[Fix] System Thread Exception Not Handled BSOD Error in Windows 8 and 10

System Thread Exception Not Handled Blue Screen of Death (BSOD) is a widespread problem among Windows 8 and Windows 10 users. And could occur anytime while start-up of Windows or while doing any random work. It’s unpredictable when it can occur, but for most users, it usually happens at boot time. So we are mentioning several ways (applicable to both Windows 8 and 10 users) to fix this issue for users who get BSOD at start-up or when it appears unpredicted. And any of the solutions will NOT require you to have bootable media of Windows 8 or 10 as most users don’t have these by default.

Solution For System Thread Exception Not Handled in Windows 8 and 10

We have already written a solution to the Windows 10 Blue Screen of Death (BSOD) and Internal Power Error. You should read this first before trying below the given solutions.

Windows 8 and 10 have an inbuilt recovery, and if you run into any start-up issue during boot of OS, it’ll show up offering you options to fix your computer. But the question is, how to reach those options. Many people suggest using a Bootable CD or USB for windows, as they help to get users the same tools with convenience, which are already there is an operating system recovery system. So, to get into recovery mode of Windows 8 or 10, do the following steps:

[Fix] System Thread Exception Not Handled BSOD Error in Windows 8 and 10[Fix] System Thread Exception Not Handled BSOD Error in Windows 8 and 10

  • When you get BSOD, just close the PC using the power button, press it continuously till it gets switched off.
  • Power ON and OFF it abruptly when the Windows logo appears during the boot process. Repeat this 3-4 times, until windows show you various recovery options.
  • Assuming you reached the Windows 8 or 10 recovery options, go into Troubleshoot > Advanced Options > Command Prompt.
  • Run following command in it:

sfc /scannow /offbootdir=c:\ /offwindir=c:\windows

  • It’ll find some errors but shall not be able to fix all. Also, run the following command then:

<span class="bb-bold">bcdedit /set {default} bootmenupolicy legacy</span>

  • Now close the command prompt and reboot the computer.

Find the Driver Which is Causing You Trouble

  • Install this free application named: WhoCrashed and run this utility to find out which driver is causing you SYSTEM_THREAD_EXCEPTION_NOT_HANDLED BSOD error.
  • The output of the utility should be similar as below:
On Fri 2/6/2015 7:56:50 PM GMT your computer crashed
crash dump file: C:\Windows\Minidump\020615-31984-01.dmp
This was probably caused by the following module: atikmdag.sys (atikmdag+0xC508B)
Bugcheck code: 0x1000007E (0xFFFFFFFFC0000005, 0xFFFFF801C9BBE08B, 0xFFFFD0015ADEF128, 0xFFFFD0015ADEE930)
Error: SYSTEM_THREAD_EXCEPTION_NOT_HANDLED_M
file path: C:\Windows\system32\drivers\atikmdag.sys
product: ATI Radeon Family
company: Advanced Micro Devices, Inc.
description: ATI Radeon Kernel Mode Driver
Bug check description: This indicates that a system thread generated an exception which the error handler did not catch.
This appears to be a typical software driver bug and is not likely to be caused by a hardware problem.
A third party driver was identified as the probable root cause of this system error. It is suggested you look for an update for the following driver: atikmdag.sys (ATI Radeon Kernel Mode Driver, Advanced Micro Devices, Inc.).

If you check the file path, it shows that atikmdag.sys is the troublesome driver for me. It can vary for most users.

Or if you’re not in a condition to run the utility, then do the following steps:

  • Now you need to open the computer in Safe mode. So, as soon as you turn ON the computer, keep pressing the F8 function key along with it, until the OS shows you a menu of boot options.
  • Select Safe Mode and Enter.
  • During the boot or after login, when you get BSOD again, you’ll also find a file name along with System Thread Exception Not Handled. The output would be like System Thread Exception Not Handled (FILENAME.sys) where FILENAME could vary for users.

