BSOD K Mode Exception Not Handled

Hi all

Earlier this week I upgraded to windows 10 and was enjoying it until an error kept crashing my computer at first I just blamed it on how new windows 10 was and soon it would be fixed but then the crashes have got more and more frequent to the stage I can
use my computer for 15 mins until it crashes and goes into a restart loop. The error is constantly 'k mode exception not handled' I looked it up and saw you needed to look at the DMP crash files but found out I can not access them so now wonder how I can see
what the problem is or show you what it is but I do have them available. When it goes into the reset loop I can turn it off by the PSU and take out the cable leave it for 30 mins then it works again for 15 mins....

Please help me I wanna play more games

Many Thanks

 

K Mode Exception Not Handled

The blue screen of death with a KMode Exception Not Handled is making my PC, using Windows 10, unusable by restarting the computer every 10 minutes or so. I have updated all the drivers, unchecked the fast start box and activated the driver verifier.
Troubleshooting sites say this will notify me which driver is causing the problem, but that hasn't been true for me. Trying to start in safe mode as recommended by Microsoft doesn't work, as the KMode exception shuts down the safe mode boot every time I try.
Does anyone have any advice for me? Thanks.

 

After installing latest updates, receives BSOD and says "mode exception not handled"

Hello Scott,

I understand the inconvenience caused to after the Windows 10 update, we will help you with this issue.

Share this information to assist you better.

• Which update caused this issue? Share the KB number.
• Are you able to boot into the desktop?

Mode Exception Not Handled error in Windows mostly arises due to incompatible or old
graphics card drivers. System Thread Exception Not Handled error is often displayed along with the Blue Screen of Death (BSOD).

After the Blue Screen of Death is displayed with System Thread Mode Exception Not Handled error, even if the computer is powered off and then powered back on, it keeps getting restarted after every few seconds.

Step 1: I suggest you to install Windows 10 using the media creation tool:

Step 2: After installing Windows 10, perform an Automatic Repair.

Perform the Automatic repair:

• 
  When your computer starts, wait for the manufacturer logo to check the option for boot menu, it will usually be
  F12.
  
• 
  The boot menu key might differ with each manufacturer. If you are unable to find the boot menu key, you may refer the user manual.
  
• 
  Restart the computer, when the manufacturer's logo is displayed, keep pressing the
  Boot menu option key to enter the boot menu and change the boot option to
  CD\DVD ROM.
  
• 
  After you boot your computer using Windows 8 DVD, a black screen appears with gray text "Press any key to boot from CD or DVD". Press any key.
  
• 
  Select the correct time and
  Keyboard type.
