Driver Easy  fixes the ntoskrnl.exe blue screen error in Windows 7.

If you’re on Windows 7, and you’re seeing this horrifying blue screen telling you that your problem seems to be caused by ntoskrnl.exe, no panic, many Windows 7 users are reporting it, and the best of all, it’s possible to fix. 

3 fixes for ‘ntoskrnl.exe’

Here are 3 solutions for you to try. You may not have to try them all; just work your way down the top and find the one works for you. 

  1. Update device drivers
  2. Reset overclocking settings
  3. Perform a memtest 
You’ll need to be logged into Windows on the problem computer to try any of these solutions. If you can’t log into Windows, power on and off your PC 3 times to perform a hard reboot and restart it in Safe Mode, then try these solutions.

What is ntoskrnl.exe? 

Ntoskrnl.exe is the kernel of the operating system. Without it, Windows just won’t work. If this file is at fault, your computer is very likely to have frequent blue screen of deaths and have more problems other than BSOD. 

1: Update device drivers 

Outdated or faulty drivers is one of the reasons for this blue screen of death error. So whenever you run into a blue screen of death error, one of the first things you do is to verify that all your devices have the right driver, and update those that don’t. 

There are two ways you can get the right drivers for your video card and monitor: manually or automatically.

Manual driver update – You can update your device drivers manually by going to the manufacturer’s website for your hardware devices, and searching for the most recent correct driver for each. Be sure to choose only drivers that are compatible with your variant of Windows 10. 

Automatic driver update – If you don’t have the time, patience or computer skills to update your device drivers manually, you can, instead, do it automatically with Driver Easy. Driver Easy will automatically recognize your system and find the correct drivers for your hardware pieces, and your variant of Windows 10, and it will download and install them correctly

 

1) Download and install Driver Easy.

2) Run Driver Easy and click the Scan Now button. Driver Easy will then scan your computer and detect any problem drivers. 

3) Click the Update button next to all flagged devices to automatically download and install the correct version of their drivers (you can do this with the FREE version).

Or click Update All to automatically download and install the correct version of all the drivers that are missing or out of date on your system. (This requires the Pro version which comes with full support and a 30-day money back guarantee. You’ll be prompted to upgrade when you click Update All). 

2: Reset overclocking settings

One of the reasons for this blue screen of death error is overclocking drivers. If you have a trusted software to help you change the overclock in BIOS, use it. 

If not, follow the instructions below to help you clear the CMOS from within the BIOS menu and reset your BIOS settings back to their factory default state. 

Note: The following instructions are for Windows 7. The procedure is different if you’re ob Windows 8, 8.1 or 10 operating system. 

1) Press and hold the power button for about 10 seconds, or until your system completely shut down. 

2) Power on the system. As soon as the first logo screen appears, immediately press F1F2, F10, ESC or Delete for desktops to enter the BIOS.

NOTE: Sometimes you might need to press the combinations such as CTRL+ ALT+ ESC or CTRL+ALT+DEL if you are using a rather old machine. The keys to press differ from computers of different manufacturers and different models. You might need to choose the correct key to press according to what you see on the notification. 

3) Use the arrow key to go to Exit and then move down to Load Setup Defaults. (Your computer might be different, but you should be able to see the option Load Setup Default.) 



4) Then press the Enter key. You might be able to see notification like this. Use the arrow key to select Yes and then press Enter again.

5) Exit Saving Changes should be highlighted now. Press Enter and then press Enter again to save configuration change. 

You computer will restart. 

Again, the information showing on your computer may be different from mine and you should do the settings accordingly. If you’re not sure how you could perform certain moves, please go to the official support webpage of the manufacturer of your computer and ask for help. 

3: Perform a memtest

The ntoskrnl. exe BSOD is usually related to memory, possibly caused by a faulty driver. It’s suggested that you run the following memory test to verify your memory and find out which driver is causing the problem. 

Note: If you’re over-clocking anything, please shut them down first before you run the tests. You will need to reboot your computer to perform the test. During the test, you won’t be able to use your computer. 

1) On your keyboard, clcik the Start button, then type Windows Memory Diagnostic and press Enter

2) Click Restart now and check for problems(recommended). Be sure to save your work first because your computer will start immediately. 

3) Your computer will restart and the Windows Memory Diagnostic Tool screen will appear.  

The test could take some time to finish. You’ll see the test result after you log on. 

If the test result indicates that something is off with your software or hardware, feel free to leave a comment and we’ll see what we can do to help.

    On Mon 12/25/2017 5:34:09 PM your computer crashed
    crash dump file: C:WindowsMinidump122517-9453-01.dmp
    This was probably caused by the following module: ntoskrnl.exe (nt+0x1640E0)
    Bugcheck code: 0x4E (0x2, 0x84EAC3, 0x8BEFFF, 0x1)
    Error: PFN_LIST_CORRUPT
    file path: C:Windowssystem32ntoskrnl.exe
    product: Microsoft® Windows® Operating System
    company: Microsoft Corporation
    description: NT Kernel & System
    Bug check description: This indicates that the page frame number (PFN) list is corrupted.
    This appears to be a typical software driver bug and is not likely to be caused by a hardware problem. This might be a case of memory corruption. More often memory corruption happens because of software errors in buggy drivers, not because of faulty RAM modules.
    The crash took place in the Windows kernel. Possibly this problem is caused by another driver that cannot be identified at this time.

        • Sophie.Luo

          Hi Candi,
          Thanks for your reply.

          These two posts will show you how to download and install device drivers with Driver Easy.
          Basically, Driver Easy downloads the device drivers you need one by one, and then you need to install them one by one by yourself via Device Manager.

          Actually, you can install them very easily through the control panel. I installed all my drivers through there. You just didn’t research HOW to install the drivers at all.
