Your PC ran into a problem ... system thread exeption not handled (athwb.sys)

Hello Harold,

Thank you for the update on the issue.

If issue still persists, I would suggest you to manually check if these keys are struck or if anything stuck in between the keys which could prevent the key from functioning properly. If nothing was found, I would suggest you to open the onscreen keyboard and check if these keys work. If these work in the onscreen keyboard, then the issue might be caused due to driver or a faulty hardware.

You can refer to this article to open the on screen keyboard:

If these work in the onscreen keyboard, then the issue might be caused due to driver or a faulty hardware. In this case, I would suggest you to try the following steps and check if it helps.

Method 1: Try Hardware and devices troubleshooter

d) Run the ‘**Hardware and devices ‘**troubleshooter.

Method 2:

Un-install and re-install keyboard drivers from the manufacturer’s website and see if that helps:

Step 1: un-install the drivers:

Follow these steps:

a. Press “Windows Key + W” from the keyboard.

b. Type “device Manager” without quotes in the search box and hit enter.

c. Right click on the keyboard drivers and select “Uninstall”.

d. Restart the computer once it is uninstalled.

Note: Before uninstalling the driver, please make sure that you have downloaded the latest driver for the keyboard device from the manufacturer website.

Hello Ice Chayanit,

Thank you for posting your query on Microsoft Community Forum.

I would appreciate if you can provide us the following information to help us understand the issue in a better way.

1. Do you remember the Windows Update which has caused this issue?
2. Are all the device drivers updated?

System Thread Exception Not Handled error in Windows 8 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 Exception Not Handled error, even if the computer is powered off and then powered back on, it keeps getting restarted after every few seconds.

In order to fix this issue, the computer must be restarted in safe mode, and the problematic graphics driver must be uninstalled. Once this is done, the latest driver of the installed graphics card must be downloaded from the vendor’s official site, and must be installed in order to make the Windows 8 system work.

In order to Enter Safe Mode and Uninstall Graphics Card Driver you can follow the below mentioned steps.

In order to enter safe mode, the legacy advanced boot screen must be enabled in Windows 8. Once the advanced boot screen is enabled, the installed graphics card driver can be uninstalled by going to the Device Manager after booting the computer in safe mode.
