This guide details how to fix the UNEXPECTED STORE EXCEPTION blue screen (BSoD) error in Windows 10, which computer and laptop users experience from time to time.
The error manifests itself in different ways: sometimes it appears at each boot, sometimes after shutting down and turning it on, and disappears after the next reboot. There are other possible ways to get the error.
Before proceeding with the following methods for fixing the error, and if it began to manifest itself recently, and before that everything was working properly, check if your computer has restore points to quickly roll back Windows 10 to a working state, see.
Among other common causes that cause the UNEXPECTED STORE EXCEPTION error to appear in Windows 10, the following stand out.
Antivirus not working properly
If you have recently installed or updated your antivirus (or updated Windows 10 itself), try uninstalling your antivirus if your computer is able to start. This is seen, for example, for McAfee and Avast.
Video card drivers
Strangely, non-original or uninstalled video card drivers can cause this same error. Try updating them.
At the same time, updating does not mean clicking "Update drivers" in the device manager (this is not an update, but checking for new drivers on the Microsoft website and on the computer), but it means downloading them from the official AMD/NVIDIA/Intel website and installing them manually.
Problems with system files or hard drive
If there are any problems with hard drive computer, as well as damage to system Windows files 10, you may also receive an UNEXPECTED_STORE_EXCEPTION error message.
Additional information that may help fix the error
Finally, some Additional Information, which may be useful in the context of the error in question. These options are rare, but possible:
- If blue screen UNEXPECTED_STORE_EXCEPTION appears strictly on schedule (after a certain period of time or clearly at a certain time), study the task scheduler - what is running at this time on the computer and disable this task.
- If the error only appears after sleep or hibernation, try either disabling all sleep options, or manually installing power management and chipset drivers from the laptop manufacturer's website, or motherboard(for PC).
- If the error appeared after some manipulations with the mode work hard disk (AHCI / IDE) and other BIOS settings, registry cleaning, manual edits in the registry, try returning the BIOS settings and .
- Video card drivers are a common cause of the error, but not the only one. If there are unknown or buggy devices in Device Manager, install the drivers for those as well.
- If an error occurs after changing the boot menu or installing a second operating system on the computer, try to restore the OS bootloader, see .
I hope one of the methods will help you fix the problem. If not, you can try resetting Windows 10 as a last resort (assuming the problem isn't caused by a faulty hard drive or other hardware).
This article is the first in a series on Blue Screen of Death errors translated from English. (Blue Screen of Death). The Blue Screen of Death (BSoD) is the error screen you see when Windows has a serious problem. It stops the PC and displays very important information.
BSoDs are much more common in Windows XP and Windows Vista than Windows 7, but still occur in all three operating systems ah (and Windows 8 too!)
Depending on the error message you need to fix, there will be different steps. So I'm going to go through each possible error message separately.
Error name:
UNEXPECTED_KERNEL_MODE_TRAP
UNEXPECTED KERNEL MODE TRAP is related to a piece of PC hardware or component, or is completely inconsistent or conflicting with another component or component.
Your Steps:
- Write down trap codes
- Check out the codes
- Download the latest known configuration
- Delete hardware
- Get Driver Reviver
- stop overclocking
These are multiple digit codes with an X in it that appear on BSoD screen next to the above phrase.
Check the codes on this site for more detailed information about what they mean. This is a high tech page Microsoft, but the information here may tell you if the problem is memory related.
Press Ctrl + Alt + Del to restart your computer, then press F8 until the Windows logo appears. Select Last Known Working Configuration, which will start Windows with a set of options that worked correctly last time. See if it helps. If so, then it could be that you may have recently installed something that could be the culprit for your problem.
Remove any hardware you may have recently installed, such as cards, USB devices, or memory. If your computer is working properly, this may be malfunctioning.
Download, install and run . You may need to restart your computer in Safe Mode with Networking (restart your computer, then press F8 and choose Safe mode using the network). Install Driver Reviver sys and update all your computer drivers to the latest version. This may fix the hardware conflict issue.
If you have overclocked your PC or laptop, which means that you have deliberately tested the speed beyond the recommended limits, this error can occur. Unfortunately, some PCs cannot be overclocked.
Good luck! Come back soon to receive additional errors BSoD and their explanations. Write your comments!
2. Video solutions for Windows 8/8.1/10
The “Unexpected Store Exception” error is quite rare in the Windows 10 operating system. Usually, the causes of the problem are corrupted system files, hard disk or memory, software conflict, incorrect installed drivers. To fix this error, you can use the system tools.
Fixing the "Unexpected Store Exception" Error in Windows 10
First, try to clean the system from unnecessary garbage. This can be done with built-in tools or with the help of special utilities. Also worth deleting recently installed programs. Perhaps they are the cause of the software conflict. An antivirus can also cause a problem, so it is also advisable to remove it, but the uninstallation must proceed correctly so that no new problems appear in the system.
