A Blue Screen of Death (BSOD) issue, “UNEXPECTED KERNEL MODE TRAP” causes Windows to crash or freeze unexpectedly. When a CPU generates a trap or an exception is not caught by the kernel, the aforementioned error occurs.
The aforementioned problem might also be caused by hardware that is either defective or improperly connected.
How to Resolve the “UNEXPECTED KERNEL MODE TRAP” Error?
Restarting your computer is the first step in fixing the aforementioned error. If the problem persists, try the following:
Fix 1. Check Memory
Unexpected Kernal Mode Trap could be the result of corrupted or incompatible RAM. In that case, a memory check is in order. This requires either a regular Windows boot or the ability to boot into Safe Mode. When a computer won’t start normally, what should you do to get into Safe Mode? Follow the instructions below.
Step 1: First, after two unsuccessful attempts to start Windows or installation media, boot into WinRE.
Step 2: The second step is to enter WinRE and then go to Troubleshoot > Advanced options. To enter Safe Mode, hit the F5 key during startup and select the option to Enable Safe Mode with Networking.
The following are the stages for conducting a memory test:
Step 1: Search for “memory diagnostic” in the Windows search bar. To run Windows Memory Diagnostic, simply double-click the appropriate icon.
Step 2: Optionally, check for issues and try restarting.
Step 3: After the restart, the computer will check the RAM for errors. The computer will automatically restart after the diagnosis is complete. The next step is to review the medical examination results.
Step 4: Bring up the Run dialog by pressing the Windows key plus R at the same time. In the Run box, type “eventvwr” and hit Enter.
Step 5: Go to the Windows Logs > System menu. Then, in the right box, select Filter Current Log.
Memory test logs can be viewed in full by selecting MemoryDiagnostics-Results from the Event sources drop-down menu and clicking the OK button in Step 6.
Step 7: Double-click the logs of the results to get both the summary and the specifics. You can attempt these solutions if memory is not the problem. Errors in memory can be corrected using the appropriate procedures.
Fix 2. Troubleshoot Hardware Failures
It’s possible that device incompatibility or hardware failure is to blame for the UNEXPECTED KERNEL MODE TRAP issue. If you have installed any new hardware on the computer, try taking it out to see if the problem still occurs.
If any existing hardware is broken, it must be fixed immediately. In Windows or Safe Mode, you can run the Hardware and Devices troubleshooter to determine which hardware component failed and how to fix it. Follow the instructions below.
Step 1: To begin, select the Start menu from the left sidebar, and then select the Settings icon.
Step 2: Select Troubleshoot under Update & Security.
Step 3: In the lower-right hand corner, select Hardware and Devices. Click the Troubleshoot button then.
Fix 4. Check Drivers
If the problem appears after updating or installing a new device driver, uninstall the driver and try installing the previous version. After Windows or Safe Mode has loaded, you can revert or uninstall it. This is the guide:
Step 1: Open the Start menu by pressing the “Windows + X” keys, and then click “Device Manager” from the menu that appears.
Step 2: After the driver has been installed, expand the appropriate directory and right-click on the driver’s file.
Step 3: Either revert the driver installation or remove it.
Step 4: Click Properties, then directly go to Driver to revert the driver.
Next, select Roll Back Driver and confirm with OK. This means the updated driver can be uninstalled.
Once you have the correct driver downloaded from the manufacturer’s website, you can uninstall the old driver by selecting it from the list and clicking the Uninstall device button. Finally, open the folder containing the newly downloaded driver and run the setup file.
Conclusion
There are a few possible causes for this mistake. Having a RAM module that sporadically generates read/write failures is the most prevalent cause of this problem. If this is the case, you should run a system scan and swap out the problematic RAM chip.
A driver that is either obsolete or corrupt could also be to blame. It is possible that one or more of your device drivers are incorrectly set up, corrupt, or out of current. If you run an older version of Windows, you may get this after updating Windows Update or after performing a system downgrade.
