Stop errors (blue screen) in Windows
Stop errors (also called blue screen errors or blue screen of death errors) are the most severe errors Windows can encounter. They occur if a serious problem causes your Windows system to shut down or restart unexpectedly. You might see a message that says "A problem has been detected and Windows has been shut down to prevent damage to your computer".
These errors can be caused by both hardware and software issues, and it can be difficult to troubleshoot the problem. In reality, the most common cause of blue screen errors is a device driver problem. Outdated, incorrect or corrupt drivers can cause the system to encounter a Stop error. You can use a driver update program to check, find, download and update all device drivers automatically.
The following tools and methods can also help you get Windows up and running again.
What is the KERNEL MODE EXCEPTION NOT HANDLED error
The KERNEL_MODE_EXCEPTION_NOT_HANDLED bug check has a value of 0x0000008E. This bug check indicates that a kernel-mode application generated an exception that the error handler did not catch.
This Stop message indicates that the Windows kernel detected an illegal or unknown processor instruction. The problem can be due to invalid memory and access violations.
Interpreting the message
This Stop message has four parameters:
- Exception code that was not handled.
- Address at which the exception occurred.
- Trap frame.
- 0x80000002, or STATUS_DATATYPE_MISALIGNMENT, indicates that an unaligned data reference was encountered. The trap frame supplies additional information.
- 0x80000003, or STATUS_BREAKPOINT, indicates that a breakpoint or ASSERT was encountered when no kernel debugger was attached to the system.
- 0xC0000005, or STATUS_ACCESS_VIOLATION, indicates that a memory access violation occurred. Parameter 4 of the Stop message (which is Parameter 1 of the exception) is the address that the driver attempted to access.
- 0xC0000044, or STATUS_QUOTA_EXCEEDED "Insufficient Quota Exists To Complete The Operation", indicates a pool memory leak. A quota allocation attempt necessary for the system to continue operating normally was unsuccessful because of a program or driver memory leak.
Fix the KERNEL MODE EXCEPTION NOT HANDLED error
The following suggestions can help you resolve the KERNEL MODE EXCEPTION NOT HANDLED error:
Drivers or system services:
This Stop error typically occurs after you install faulty drivers or system services, or can indicate hardware problems, such as memory and interrupt request (IRQ) conflicts. If the Stop message lists a driver by name, you need to disable, remove, or roll back that driver. If not, disable the recently installed service or application to determine whether this resolves the error. If this does not resolve the problem, contact the hardware manufacturer for updates. Using updated drivers and software is especially important for backup programs, multimedia applications, antivirus scanners, DVD playback, and CD mastering tools.
In most cases the KERNEL MODE EXCEPTION NOT HANDLED error can be solved by updating the drivers for the device causing the error. Also make sure you update your Windows and antivirus software, as some of these errors are not caused by hardware, but software problems. You can use the Windows device manager to uninstall any currently installed driver for the device and reinstall the latest driver. When you reboot your PC after uninstalling the drivers, Windows will detect the new hardware, which allows you to install manually the latest drivers for the device.
If you do not have the drivers for the device in error, or are not comfortable in using the Windows device manager, you can also use a driver update program to find, download and update all device drivers for you. Driver update software will accurately identify your hardware, including the device in error, and automatically install the latest drivers for it. This can solve easily KERNEL MODE EXCEPTION NOT HANDLED errors.
If the Stop message mentions the file Win32k.sys, the source of the error might be a third-party remote control program. If such software is installed, you might be able to disable it by starting the system in safe mode. If not, use Startup Repair to manually delete the system service file that is causing the problem.
Problems can result from system firmware incompatibilities. You can resolve many Advanced Configuration and Power Interface (ACPI) issues by updating to the latest firmware.
Other possible causes include insufficient disk space while installing applications or performing certain functions that require more memory. You can free up space by deleting unneeded files (duplicate files, junk files, and temporary files). Use a cleaning tool software to increase available disk space and speed up your system.
