Fix “SYSTEM THREAD EXCEPTION NOT HANDLED” BSOD Stop Code in Windows 10
Taking into account my vast experience in the IT field, what I’ve noticed is that the SYSTEM THREAD EXCEPTION NOT HANDLED error is more common for Windows 10 users, resulting in a Blue Screen of Death (BSOD)!
This usually happens when the computer fails to handle an error thrown by a process or application.
I’ve tested the below fixes with my clients…so please go ahead and try them out.
Definition Of The Error
System thread exception not handled is a type of stop code error revealed with the “Blue Screen of Death” on Windows-based systems. This error generally occurs when certain drivers are incompatible with the system configuration, causing the system to crash and display the stop code 0x0000007E or 0x1000007E.
Problems may also occur due to hardware conflicts such as memory problems or IRQ (Interrupt Request) interferences between devices. The specific issue can be identified in log files which can help users identify the device or driver associated with this error message so they can fix it automatically if possible.
System thread exception not handled errors can be caused by a myriad of things, including incompatible drivers, conflicts between hardware or software components, out-of-date or faulty firmware, outdated system files, and more.
In some cases the error provides clues about its source – for instance, the error message may include a faulty file name – but in other cases, users must determine or track down the cause themselves.
To identify the cause of such an error, it is important to take the following steps:
- Check Error Log Files: First check your computer’s error log files in Event Viewer. This step will help you locate crashes that have occurred before and identify patterns related to stop codes, warnings for specific processes or components, etc. This will assist in pinpointing potential causes of the system thread exception not handled error.
- Update/Rollback/Reinstall Drivers: If these logs reveal driver incompatibilities or out-of-date drivers, attempt to update them with compatible ones from Device Manager; if unsuccessful try rolling back those drivers; if still unsuccessful consider reinstalling them using reliable sources such as manufacturers’ websites and Microsoft Update website.
- Run Memory Diagnostics: If device drivers appear to be functioning properly yet you still experience regular crashes due to system thread exception not handled errors then consider running memory diagnostics tests from the Windows Memory Diagnostic tools utility or use online tools like Memtest86+.
- Update Firmware: To avoid conflicts between hardware components consider updating your firmware if all other steps fail to work. Before starting this process, ensure that the firmware is up-to-date and compatible with your device and operating system.
- Repair System Files: Corrupted system files can also lead to BSOD errors like system thread exception not being handled so utilize Windows 10 systems repair tool SFC tool (System File Checker) and run an “sfc /scannow” command; SFC will look for corrupted/missing system files and automatically fix any issues it finds by replacing the damaged/corrupted system files with new ones from a compressed folder located at %WinDir%\System32\dllcache\.
This error is a dreaded stop code that makes your computer unresponsive by bringing up the BSOD (Blue Screen of Death).
In addition to this, other common symptoms of this error may include system freezing, crashing applications, or frequent reboots.
When you encounter these issues on your machine it’s important to take steps to address the problem eventually to keep your computer running smoothly. Otherwise, it can cause negative consequences such as data loss or unstable system performance for an extended period.
1. Booting Into Safe Mode
One of the best ways to fix this error is by booting into Safe Mode With Networking. In safe mode, minimal hardware and software are available for your computer to function.
With fewer drivers available during start-up, there’s a lower chance of one incompatible driver causing any issues compared to a normal mode startup. This makes it easier for troubleshooting and repair errors like this one.
To enter Safe Mode on Windows: press F8 as soon as you turn on your computer before it enters the splash screen for which OS you want to boot into; when prompted make sure that only “Safe Mode” is checked off; hit enter/return key and let Windows do its thing with diagnostics.
Your desktop will then show a minimalist design showing something similar to regular windows but with basic features only and no sound effects enabled etc most likely due to missing drivers in its library while only allowing necessary fundamentals like internet access if connected via wire or wifi card.
2. Check For Conflicting Software
One of the most common causes of the system thread exception not handled error is conflicting software.
While in Safe Mode, go to Control Panel -> Uninstall programs. Remove any programs installed recently.
3. Disabling Overclocking
When overclocking insufficiently cooled processors or memory modules, heat buildup can lead to data corruption and instability in the operating system thus triggering the dreaded blue screen of death with this error message.
It’s important to note that just because a processor supports overclocking does not always mean it’s safe or even recommended to do so—especially when considering an average user who may be unaware of potential pitfalls and damage risks that come with running parts beyond their factory-approved limits.
The first step in resolving defects caused by overclocking is disabling all custom clock speed configurations made previously through BIOS settings or software applications used for tweaking hardware components like video cards and CPUs etc.
4. Updating Outdated Drivers / Roll-Back Recent Updates
These driver updates are usually released to fix security vulnerabilities, performance issues, bugs, hardware incompatibility problems, etc. You need to make sure all your drivers are up-to-date as any out-of-date drivers can lead to system instability.
Common Drivers that need updating include Graphics Card Drivers (NVIDIA/ AMD), Audio Card Driver (RealTek), HDMI Monitor & TV Driver, Network Controller / Wireless Adapter Driver (Intel/ Broadcom), Ethernet Drivers, USB 3.0/2.0 Hubs Drivers and more.