Following is a list of those filenames along with the associated driver:

atikmdag.sys - AMD Display Graphics Driver

ATI2DVAG.sys - AMD Display Graphics Driver

ATI2CQAG.dll - AMD Display Graphics Driver

ATIVPK.sys - AMD Display Graphics Driver

AMD2DVAG.sys - AMD Display Graphics Driver

AMDKMDAG.sys - AMD Display Graphics Driver

AMDVPK.sys - AMD Display Graphics Driver

iaStorA.sys - Intel Rapid Storage Technology Driver - x64

wificlass.sys - Cisco wireless Access Points
  • Note down the file name somewhere.
  • Reboot and again you to abruptly restart the computer to get into the recovery mode of Windows 8 or 10.
  • Navigate to Troubleshoot > Advanced Options > Command Prompt.
  • Run following commands in the command prompt:
c:
cd windows\system32\drivers
ren FILENAME.sys FILENAME.old

where FILENAME is the one you noted in the above step. Like I had an error because of atikmdag.sys, hence for me the command is:

ren atikmdag.sys atikmdag.old

  • Close command prompt and Reboot.
  • Now your computer should boot successfully.
  • Re-install updated driver who caused you all this trouble or everything is working fine, then leave it. Windows shall automatically take care of it.

Solution 2

In case, you’re not getting success in reaching safe mode, then maybe you can try this way to boot computer successfully:

Turn it off, remove the battery, unplug it from its power source, leave it off a few minutes, hold down the power button for 5-10 seconds, plug power back in BUT NOT THE BATTERY, turn on the laptop. It should start normally. Then put the battery back in at your earliest convenience. Once PC boots successfully, remove that driver, which is causing you trouble and Reboot again.

In case if you get BSOD in an unpredicted manner frequently, then maybe you should try disabling hardware acceleration in browser and flash. Disabling hardware acceleration for every browser would be different.

Disable Hardware Acceleration in Chrome

  • Open Google Chrome.
  • Type in chrome://flags in the address bar and Enter.
  • Scroll down and navigate yourself to “GPU compositing on all pages.”
  • Select “Disabled” from the dropdown. It would be “Default” by default.
GPU composting on all pages
  • Click Relaunch Now. Chrome will close and restart.

Disable Hardware Acceleration in Mozilla Firefox

  • Open Mozilla Firefox
  • Type in about:preferences#advanced in the address bar.
  • Uncheck “Use hardware acceleration when available.”
Disable Firefox Hardware Acceleration
  • Close and Restart Firefox.

Disable Hardware Acceleration in Internet Explorer

  • Open Internet Explorer
  • Click Tools > Internet Options
  • Select “Advanced” and under “Accelerated graphics,” checkbox “Use software rendering instead of GPU rendering.”
Disable Flash Hardware Acceleration IE
  • Apply and OK.
  • Restart Internet Explorer.

Disable Hardware Acceleration of Adobe Flash Player

  • Scroll down to Step 5 that has an animated tree embedded flash object.
  • Right-click on the animation and select “Settings.”

Adobe Flash Player Settings

  • The dialog box of Adobe Flash Player Settings would open.
  • Uncheck “Enable Hardware Acceleration.”
Disable Flash Hardware Acceleration
  • Close
  • Restart the Browser.
  • Repeat the steps with other installed browsers.

Hopefully, now you should not get the Blue screen of death again on your computer with Windows 8 or 10. If you encounter any issue, please ask in comments. Below is a video with additional ways to confront this issue:

    • If you’re using a 64Bit OS and facing this issue, you can run BCEDIT from following path:

      C:\Windows\Sysnative\bcdedit

      OR

      You should check if your BCEDIT is damaged or not. For doing so, run following command in command prompt:

      sfc /VERIFYFILE=C:\windows\system32\bcdedit.exe

      If the file is fine, you should get output like this:

      Windows Resource Protection did not find any integrity violations.

      or if the file is damaged, then either running a complete system scan should bring back BCEDIT command:

    • Then your problem should be temporary or your RAM could be faulty or there could be errors in hard disk. If you have multiple physical RAM, then swap their slots. Or you must update your windows with all latest updates. No file name means you’re not facing this issue because of any software driver.

