Files that have a .sys extension are very important for Windows and our computer, since in fact they are responsible for making communication between them occur normally. A failure in any of these can cause problems in our equipment or one of these blue screens. If unfortunately you suffer from one, and you see that win32kfull.sys appears on the screen, try the solutions that we give you below.
Use the BSOD troubleshooter
As we say, blue screens are not too frequent, but even so, it is a problem that can become recurrent depending on which equipment. This particular error may be related in one way or another to the computer’s RAM memory, and although there are some things you can do more “manually”, the first and most comfortable thing is to go to to the BSOD solver offered by Windows itself. This process is automatic, and it will be the operating system itself that looks for where the error may be in order to solve it.
- Press the shortcut Windows + I or type in the search engine Settings
- In the window that appears, go to Update and security
- Click on Troubleshoot, and on the right side of the screen, Additional troubleshooters
- In the next window, we select the Blue Screen or BSOD option
If the solver detects any type of problem related to this error, it will offer us recommendations to solve. In case this happens, we will have to apply these recommended corrections, and with this the problem of the blue screen should be solved.
Install optional updates
Sometimes these types of errors usually begin to appear after installing some kind of Windows update. In these cases, obviously the problem is not in our equipment, but rather it is due to some type of problem with the operating system. Microsoft tends to act very quickly in this type of situation, and releases optional updates specifically for users experiencing these types of problems. To access them, you just have to do the following:
- We access the Windows Settings menu again
- Once inside, select Windows Update
- Click on the blue button See all optional updates
- If it does not appear, it will be because you do not have your system fully updated.
- Select all of them that haya, and install them
- restart the computer
- The problem should have been solved
Repair system files
Another of the most common reasons for this error is in corrupted system files. As we have said a little above, these types of files are key to the proper functioning of our equipment, since they contain very important information. It may happen that the information in one of these files gets out of order or is lost, making the file incomplete. If this happens, it is almost certain that we will suffer from blue screens until we solve this corrupt file, something that usually happens due to system failures, power outages or even some malware.
Windows has its own system to find these files and replace them with others that are correct. To do this, we will have to access the Command Prompt or CMD, although this time we will have to do it as administrator. To do this we will use the Windows search window, we will write CMD and in the result we will press the right button choosing “Run as administrator”. Here we will have to use the command “sfc /scannow”.
Update the drivers
Another very common reason that also causes this specific error is due to the drivers or controllers of our equipment. It may happen that some of the equipment are very obsolete, or even others that are not compatible with our hardware. This one in particular is usually related to display or network driversalthough it does not have to be this way in 100% of the cases.
To check the status of your drivers, do the following:
- In the Windows search engine, type Device administrator. She presses on him.
- In the window that appears are all the drivers of our equipment
- Find if there is one a yellow exclamation mark
- If so, right-click and select Uninstall device
- Once uninstalled, restart your computer.
If you access this screen, and you do not find any device with this yellow symbol, you can try to manually update the network drivers, even if they appear on the screen without said symbol. To do this, simply select them, click on them with the right mouse button and choose the option to update driver.
Check the RAM of your computer
If none of the above tools have worked for you, it may be due to an error in your computer’s RAM. Windows also has a tool that allows us to check the status of our memory, and for this we only have to do the following:
- In Windows Finder, type Windows Memory Diagnostics. Click on it
- In the window that appears, click Reboot now and check for problems
- Once this is done, we will have to press F1 to open the options, and in the next window in Extended
- Then press F10 to apply the changes
In this way, what we are doing is doing a more thorough test on our RAM memory, something that will take a few minutes. Once the process is finished, it should appear on the screen if there is an error with it, or if, on the contrary, everything is perfectly fine. To exit this screen, you just have to press the ESC button on the keyboard.
One of these tools that we have given you should solve the problem of win32kfull.sys. If, unfortunately, you have tried each and every one of them, and, even so, you continue to suffer from this annoying blue screen, you only have contact Microsoft support to tell them about your problem.