Method 1: System scan
By using "Command line" you can check the integrity of important system files, as well as restore them.
Method 2: Checking the hard drive
Integrity hard drive can also be checked via "Command line".
Method 3: Reinstalling drivers
The system may automatically update the drivers, but they may not be suitable or not installed correctly. In this case, you need to reinstall them or update them. But first, turn off auto-update. This can be done in all editions of Windows 10 except Home.
- Clamp Win+R and type
Click "OK".
- Follow the path "Administrative Templates" - "System" - "Device Installation" — "Device Installation Restrictions"
- Open "Prohibit installation of devices not described...".
- Select "Included" and apply the settings.
- Now you can reinstall or update the drivers. This can be done manually or with the help of special tools and programs.
If none of the options helped, then try using a stable "Restore Point". Also check the OS for malware using the appropriate utilities. As a last resort, you need reinstalling Windows 10. Contact specialists if you cannot or are unsure that you can fix everything yourself.
0x0000007F indicates that the Intel CPU generated an interrupt that could not be captured by the kernel.
This interrupt can be a linked interrupt or a double fault. Interrupt bound - An interrupt that is not allowed to be captured by the kernel.
UNEXPECTED_KERNEL_MODE_TRAP options:
The first parameter of the blue screen specifies the interrupt number.
The most common interrupt codes are:
- 0x00000000, or divide-by-zero error. Occurs when a DIV statement is executed with a divisor equal to zero. The cause of the error may be memory corruption, hardware problems, or software bugs;
- 0x00000004 or overflow. Occurs when the processor makes a call to an interrupt handler while the overflow flag (OF) is set;
- 0x00000005 or boundary check failed. When executing the associated instruction, the processor determines that the operand exceeds the specified limits;
- 0x00000006 or invalid opcode. Occurs when the processor tries to execute an invalid instruction. The error usually occurs when the command pointer is corrupted. The most common cause of the error is hardware damage to the RAM;
- 0x00000008 or double failure. Points to the exception at the time the handler called the previous exception. Typically, these two exceptions are handled sequentially. However, there are a few exceptions that cannot be handled sequentially, in which case the processor signals a double fault. There are two main causes of double failure: kernel stack overflow and hardware problems.
Less common interrupt codes are:
- 0x00000001 - call the system debugger;
- 0x00000003 - debugger breakpoint;
- 0x00000007 - coprocessor hardware instruction without an existing coprocessor;
- 0x0000000A - TSS corruption;
- 0x0000000B - access to a non-existent memory segment;
- 0x0000000C - access to memory outside the stack limit;
- 0x0000000D - Protection failure, application access violation.
Cause
Stop 0x0000007F usually occurs after installing defective or inconsistent hardware (most commonly RAM) or if the installed hardware has stopped working.
A double failure can occur when the kernel stack overflows. This overflow occurs when drivers are repeatedly attached to the same stack.
Decision
Troubleshooting: If you have installed new hardware in your computer, you must remove it. If existing hardware is causing the failure, then you must remove or, if necessary, replace the failed computer components.
Scan RAM for errors.
Make sure all computer components are installed properly. Clean adapter contacts.
Update the BIOS.
Everybody hard disks, controllers hard drives and SCSI adapters must be compatible with installed version Windows.
If a driver is identified in the error message, disable or update that driver. Disable or remove any drivers or services that have been recently added. If an error occurs during Windows boot, and system partition formatted with file system NTFS, use Safe Mode to reinstall or remove the defective driver. If the driver is used as system process launch in safe mode, start the computer using the Recovery Console to access the file.
Restart your computer and press F8 in the text mode menu to display options for booting the operating system. AT this menu select Load Last Known Good Configuration. This option is most efficient when adding only one driver or service to the system at a time.
Overclocking CPU may cause an error. return value clock frequency CPU by default.
Make sure the system is logged into Event Viewer. The error information there will help you identify the device or driver that is causing the 0x0000007F death screen.
Disable BIOS memory caching.
If the UNEXPECTED_KERNEL_MODE_TRAP error appeared when upgrading to a new operating system version Windows systems, then it can be called by a device driver, a system service, antivirus program or program Reserve copy which are incompatible with the new version. Remove all third-party device drivers and system services, disable anti-virus programs.
Install the latest Windows Service Pack.
If the previous steps did not solve the problem, take the motherboard to a repair shop for diagnosis. Cracks, scratches, or defective components on the motherboard can cause this error.
Catching a blue screen of death in Windows 10 right in the middle of a workflow is a very sad thing. Even worse, when there are no obvious ways to solve them or a sensible explanation for the error that has arisen. The Blue Screen of Death Unexpected Store Exception is one such error. In this article, we have put together a few tips that will help you navigate and try to fix the Unexpected Store Exception error on Windows 10.