    My Toshiba computer keeps giving me this BSOD. After I got it, I turned my computer completely off. Now when I try to turn it back on(tried multiple times), the only thing that comes up is the light from the keyboard and not the screen. It keeps turning on and off by itself when I don’t even touch it. Got any idea on how to fix this? (I unplugged it from the wall and tried it and took off the battery. I even tried to wait some time and do it, but there was no luck.)

    Thanks in advance!

  9. Hello, I have had experienced the same problem and this helped me a little, I have just gotten to the command prompt and ran the first command. However, during the process of scanning, it stated that there is a system repair pending that requires reboot to complete. And wants me to restart Windows and run the process once more, even though it will just loop back to the system repair pending. I am at a dilemma on what to do now, and would like some help on this. Should I try to override (if I even can) the system repair or what? Please reply as soon as you are able to. Thank you for taking the time to read this, and if the problem had been resolved, thank you for helping me.

    • Hi Freddie, apologies for late reply. I did a bit of research on your issue and found that BSOD in your computer is being caused by any software installed of “NCH software,” probably “SoundTap Streaming audio recorder” or could be anyone else. Hence, uninstall that software, run a registry cleaner via software like CCleaner and your problem should be solved.

      • Fix Nvidia Nvlddmkm.sys Error Message

        Go to your NVIDIA folder (located in C:\NVIDIA), and look for the file named nvlddmkm.sy.

        Next, copy the file at the root of C:. In most cases, this file name is C:\nvlddmkm.sy_.

        Now, head to the system folder that houses your drivers (in many cases, this is C:\Windows\System32\drivers\).

        Locate the nvlddmkm.sys file, and rename it as nvlddmkm.sys.old.

        Now, open the command prompt by pressing the Windows key + R and typing cmd.

        Type cd, followed by the Enter key. Then, type expand.exe nvlddmkm.sy_ nvlddmkm.sys, and press Enter again.

        This command will allow you to unzip the nvlddmkm.sys file (which was previously saved at the root of C:) and create a new file instance.

        Copy the new file to C:\WindowsSystem\32drivers, and then restart your PC to let the changes take effect.

        • Hi Robert, thanks for your reply. It took me some time to figure things out, but this is how it went down.
          The file NVLDDMKM.SY_ was found in C:\ProgramFiles\NVIDIACorporation\Installer2\Display.Driver.0. I copied the file to the root of C:, but was unable to expand it there (not able to open output file). I moved it to another directory and that worked.
          In C:\Windows\System32\Drivers there was no NVLDDMKM.SYS, so nothing to rename. I copied the expanded file into that directory and restarted the PC.
          After a few hours the blue screen came back and since then a number of times.
          When I perform a search on my C: drive for the file NVLDDMKM.SYS I get 23 results. One of them is the file in C:\Windows\System32\Drivers (Version 8.17.12.7533 of 2011), the other 22 are located in 22 different directories, all starting with C:\Windows\System32\DriverStore\FileRepository and then for example nvmowu.inf_amd64_a9c3add7483ca8dd or nvpcdwu.inf_amd64_995a4ef70644e93e (all Version 21.21.13.6909 of august 27 2016).
          Any thoughts on that ? Should I replace them all ?

    • You must have a Broadcom Wireless 802.11ac adapter in-built. Either get latest drivers of that wireless adapter, directly update it from device manager or check official website of your laptop brand or of Broadcom. If still the issue persists, disable inbuilt wireless adapter, and buy a USB wireless adapter from the market. You’ll get a new one of D-link, Netgear (preferred) or Tp-Link at dirt cheap price.

    • Check your memory

      The ntoskrnl.exe BSOD is usually related to memory so you might need to simply replace your RAM. Take out each stick of RAM one by one and try to boot your system, this may help you find the faulty memory but the lot might need replacing.

      Overclocking

      If you’re overclocking your system with a higher CPU clock speed, put this back to normal as it might be causing problems.

