Bug check 0x1E (KMODE_EXCEPTION_NOT_HANDLED) indicates that a kernel-mode program generated an exception that the error handler did not catch. This is typically caused by a faulty device driver, system service, or sometimes hardware/BIOS issues.
Because the minidump itself is not available in the provided context, only general, supported troubleshooting steps can be given:
- Check for faulty or incompatible drivers
- Open Event Viewer and review System logs around the time of the crash for driver or service errors.
- In Device Manager, look for devices with warnings and update, roll back, or temporarily disable recently added or updated drivers (for example, storage, chipset, or antivirus drivers).
- If a specific driver name appears in any future bug check screen, disable or remove that driver and get an updated version from the hardware vendor.
- Review recent hardware or firmware changes
- If any new hardware was added (including storage devices), confirm it is certified and compatible with the installed Windows 11 version.
- Check the system BIOS/UEFI version on the Dell XPS 8960 and update it from Dell’s support site if a newer stable version is available, as BIOS incompatibilities can cause 0x1E.
- Use Safe Mode if crashes recur during startup
- If future 0x1E errors occur during boot, start Windows in Safe Mode and disable or uninstall problematic drivers or services from Device Manager or Apps & Features.
- Run hardware diagnostics
- Use Dell’s built-in diagnostics (especially memory tests) and any SSD diagnostics provided by Samsung to rule out RAM or storage issues that can surface as kernel exceptions.
- Analyze future dumps if available
- Ensure that small memory dumps are enabled so that future crashes generate minidumps that can be analyzed with debugging tools or by support personnel.
If the issue repeats frequently, focus first on storage, chipset, and antivirus/security drivers, and verify BIOS and firmware are fully up to date.
