Solved: Kmode Exception Not Handled Error

Why there is Kmode exception not handled error?

The "KMODE_EXCEPTION_NOT_HANDLED" error is a Blue Screen of Death (BSOD) that typically occurs on Windows when there's an issue with system-level software or hardware. It indicates that the kernel-mode process (which runs critical system functions) encountered an error that it couldn't handle. Here's why it can happen:

1. Driver issues: A common cause for this error is corrupt or incompatible drivers. Outdated or improperly installed drivers, particularly for hardware like graphics cards, sound cards, or network adapters, can conflict with the Windows kernel and cause this error.

2. Hardware problems: Faulty hardware, especially RAM or hard drives, can lead to this error. Issues like bad memory sectors, failing RAM, or problems with your hard disk (e.g., SSD or HDD) can corrupt the kernel’s ability to function properly.

3. Corrupt system files: If critical Windows files become corrupted or missing, it can trigger this error. This often happens after a Windows update, when system files may fail to update correctly.

4. Faulty or overloaded system resources: If your system is overloaded or has too many processes running, it might struggle to allocate resources properly, causing a kernel mode exception.

5. Windows updates: Sometimes, a Windows update can trigger this error if there’s a problem with the new update. This might be due to a conflict with existing hardware or software.

Outdated or corrupted drivers can often trigger the Kmode Exception Not Handled error. It’s essential to make sure all your drivers, especially graphics, network, and storage drivers, are up to date.

Step 1. Press Windows + X and select Device Manager from the list.

Step 2. Look for any devices with a yellow triangle symbol (indicating issues) in the Device Manager.

Step 3. Right-click on the device with the issue and select Update driver.