      Update drivers

      If you have a RAID setup of disk drives, update your drivers. Also update other drivers for hardware as this problem can be caused by drivers not matching the OS.

      • Hi I am literally having the same issue as this person. I am going to replace all the ram with new ram to test it out. I am currently not overclocking and I have updated all my drivers. I have had many different bsod with different codes such as PFN_List_corrupt and more commonly KMODE_EXCEPTION_NOT_HANDLED. Every time I try and find a solution different people tell me its my drivers. Ive checked and double checked and triple checked and attempted to update all my drivers and everyone says they are up to date. I just bought its computer and I have had nothing but trouble with it. Running games and it crashes the games mid way through with no error. The games just say not responding and crash. CSGO cant run above medium settings because it will just instantly crash on loading screen. And I know this PC can run everything on high. I dont know if an overwhelm of the ram or bad ram could cause all of this but it would be great to hear back from you. Also, my event viewer has been giving me errors for nvraid and also hdd saying there is bad blocks. Any help would be great.

  16. Hi Robert. First of all, thanks for this posting. I have the same issue now with Windows 10 – 64 and in my case it says “SYSTEM_THREAD_EXCEPTION_NOT_HANDLED (lvrs64.sys). I been in Contact with Microsoft support 3 times as I pay for premium support. But unfortunately it has not been that premium. I tried to solve it myself as well. Microsoft claim this is due to web cam driver and/or graphic card driver. I uninstalled both drivers and updated them, but I still enounter the same problem.

    I do get a feeling that this BSOD is more likely to happen when I use Skype and Facebook or Youtube at the same time. So far I updated Windows 10, got new graphic card drivers from Dell and new cam drivers from Logitech. Any suggestions and other things I should check or do?

    Cheers!

  17. It did repeat several times these past Days. But finally I found out that it is the Logitech cam driver that cause this issue. I been in Contact with Microsoft and Logitech.

    • Ha20x22k.sys is a type of SYS file associated with Sound Blaster X-Fi Technology developed by Creative Technologies Ltd. for the Windows Operating System. So, probably you don’t have internal sound driver latest or the driver of any additional sound card is your issue. If you’re using an additional sound card, remove that temp until you found the latest driver of it to install. Try and let me know, if you face any error further.

      Also, try changing your RAM if possible, or test it by borrowing it from some friend for a while.

      Uninstall your antivirus program & graphics driver and see if BSOD appears again.

      Update your BIOS to the latest driver if possible.

      Disable HDD S.M.A.R.T. Capability in BIOS options if this setting is enabled.

      If BSOD issue resolves, ensure to install the updated graphics driver and any other antivirus app.

  27. Hey Robert, thanks for your comprehensive article. I’ve started getting BSOD on boot with my windows 10 desktop. I can’t get it to boot, not even in safe mode. I tried all your steps and everything checks out fine, sfc verifies everything and bcdedit works without complaint. Startup repair however fails saying it couldn’t repair.

    My BSOD doesn’t ever list a filename so I ran memtest86 v7.3 and it’s 3 passes in with no errors, so I’m inclined to think my ram is fine. I took out my graphics card so the only thing attached are hard drives, my keyboard, and a monitor. What would you suggest doing next? I feel like there’s almost nothing left for me to do but wipe and reinstall – I’m normally very good at fixing computers but I’m stumped at the moment.

    • I think your hard disk has got some bad sector or has failed. If PC is not even booting, then definitely either OS is gone or the hard disk. Wish the reason is the former not later. If you fail to start the setup of windows, definitely hard disk has got some issues here.

  30. None of the solutions seem to be helping my problem.
    My file that is being given is FLTMGR.sys
    The command in solution 1,
    c:
    cd windows\system32\drivers
    ren FILENAME.sys FILENAME.old

    Does not even work in the command prompt. I’ll really appreciate some assistance.

  32. If the problem persists even after a clean driver installation (in my case drivers for my GeForce 940MX) with drivers confirmed to be working correctly should i replace my laptop?

