Fix 1. Update Drivers or Reinstall Them

Device drivers are special programs that can make computer communicate with devices. They are equivalent to the hardware interfaces. The operating system can only control the work of the hardware devices through these interfaces.

Usually, if the drivers are not installed correctly, the computer can't work well. And ntoskrnl.exe BSOD may also occur because the drivers are out of date. Then you can update drivers or reinstall them to solve ntoskrnl.exe BSOD Windows 10.

Here are tutorials for driver update and reinstallation.

Situation one: The computer can boot into Windows normally.

Step 1: Open Device Manager.

  • Press "Windows + X" keys.
  • Select Device Manager in the pop-up menu.

Step 2: Update all device drivers to make sure that they are all up to date.

  • Expand directories and right click drivers to select Update driver one by one.
  • Select Search automatically for updated driver software in the pop-up window.
Tip: If Windows can't find a new driver, you can find a driver on the device manufacturer's website and follow its instruction to install it. If so, you can uninstall the device driver first, and reinstall the good one later.

update all hardware drivers

Situation two: The computer can't boot into Windows normally, but it can boot into WinRE.

Step 1: Boot into WinRE.

  • Boot into WinRE automatically when the computer detects: two consecutive failed attempts to start Windows, two consecutive unexpected shutdowns that occur within two minutes of boot completion, a Secure Boot error (except for issues related to Bootmgr.efi), or a BitLocker error on touch-only devices.
  • Surely, you can also use Windows 10 install media to enter WinRE when Windows 10 fails to boot automatically.

Step 2: Boot into Safe Mode.

  • Navigate to Troubleshoot > Advanced options after you enter WinRE.
  • Click Startup Settings and wait for a while.
  • Press F5 key to choose Enable Safe Mode with Networking option, thus booting into Safe Mode.

choose Enable Safe Mode option

Step 3: Follow the tutorial in situation one to update or reinstall device drivers.

Fix 2. Diagnose Memory

Memory is one of the most important parts of a computer. It is a bridge to communicate with the CPU. All programs in the computer run in memory, so the performance of the memory has a huge impact on the computer. And the operation of the memory also determines whether the computer operation is stable.

So, ntoskrnl.exe BSOD Windows 10 may be also caused by memory problem. You can diagnose memory problem by the following tutorials.

Situation one: The computer can boot into Windows 10 normally.

Step 1: Perform memory diagnosis.

  • Press "Windows + R" keys and type "mdsched.exe" in to run box.
  • Select "Restart now and check for problems" after the Windows Memory Diagnostic program pops up.
  • Wait until the computer finish memory diagnosis. This process will usually take a few minutes.

Step 2: Open Event Viewer and find the current logs.

  • Type "eventvwr" in run window after the computer reboots automatically.
  • Navigate to Windows Logs > System.
  • Click "Filter Current Log" in the right box to open its window.

check current log of memory test

Step 3: Find the result of memory diagnosis.

  • Select "MemoryDiagnostics-Results" in the drop-down menu of event sources to display all result logs of memory test.
  • Click OK.

Check memorydiagnostics-results to display all result logs of memory test

Step 4: Double click the latest result log to see the detailed information.

Situation two: The computer can't boot into Windows normally, but it can boot into WinRE.

Step 1: Boot into Safe Mode.

Step2: Follow the tutorial in situation one to perform memory diagnosis.

If the result indicates that there are some problems with the RAM, you could check RAM in another normal running computer. If it is the RAM that has problem, you may have to replace the RAM stickers. 

Besides, if the computer is installed with two memory banks with different size and frequency, ntoskrnl.exe BSOD may also happen. You can remove one of them or insert two memory banks with same type to solve this problem.

Fix 3. Disable Overclocking

Sometimes, ntoskrnl.exe crash may be caused by overclocking, which is often related to memory frequency. Memory frequency indicates the speed of the memory, which represents the highest operating frequency that the memory can reach. The current mainstream memory frequency is DDR, DDR2, DDR3, and DDR4.

However, the memory frequency usually stays at a relatively low value. And some senior computer users can utilize overclocking to break through the limitation.

Overclocking can increase the clock speed of an electronic accessory and make it to work at a speed higher than the factory set speed, thereby improving the performance, but this may cause the stability of the accessory to decrease, hence resulting in ntoskrnl.exe crash.