What does the stop code Unexpected Store Exception mean
The problem with this and a dozen other blue screens is that their error codes are often not meaningful to ordinary user virtually nothing, and sometimes even the opposite is misleading. Despite the word "Store" in the error code, it has absolutely nothing to do with the Microsoft Store. Shop errors often do not lead to blue screens of death. In short, there is very little information about the meaning of this error. There is no sensible explanation even in the Microsoft documentation. If you know technical essence the origin of this error, tell us about it in the comments. We turn now to known effective solutions to the problem.
How to Fix Unexpected Store Exception
Try to analyze the symptoms first. If you can pinpoint exactly when the blue screen of death appears, wait for it to appear and then look in the Scheduler Windows jobs and view its contents at the given time. From there, already navigate what to do next, depending on what the Task Scheduler tells you. If the error is random and you can't trace the dependencies, go to the tips below.
Recovery points
Check for dots Windows recovery 10. If you have several previously saved points, try to roll back to them. You may be able to roll back one of the non-obvious changes that caused Unexpected Store Exception errors this way. and all related mechanisms are described in detail in a separate article on our website.
Quick launch
If there are no restore points or rolling back to a non-earliest point did not help, try disabling fast startup. Fast Startup is a nice feature (hibernation option): it makes the computer turn on much faster. Sometimes, during a quick startup, the system does not load some of the drivers, which causes a blue screen of death with an Unexpected Store Exception error.
Understanding that the reason is a quick start can be quite simple. Complete forced reboot computer (hold down the power key until it turns off) and start it back. If fast startup is the cause, the blue screen of death will not appear until the next shutdown or reboot in the usual way. Disable fast startup as follows:
Also try preventing your computer from going to sleep. Click Windows + X and choose Power management. Prevent your computer from going to sleep. 
Problem drive
If you are still reading this article (because the methods above didn't help or just out of curiosity), move on to diagnosing your hard drive. Sometimes a blue screen of death with an Unexpected Store Exception error can appear due to drive errors or its rapidly approaching death. Make sure you have , as well as . For this you will need free utility CrystalDisk Info, and how to use it, you can learn from the link above. If an application reports an excessively high temperature or poor health of the drive, it makes sense to consider changing the media.
Ideally, if there is such an opportunity, of course, try to temporarily replace the disk with another one and observe the operation of the computer. If this is not possible, or if the diagnostic utility does not show cause for concern, check the disk for errors, as well as the integrity of system files.
- Click Start and type cmd. Click right click click on Command Prompt and select Run as Administrator.
- Enter command chkdsk/f/r. This command will check the disk for errors. The system will tell you that you can't check for errors right now because the disk is busy. Click Y and restart your computer. The check will be performed at system startup.
- After starting, launch the Command Prompt as Administrator again and enter the command sfc/scannow. Wait for the procedure to complete. Command line will tell you one of three options: no errors found, errors were found and successfully fixed, errors were found but not fixed.
- If the errors were not corrected, enter the command findstr/c”” %windir%\Logs\CBS\CBS.log>"%userprofile%\Desktop\sfclogs.txt” . Examine the contents of the log. If its contents are not clear to you or you do not know what to do with it, the best thing to do is to simply try to reinstall Windows.
Desktop PC owners can also be advised to check the connection of the drive to the motherboard and to the power supply. Make sure the cables are tight in place and don't get loose.
Antivirus
Antivirus software works at a very low level and has access to almost every corner of your computer system. Therefore, any jamb in the antivirus code can lead to very sad results, including the Unexpected Store Exception error. Try temporarily disabling the antivirus or completely disable it, and then work with the computer. Don't worry, you won't get viruses. When disabling third-party antiviruses, the built-in Windows Defender, which is enough for the eyes for about 101% of ordinary consumers. If the blue screen of death still appears, return the antivirus back to working condition. If the error no longer occurs, contact technical support your manufacturer. Perhaps they can tell you what's wrong.
Graphics driver
First, try updating to new version. AMD Drivers, Intel and Nvidia are not updated from the Device Manager, but from their respective control panels. If you notice errors appearing after a recent driver update, try previous version. Perhaps the developers made a mistake in the new release, due to which your computer suffered. Alternatively, you can try to uninstall them and reinstall the same or previous version.
Unexpected Store Exception is a very murky error. The reason for its occurrence can be not only a bad video card driver. Look in Device Manager ( Win+ X – Device Manager) and make sure it doesn't have unknown devices with yellow exclamation points. Also make sure you have downloaded, installed and updated on latest version motherboard chipset drivers, as well as BIOS.
It is said that the Unexpected Store Exception error can also appear when bootloader configurations fail. For example, when using two operating systems on one computer. In that case, try .
Traditionally, we conclude this article with a universal tip for diagnosing and troubleshooting computers on Windows 10: reinstall Windows if all else fails. Sometimes mistakes are like needles in a haystack, which only helps to catch complete reinstallation systems. Sad but true.