  33. for solution 1:bcedit /set {default} bootmenupolicy legacy

    is it typo as ‘bcedit” is not recognized as an internal or external command, operable program or batch file. You said You should check if your BCEDIT is damaged or not. For doing so, run following command in command prompt:

    sfc /VERIFYFILE=C:\windows\system32\bcdedit.exe

    If the file is fine, you should get output like this:

    Windows Resource Protection did not find any integrity violations. For me it says windows resource protection could not perform the requested operation

  35. Hello! It seems that the thing causing my computers error is ntkrpamp.exe. Could you please tell me what to do next, I’ve tried using CMD, but the command “cd windows\system32\drivers” won’t work?

    • You might not like this idea but copy this file ACPI.sys from someone else PC and replace it with the one you’ve on your PC. Yours might have got corrupted or you might find it empty – 0kb size.

  36. I’m confused, because when I check my drive, no error found.

    I got this blue screen only when playing one of the game on steam, usually I’m playing a game with photoshop, illustrator, and around 20 tab Google Chrome, I’m playing a game while working. lol.

    Although I opened a big PSD files, my PC running smoothly, no lag, and the fps on the game is still great too. Nb: I’m using high spec PC, no problem with my hardware.

    I never got a problem if not open this game, I tried to open this game without another application running, I still got a blue screen.

    What do you think Sir, the problem is the game? so my PC is fine?

    Btw, thank you for share this article, really helpful for newbie like me.

    • It’s difficult to say but maybe drivers clash when you run both programs. Better don’t run both at the same time.

      • Right-click Windows key and select Device Manager.
      • Expand the Audio inputs and outputs section. You should see the Microphone and Speakers device drivers.
      • Right-click on each of them and select Uninstall.
      • Then reboot the system.
      • Re-open Device Manager as explained above and click Actions tab at the top of the screen.
      • Select Scan for Hardware changes.
      • When the scan results are ready, click Install driver. The system should detect the latest Realtek High Definition Audio drivers compatible with your OS and install them.
      • Repeat the same steps with the Bluetooth module drivers.

      If above steps doesn’t help, stop using the bluetooth speaker you’ve with your PC and try using some other bluetooth speaker and see if it happens again.

  38. I keep getting bsod for atikmdag.sys.
    Tried the steps above. I uninstalled the drivers, cleaned reg entries, reinstalled to the latest but still. I disabled any use of hardware acceleration in software that i use but still, bsod.
    I downloaded stressing/testing software but no bsod while testing/stressing. The bsod started shortly after a windows update a couple of months ago. I used to have the graphics card overclocked but never overheated nor i noticed any thermal throttling.
    Also, the bsod is kinda predictable. It usually happens if i play renpy games and have youtube playing too. Sometimes happens if i only have renpy open or only youtube.
    Is there anything i can do? Do i need a different graphics card?
    Windows 10 v1709
    AMD Phenom II x4 955
    ATI R7 240 1GB VRAM
    12GB DDR3 RAM OCZ

    • I would start with RAM first. It could be faulty! Borrow RAM from a friend/relative for few days and see if it make any difference. If it doesn’t, then restore your RAM and take out your graphics card for few days and then observe. I am sure any from the both could be faulty.

  39. I’m getting stuck on the first step I type in the scan now but it just says Windows resource protection could not start the repair service. So then I did a full scan and it got to the verification phase and came back with Windows resource protection could not perform the requested operation.

  40. Hi,

    I noticed that this might be a dead place (last comment is from last August), but I think it is worth a try.
    So, I have similar problems as you guys here, but I could not find the the codes amongst the comments I have trouble with.
    First one is “ntoskrnl.exe”, the second one is “dxgmms2.sys”. I tried to solve the bug by doing the first two solution, as it is in the description. I used the dxgmms2.sys to that, and after the steps even the Windows could not even loaded properly, I got the system recovery options. As I did not have any other ideas, I recovered the system. Unfortunately it did not solve the problem. If anyone saw this problem with these exact codes – and knows the solution – please answer me. Thank you!
