Split from this thread.


I am experiencing this issue on my home PC, upgraded from Windows 7 to 10 some months ago.

Suddently I get blue screen with "KERNEL DATA INPAGE ERROR"

I have run "CHKDSK C: /F /R", upgraded all drivers and check cables, nothing helps.

Attaching DMP file (as ZIP) and event-log from last crashes.!AlNqlsK00PjegTpB8ZYTqgOK3KFs!AlNqlsK00PjegTm6ppB8yS10L4HO

What can I do?

Thank you!

Probably caused by : Unknown_Image ( ANALYSIS_INCONCLUSIVE )

Are you using an SSD? Or RAID? Double Check "EVERYTHING" relating to the hard drive, controller, and cabling (of course remove ALL power first). If an SSD check for firmware updates with its maker's support.


Troubleshoot blue screen errors

1. Check with your system/motherboard maker for updates to Mv91xx.sys Marvell magni driver.

2. If a PC remove ALL power. Open case, remove and reseat ALL cards, memory chips, and ALL
cables (do not just try to snug) on both ends if they can be reached and on the device ends if not (removing the cables and reseating them helps to eliminate minor corrosion). On a laptop about all that can be done is to reseat the memory and hard drive. Ensure fans are working and try adding a small fan blowing into the intake). Heat can cause a fault in a single weak component even if the heat is not above normal levels.

3. File Explorer - Right Click the hard drive (usually C: ) - Properties - Tools tab - Error Checking - Check.

4. Use all the other methods below.


Troubleshoot blue screen errors

BCCode: 7A    0x0000007A

The primary causes of this error are virus/malware, drivers, memory, and disk corruption. And there can even be combinations of those so a thorough check of all is required. Added possible causes are hardware errors such as damaged motherboard or other hardware.

BCCode: 7A    0x0000007A  <-- read this link*1137.html?order=date


File Explorer - Right Click the hard drive (usually C: ) - Properties - Tools tab - Error Checking - Check.


This is my generic how to for proper driver updates :

This utility makes it easy to see which versions are loaded : Run DriverView - set
VIEW to Hide Microsoft drivers - update those without Dump in their names (and
BIOS and chipset drivers).

DriverView - Free - utility displays the list of all device drivers currently loaded
on your system. For each driver in the list, additional useful information is
displayed: load address of the driver, description, version, product name,
company that created the driver, and more.
For Drivers check System Maker as fallbacks and Device Maker's which are the
most current. Control Panel - Device Manager - Display Adapter - write down
the make and complete model of your video adapter - double click - Driver's
tab - write down the version info. Now click UPdate Driver (this may not do
anything as MS is far behind certifying drivers) - then Right Click - Uninstall -
REBOOT this will refresh the driver stack.

Repeat that for Network - Network Card (NIC), Wifi, Sound, Mouse and Keyboard
if 3rd party with their own software and drivers and any other major device drivers
you have.

Now go to System Maker's site (Dell, HP, Toshiba as examples) (as rollback) and
then Device Maker's site (Realtek, Intel, Nvidia, ATI as examples) and get their
latest versions. (Look for BIOS, Chipset, and software updates at System Maker's
site while there.)

Download - SAVE - go to where you put them - Right Click - RUN AD ADMIN -
REBOOT after each installation.

Always check in Device Manager - Drivers tab to be sure the version you are
installing actually shows up. This is because some drivers rollback before the
latest is installed (sound drivers particularly do this) so install a driver - reboot
- check to be sure it is installed and repeat as needed.

Repeat at Device Makers - BTW at Device Makers DO NOT RUN THEIR SCANNER -
heck manually by model.

Manually look at manufacturer's sites for drivers - and Device Maker's sites.   


Memory tests do not catch all errors such as mismatched memory (possible even
for sticks that appear to be identical) and when faster memory is placed in system
behind slower memory. So it is best to also swap sticks in and out to check for
those even if all memory tests fail to show a problem.

To test RAM check here - let it run 4+ hours or so.  <-- best method

MemTestX86 - Test RAM With

For the Windows Memory Diagnostic Tool.

Type in Cortana's search box ->  Windows Memory Diagnostics 
at top of list - click it. in Windows 8/8.1/10 the name is "Windows Memory


After doing ALL the updates you can, and if the issue continues, then run

Driver Verifier can help find some BSOD issues :

Using Driver Verifier to identify issues with Windows drivers for advanced users

How To Troubleshoot Driver Problems in Windows Vista or 7. (8/8.1 and 10
are essentially the same).

Using Driver Verifier

WINKEY + X - RUN - type in -> verifier /reset      hit enter to disable

Use BlueScreenView to see if there is a driver specified in the error message.
Also check with MyEventViewer at the time of the BlueScreen.

If DriverVerifier creates a minidump upload it and post the link here so we can
analyze it.

Hope this helps.
