Solution 1

Windows 10 inbuilt recovery mode

If unfortunately, system thread exception not handled occur during boot Timex your computer will provide you with an option to fix your computer. Although you have an option to fix your computer right away, there is not an indicator to go to that particular option so how do you go into that option? In this case, bootable media comes in handy, and many people suggest that but we have an alternate way of fixing this issue without the use of bootable media, and that is the recovery mode.

  1. When a system thread exception occurs, you need to turn off your computer from the power button. The real deal is to keep pressing the power button until the screen turns off completely.
  2. Now you have to power it on again, but when the windows logo appears in the bootup, you have to abruptly power it on and off until the recovery option shows up.
  3. Go to the recovery option in windows 10, and you have to navigate your way to troubleshoot >advance option >command prompt.
  4. Now, this step is when it gets more technical, so you have to be very careful with it. Type the following command and run it.
  • sfc /scannow /offbootdir=c:\ /offwindir=c:\windows

This command will likely detect all the problems which are occurring the error and fix it. If the problem does not get fixed then run the following another command.

  1. There are few tools for windows 10 which can detect the driver which are causing multiple errors including the error we are looking for. So, download the application to detect the driver. I would suggest you to download an application called “WhoCrashed” which is probably the best in business.
  2. Well, the application works by showing you some command utility, and if it shows sysin the file path, then it is the troublesome driver.

Some users may not be able to run such utility, so I would suggest you to ignore the upper method and follow the guide below.

  1. When you turn on the computer, keep pressing F8 while booting up. The screen will show a menu of boot options eventually if keep pressing F8.
  2. You have to switch your computer to safe mode and by going to menu options and then selecting Safe Mode and pressing enter.
  3. When you get BSOD or System Thread Exception not handled the error, your screen will show an output with a blue background. The output will be like “system exception not handled (Filename.sys). The filename will vary with different users.

So here are some filenames

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
