When Windows encounters certain situations, it halts and the resulting diagnostic information is displayed in white text on a blue screen.
Blue Screen errors occur when:
- Windows detects an error that it cannot recover from without losing data
- Windows detects that critical operating system data has become corrupted
- Windows detects that hardware has failed in an unrecoverable fashion
Windows 10 crash errors are collected in Problem Reports and referenced against other crash data that is available online. To access Problem Reports, follow these instructions:
- Click Start , then type "problem reports."
- Select View all problem reports to view a list of errors that have occurred on your computer and possible solutions for them, such as updating drivers, flashing your system BIOS, or checking for updates to software.
- Under the Source column, look for Windows and under Summary, look for Shut down unexpectedly.
- Right-click the line item and select Check for a solution.
Note: You must be online to view solutions.
Dell has created online diagnostics that can identify problems with your computer hardware or configuration that may be causing the issue. Visit the Dell Online Diagnostics to get more information and run a scan of your computer.
When a critical error is detected in Windows, your computer restarts itself to prevent any further damage.
This is a safety measure that is integrated into Windows. To further analyze the STOP error, we need to know the error code and information that is associated with the error.
This information is displayed when you turn off automatic restart. To turn off automatic restart, follow these steps:
- Click Start , then type "advanced system settings."
The System Properties window appears.
- Click the Advanced tab.
- Under the Startup and Recovery section, select Settings....
- Under System failure, uncheck the box next to Automatically restart.
- Click OK, then click Apply and OK to complete the update.
UNMOUNTABLE BOOT VOLUME
INACCESSIBLE BOOT DEVICE
These two errors have similar causes and the same troubleshooting steps apply to both of them. These stop codes always occur during the startup process. When you encounter one of these stop codes, the following has happened:
- The system has completed the Power-On Self-Test (POST).
- The system has loaded NTLDR and transferred control of the startup process to NTOSKRNL (the kernel).
- NTOSKRNL is confused. Either it cannot find the rest of itself, or it cannot read the file system at the location it believes it is stored.
Your task when troubleshooting this error is to find out why the Windows kernel is confused and fix the cause of the confusion.
Things to check
- The SATA controller configuration in the system BIOS. If the SATA controller gets switched from ATA to AHCI mode (or vice versa), Windows cannot talk to the SATA controller. These different modes require different drivers. Try switching the SATA controller mode in the BIOS.
- RAID settings. If you have been experimenting with the RAID controller settings, you may receive this error. Try changing the RAID settings back to Autodetect.
- Improperly or poorly seated cabling. Try reseating the data cables that connect the drive and its controller at both ends.
- Hard drive failure. Run the onboard diagnostics on the hard drive. Remember: Code 7 signifies correctable data corruption, not disk failure.
- File system corruption Launch the recovery console from the Windows installation disk and run chkdsk /f /r.
This stop code indicates that the NTFS file system driver encountered a situation that it could not handle, and is usually caused by 3 things:
- Data corruption on the disk
- Data corruption in memory
- The system completely runs out of memory (typically this only happens on heavily loaded servers)
Things to check
- Reseat the memory and all drive data cables to eliminate data corruption issues stemming from poorly or improperly seated hardware.
- Run a complete memory and hard drive diagnostic. The quick test is insufficient here. You must run the full system diagnostic.
- If those diagnostics pass, run a full file system check from the Recovery Console (chkdsk /f /r) to detect and (potentially) fix any corrupted data.
- If none of the above solves the issue, reinstall Windows.
- If that does not fix the issue, replace the hard drive.
SYSTEM THREAD EXEPTION NOT HANDLED
KERNEL MODE EXCEPTION NOT HANDLED
These two errors indicate that a program running in the kernel encountered an unexpected condition that it could not recover from. They have identical troubleshooting and resolution steps, and you must use the Windows Debugger to find out what caused the error.
Things to check
- If the Blue Screen message mentions a driver or library file, determine what driver or application that file is part of and update or disable it.
- Update the system BIOS to the latest available revision.
- Uninstall any recently installed programs, and roll back any recently installed drivers.
- Run diagnostics on the computer memory.
PAGE FAULT IN NON PAGED AREA
This stop code means that the system tried to access a nonexistent piece of memory, almost always due to:
- A driver trying to access a page of memory that is not present
- A system service (ex. virus scanner) failing in an exceptional way
- Faulty or incorrectly seated memory
- Corrupted data on the hard drive
Use the Windows Debugger to pinpoint the exact cause of these errors.
Things to check
- If the Blue Screen error mentions a driver or library file, determine what driver or program the file is a part of. Either upgrade to the latest version or uninstall the driver or program.
- If the error happens during the startup process, try booting to the Last Known Good Configuration.
- If the error appears after a program or driver was installed, uninstall that program or driver.
- Try running a full hard drive and memory diagnostic after reseating the memory and hard drive data cables.
DRIVER IRQL NOT LESS THAN OR EQUAL TO
This stop code indicates that a driver triedthat to access memory it should not have, meaning there is a flaw in the driver itself. The goal of your troubleshooting is to find that driver and either disable or replace it. Use the Windows Debugger to troubleshoot this error.
Without the debugger, you are limited to uninstalling/updating/rolling back the driver that contains the driver file the Blue Screen mentions.
For more information, refer to Dell article, "How to repair the Windows Blue Screen error "STOP 0x0000000A: IRQL_NOT_LESS_OR_EQUAL""
THREAD STUCK IN DEVICE DRIVER
This Blue Screen error indicates that a device driver-almost always a video card driver-is stuck waiting for something (usually a hardware operation) to happen. Most of you have probably seennv4_disp.sys associated with this Blue Screen.
Things to check:
- Ensure that the video drivers are updated to the latest Dell version.
- The system BIOS is fully up-to-date.
- If both the video driver and the system BIOS are fully up-to-date, check with the manufacturer for recent driver updates.
- As a last resort, try exchanging the video card.
Note: Reinstalling Windows is not likely to prevent this error from recurring.
BAD POOL HEADER
A BAD POOL HEADER error indicates that your computer is not allocating memory correctly. This is usually caused by a bad driver, but can sometimes be caused by software or faulty memory. To remedy this issue, try the following steps:
- Update all drivers to the latest version.
- Update any software used at the time of the crash.
- Visit the Dell Online Diagnostics to run a scan of your computer memory.

The Microsoft Bug Check Code Reference
site has an extensive list of blue screen error codes descriptions and possible causes. If you have recorded your STOP 0xXXXXXX code and the above steps have not resolved your issue try looking it up on this site.
If the previous troubleshooting could not resolve your issue, it may be necessary to restore your computer to factory settings. To restore your operating system and software to the original factory settings, refer to Dell Knowledge Base article, "Reset or reinstall Windows 10 on a Dell computer"
