It’s unpredictable when it can happen, except for most users it always happens at boot time.

So, we are mentioning several ways (applicable to Windows 8 and 10 users) to repair this problem for users who get BSOD on startup or when it appears unexpected. And not any solution will ask you to possess Windows 8 or 10 bootable media like most of the people do not have them by default.


Here are solutions for the System Thread Exception Not Handled error in Windows 8 and 10

In order to urge Windows 8 or 10 recovery mode, follow these steps:

Solution 1


Install this free application named: WhoCrashed and run this utility to seek out out which driver is causing you the SYSTEM_THREAD_EXCEPTION_NOT_HANDLED error.

The utility output should be almost like the one below:

On Fri 2/9/2020 17:11:01 PM GMT your computer crashed
crash dump file: C:\Windows\Minidump\0206153198401.dmp
This was probably caused by the following module: atikmdag.sys (atikmdag+0xC508B)
Bugcheck code: 0x1000007E (0xFFFFFFFFC0000005, 0xFFFFF801C9BBE08B, 0xFFFFD0015ADEF128, 0xFFFFD0015ADEE930)
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 trail to the file it shows that atikmdag.sys is that the troublesome driver on behalf of me . it’s going to vary for many users.

follow these steps if you did not run the utility:

  • You must open the pc in safe mode. So, as soon as you switch on the pc , hold down the F8 function key until the OS shows you a menu of boot options.
  • Select Safe Mode and press Enter.
  • During startup or after login, once you get BSOD again, you’ll also find a file name with the System Thread Exception Not Handled error. The result seems like this: System Thread Exception Not Handled (FILENAME.sys) where FILENAME might vary for every user.

Here is a list of those FILENAMEs 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
  • Write down the name of the file somewhere.
  • Suddenly restart the pc to get Windows 8 or 10 recovery mode.
  • go to Troubleshoot> Advanced options> command prompt.
  • Run the following commands at the command prompt:
cd windows\system32\drivers

Where FILENAME is the one you wrote down within the step above. As I had the error due to atikmdag.sys, so for me the command is:

Ren atikmdag.sys atikmdag.old

  • Close the prompt and restart.
  • Now your computer should start successfully.
  • Reinstall the updated driver that caused you of these problems, if everything is functioning fine then leave it. Windows takes care of it automatically.

Solution 2

In case you’re unable to boot in safe mode, then there are other ways you’ll attempt to boot the pc successfully:
Turn it off, remove the battery, unplug it from its power source, leave it off for a couple of minutes, press and hold the power button for 5-10 seconds, connect the power outlet, BUT NOT THE BATTERY, activate the laptop. It should start normally. Then replace the battery as soon as possible. After the PC has successfully started , remove the driver that is causing the problems and restart.

In case you get the BSOD unpredictably frequently, then you should try disabling hardware acceleration within the browser and in flash. Disabling hardware acceleration for every browser is different.
