Kernel Security Check Failure Error on Windows 10 [Solved]

Sophie Luo, in Blue Screen Error

If you’re seeing the blue screen of death error Kernel Security Check Error, and you have no idea what to do next, you’re not alone. Many Windows users are reporting this problem as well. But no worries, it’s possible to fix. 

Here are 4 fixes for you to try. You may not have to try them all; just work your way down until you find the one works for you. 

Method 1: Undo recent changes
Method 2: Update available drivers
Method 3: Run Memory Diagnostic tool
Method 4: Scan hard disk for error


IMPORTANT: 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. 

1. Undo recent changes 

One of the causes of this blue screen error could be recent changes you’ve made to your system. If you’ve added new hardware or software to your system recently, remove them to see if the problem is fixed. 

2. Update available drivers

This blue screen of death error is very likely to be caused by incompatible drivers. You should verify that all your devices have the right driver, and update those that don’t.

If you don’t have the time, patience or computer skills to update your drivers manually, you can do it automatically with Driver Easy

Driver Easy will automatically recognize your system and find the correct drivers for it. You don’t need to know exactly what system your computer is running, you don’t need to risk downloading and installing the wrong driver, and you don’t need to worry about making a mistake when installing. 

You can update your drivers automatically with either the FREE or the Pro version of Driver Easy. But with the Pro version it takes just 2 clicks (and you get full support and a 30-day money back guarantee): 

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Or click Update All to automatically download and install the correct version of all the drivers that are missing or out of date on your system (this requires the Pro version – you’ll be prompted to upgrade when you click Update All). 

3. Run Memory Diagnostic tool

If the above methods fail to help you solve the problem, you should check if your RAM is at fault. You can check the status of RAM by: 

1) On your keyboard, press the Windows logo key and R at the same time to invoke a Run command. Type mdsched.exe in the run box and press Enter

2) You could choose Restart now and check for problems(recommended) to check the status of your memory card right now, or choose Check for problems the next time I start my computer if you are too occupied now. 

3) You will be seeing this page showing the progress of the check and number of passes it will run on memory.

If you don’t see any error here, it’s likely that your memory card is not causing any issues. If error is detected, it is suggested that you exchange the current memory card for a new one.

4. Scan Hard Disk for Error 

Another cause of this blue screen error is faulty hard drive. You should check if you need to get your hard drive replaced: 

IMPORTANT: Please make sure you have closed all open programs and files before your disk check.

1) On your keyboard, press the Windows logo key and E at the same time. Click This PC

2) Right-click the hard drive that you want to check and click Properties.

3) Go to the Tools tab and click Check option.

4) If your hard disk drive is problem free, you will see the notification like this:

If you don’t see this notification, please consider buying a new hard disk drive to get this problem solved.

    That’s probably the most useless article I’ve ever seen! Why would you add (Solved) statement to it when this won’t solve anything? Nothing here relates to my Kernel Security Check BSOD!
    You guys really need to learn some thinks or two about your own job.
    It’s just generic “you have some unspecified BSOD error so you should update all your drivers” ordeal. Tsk, tsk… its just sad.

    Microsoft is always “Checking for solutions” of collecting some data, but they never tell you what they collected and where it is stored. So in the very first screen shot comes the statement: We’re just collecting some error info and then we will restart your computer.” You’d think if they were collecting data, it would tell where the problem was. You’d think.
