Repair SYSTEM_SERVICE_EXCEPTION ks.sys BSOD Error

SYSTEM_SERVICE_EXCEPTION (KS.SYS) is a Windows kernel CSA library file that is directly associated with the camcorder. This type of error is especially common on laptops with webcams and HP embedded systems.

SYSTEM_SERVICE_EXCEPTION (KS.SYS) was created a long time ago, but not fully resolved yet. Although there are not many users who have this problem, we have received several reports. This indicates that this may become more frequent due to changes in the Windows system and periodic updates.

The vast majority of BSOD errors occurring these days are related to Windows 10 updates, but the SYSTEM_SERVICE_EXCEPTION (KS.SYS) error is not. This usually happens immediately after updating Skype (especially version 6.14). For some reason, the update introduces incompatibility between the system and the camcorder drivers. Fortunately, this error is easy to fix by following the instructions below.

Uninstall HP Webcam drivers and let your system install generic drivers

The second cause of this issue could be HP webcam drivers that conflict with your system. To fix this problem, you can remove them. Windows then installs generic drivers for your webcam. Thus, you may lose some of the advanced functions of your webcam. However, this is a rather minor sacrifice for good use of your computer.

To uninstall HP drivers, you need to open Device Manager by clicking Start, typing Device Manager and pressing Enter. In the list of devices, find and expand Imaging Devices. Inside you will find device drivers from HP. Right-click and select Delete from the drop-down menu. Follow the instructions in the wizard and your drivers will be removed.

When you’re done, restart your device. Since the driver for the webcam is no longer installed manually, Windows activates the generic driver. It won’t cause conflicts and BSODs, and you can still use your computer.

Although this error affects a very small number of users, it can be a big problem for those who use their computer for important work, as it very often causes your system to crash. However, follow the above methods to resolve the issue and continue using your device.

Install reliable software and scan the system.

System errors such as BSOD SYSTEM_SERVICE_EXCEPTION (KS.SYS) very often indicate the need to optimize your system. There can be problems with saving, starting, caching, caching, etc. So the first thing you should try is to install and run a professional optimizer.

Go back to the old version of Skype

Since this issue is often caused by a fake Skype update, it makes sense to go back to the old version you were using without any problems.

You must first uninstall the version you are currently using. The best way to do this is to open Add or Remove Programs from Control Panel. Click Start, go to the Control Panel and open the result. Set the view in the upper right corner to large or small icons and open Programs or Add or Remove Programs and Features, depending on your version of Windows. Find Skype in the list of programs, click on it, and then click Uninstall. Follow the instructions in the wizard to uninstall Skype. Finally, reboot your device to remove any leftover files.

Turn off / Disable your webcam

Sometimes hardware such as a webcam, even built into your monitor, can cause the SYSTEM_SERVICE_EXCEPTION error. If you get the SYSTEM_SERVICE_EXCEPTION (ks.sys) error, you can disable your webcam by following the instructions below:

  • Open Device Manager. Press Windows + X and select Device Manager from the list.
  • You should now find your webcam in Device Manager, right click and select Disable from the list.

We must mention that other hardware may be causing this problem. Therefore, you may need to take a little look before determining which device is causing this error.