Goto Device Manager -> Right Click on all drivers mentioned above and click on update.
Now while browsing through your driver list, if you see a driver that’s been recently updated ( just before this error happened ), let’s try to uninstall/roll back that driver update.
5. Running Memory Diagnostics
Memory diagnostics can detect any issues with RAM or other hardware that may be causing the error, such as bad sectors, corrupt memory cells, loose connections, etc. To run a memory diagnostic, restart your computer and press F8 (or Your PC’s BIOS button) to access Boot Options Menu.
Select “Diagnostic Startup” from your available options and let it finish booting up. Restart again, and select ‘Advanced Options > Troubleshoot’ again in the menu option.
Go to Advanced Options> Windows Memory Diagnostics Tool. Follow on-screen instructions on how to perform the diagnostics check; once finished you should see results shown in the Test Results tab which will help you diagnose potential problems leading to system thread exception not handled error.
6. Checking For Hardware Issues
Hardware components like RAM, hard drives, and graphics cards usually cause this type of issue.
Therefore, the best way to troubleshoot this error is by running thorough hardware diagnostic tests using built-in tools or third-party software.
This will help identify any malfunctions in one or more of these components so that you can address them promptly before they become a serious problem.
7. Checking For Malware Or Viruses
Since malicious software such as spyware, trojans, worms, and a wide range of other malware can affect your system’s stability by acting as rootkits or registry hijackers that disrupt the normal operation of Windows components, it is highly recommended to run a virus scan in Safe Mode.
Anti-malware tools like Malwarebytes or Avast should do the trick!
8. Repairing System Files
Both utilities can use restore points to replace corrupted or missing Windows components, which should solve any problems related to failing driver file updates or other kinds of corruption that cause BSODs.
To run SFC, navigate to the Start Menu > Type “cmd” > Right click on cmd in the search results > Choose “Run as Administrator” > In Command Prompt type “sfc /scannow”.
The DISM tool performs more advanced repair operations than SFC; It can access online image files from Microsoft servers containing Windows Images to update corrupt system drives offline.
For an offline store scan using DISM you would need a USB drive with at least 8GB capacity, then type this command into CMD – ‘dism /online/cleanup-image/restore health/source:wim:/limitaccess/setpath::install.win’.
9. Using Windows Restore Point
Restoring your computer to another point in time can address problems caused by faulty or installed programs, driver updates, system settings, etc., but does not necessarily resolve hardware failures.
To use Windows Restore Point as part of troubleshooting this error: search for ‘Create Restore’ in your computer’s start menu; select ‘System Properties’; click the ‘System Protect’ tab, then choose a suitable restore date from those listed; and press OK.
All changes made since that date will be reversed while any fixes since then may need redoing afterwards.
10. Reinstalling Windows
You must back up any files and data beforehand as reinstalling will erase everything on your system.
To install, access the Windows installation media, select a custom or full installation type, enter your product key when prompted, and complete the steps in the guided setup process.
You’ll need to restart your computer several times during this procedure – be sure to follow all instructions carefully! Be aware of any risks associated with reinstalling, such as corrupt software or hardware issues.
Prevention Tips For The Future
1. Regularly Updating Drivers And Software
Outdated drivers or software can sometimes cause conflicts with the operating system or hardware that can lead to instability in systems, leading to an increase in errors such as this one.
Device drivers should be updated frequently since they are responsible for enabling communication between devices and the computer’s OS. Drivers need to stay compatible with any updates that are released for device firmware or for Windows itself.
Additionally, software programs should be kept up-to-date to patch vulnerabilities and fix known issues that might have previously caused a conflict with another program or service on your PC.
Generally speaking, both Windows Update Service and device manufacturer’s websites contain driver updates you can download directly
2. Using Trusted Sources For Downloads
Whenever dealing with downloads, whether it be software, drivers, or other types of system updates, it’s important to ensure that the source is reliable and verified.
Unverified sources often offer malicious files, such as viruses or trojans, which can bring more damage rather than help.
To identify trusted and safe sources for downloading always check user feedback from reviews sites like TrustPilot and ask any personal connections you have for advice before proceeding with an unfamiliar download provider.
3. Keeping System Backups
Backups can come in three forms: full system backups which back up your entire system; incremental or differential backups which save changes to files since your last backup; and file-level backups where you manually select individual files or folders for backup processing.
Depending on how often you update either type of backup, storage space requirements can vary greatly. Automation also plays an important role in creating reliable system images that can be used to restore your PC with minimal disruption should anything go wrong.
It’s recommended to use a combination of cloud-based solutions as well as external hard drives so that multiple copies are always available, ensuring you never lose any data even if files become corrupted or lost locally due to technical failures.
To ensure these processes remain robust it’s important to test them regularly – failing to do this could leave users vulnerable when faced with disruptive faults down the line.
The system thread exception not handled error can be a frustrating and alarming experience, especially for novice users. Fortunately, it is relatively easy to recognize the symptoms of this error and apply fixes with some basic troubleshooting methods.
Users should start by finding out which driver or component is causing the error before proceeding with any fix or solution.
To keep their computer safe in the future from such errors, users must also develop good habits like regularly updating drivers automatically, running system scans, or memory diagnostics as preventive measures.
