BSOD - KERNEL_DATA_INPAGE_ERROR (7a)

Question

My laptop suffered this today when moving files from a disk partition (C:) to another (D:). Did a hard boot when failed to restart for 2 1/2 hours after BSOD, and seemingly working okay albeit with some lags.

Worried if it happened again so I attempted to analyze via WinDbg through the guides from Microsoft and various websites, and getting confused on which cause I need to focus.

I attached DMP file here. From my understanding it pinpoints towards LiveUpdate.exe and ntkrnlmp.exe, but unsure about it. Please advise about this error and the steps I need to take after this - is System Restore applicable on this case?

Answer 1

Ntkrnlmp.exe is short for Windows New Technology (NT) operating system kernel. It is a fundamental component of the Windows OS and is in charge of several high-value tasks and processes.

When you get a blue-screen error with ntkrnlmp.exe as the faulty process, this usually means something else caused the issue which directly affected the kernel. In our situation, it was the faulty update service: LiveUpdate.exe.

Yes, running chkdsk would be a good idea. Along with that command line, we also suggest running SFC and DISM since they both aim to repair system issues.

Answer 2

Thank you for the reply. How about the ntkrnlmp.exe? Does it related to the problem as well?

Indeed my computer is running okay now without the same BSOD, although I feel accessing files in My Computer become slightly slower to load after the event. Any recommendation on that - would running CHKDSK is feasible?

Hi,

Thank you for sharing the dump file with us, and well done with the investigation on your part. We found exactly the same results as you have.

LiveUpdate.exe is not an integral Windows file. The file name is used by several tech companies, including your PC's manufacturer.

From our research and analysis, we can logically assume that LiveUpdate.exe is related the manufacturer's update program of your PC. Thus, we suggest you uninstall it via Control Panel > Programs > Programs and Features > Uninstall a Program.

Once done, you should be able to use your computer without issues. Otherwise, let us know so we can continue helping you.
