make a System Restore Point manually before enabling DV.

Tip   Tip

Let us know the results, with the subsequent crash dumps, if any. Post it following the Blue Screen of Death (BSOD) Posting Instructions.

Caused by a driver not cleaning up correctly after an I/O.
Arg1: 0000000000000000, Locked memory pages found in process being terminated.
Arg2: fffffa8010f2a060, Process address.
Arg3: 0000000000000002, Number of locked pages.
Arg4: 0000000000000000, Pointer to driver stacks (if enabled) or 0 if not.
    Issue a !search over all of physical memory for the current process pointer.
    This will yield at least one MDL which points to it.  Then do another !search
    for each MDL found, this will yield the IRP(s) that point to it, revealing
    which driver is leaking the pages.
    Otherwise, set HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Memory
    Management\TrackLockedPages to a DWORD 1 value and reboot.  Then the system
    will save stack traces so the guilty driver can be easily identified.
    When you enable this flag, if the driver commits the error again you will
    see a different bugcheck - DRIVER_LEFT_LOCKED_PAGES_IN_PROCESS (0xCB) -
    which can identify the offending driver(s).

Hi, if it BSODs before windows load, boot into safe mode and disable Driver Verifier.
Then boot normally again, and enable Driver Verifier again. Just make it sure that you are not selecting any driver provided by "microsoft" and "unknown".

So have another try?
