The common causes and solutions to the "page fault in nonpaged area" blue screen error are as follows: 1. Driver or software conflicts are conflicted. It is recommended to enter safe mode to uninstall recently installed drivers or software, especially unofficial drivers; 2. Memory problems, use Windows memory diagnostic tools or MemTest86 to detect and try to re-plug and unplug the memory module; 3. System files are corrupted, run sfc /scannow and DISM commands to repair system files; 4. Others may include updating the BIOS, checking for bad hard disk channels, turning off overclocking settings, etc. In most cases, the above steps can be used to locate and solve the problem.

When encountering the blue screen error "page fault in nonpaged area", many people's first reaction is that the system is broken or the hardware is wrong. In fact, although this error seems scary, it does not necessarily mean that the computer will completely collapse. In most cases, it can be investigated and solved.

What is "page fault in nonpaged area"?

Simply put, this error usually occurs when Windows tries to access a certain area in memory, but finds that the area is inaccessible, and this area is not allowed to be paging onto the hard disk (that is, the so-called nonpaged area). Common reasons include:

• Driver incompatible or corrupt
• There is a problem with the memory (RAM)
• System file corrupt
• Software conflicts, especially antivirus software or virtual machine-related tools

After this blue screen appears, the system will generally restart automatically, so the first thing to do is not panic, but record the error message and see if there are any other prompts, such as which module caused an exception (usually there will be codes like STOP: 0x00000050 , as well as module names, such as ntoskrnl.exe or third-party drivers).

Check for recently installed drivers or software

In many cases, this problem is caused by newly installed drivers or software, especially graphics card drivers, antivirus software, virtual machine tools, etc. that have a greater impact on the underlying system.

Recommended operations:

• Enter safe mode and uninstall the recently installed driver or software
• Pay special attention to drivers that are not officially signed by Microsoft, such as those provided by some peripheral manufacturers.
• If you have just updated the graphics card driver, you can try to completely clear it with DDU (Display Driver Uninstaller) and reinstall the stable version

If you are not sure which driver has a problem, you can view the system log in the "Event Viewer" and find the error record before the blue screen occurs.

Check memory problems

Because this error directly involves memory access, the problem of the memory stick itself cannot be ignored. Sometimes even if the memory is only a little bit of poor contact, it can lead to intermittent blue screens.

Suggested Methods:

• Use Windows' built-in memory diagnostic tool (Windows Memory Diagnostic) and enter it in the search bar to run it
• Or use MemTest86 for more comprehensive testing (need to create a boot disk)
• If there are two pieces of memory, you can try plugging and unplugging one by one to see if there is any problem with one piece of memory.

If you find that there is indeed a problem with the memory, replacing or replugging the memory stick can often solve the problem.

What to do if the system files are corrupted?

If the system files are deleted or corrupted by mistake, it may also lead to such low-level errors. At this time, you can use the system's own repair command to check and repair.

Recommended commands:

 sfc /scannow

If this command does not find any problem, you can run further:

 DISM /Online /Cleanup-Image /RestoreHealth

These two commands can handle most system files corruption. It is recommended to restart once after execution to see if there is still a blue screen.

Other things you may need to pay attention to

In addition to the above mentioned situations, there are some details that are easily overlooked:

• Update BIOS to the latest version, some motherboards have compatibility issues with the new version of Windows
• Check whether there are bad channels in the hard disk, use chkdsk /f /r command to scan the disk
• Turn off the overclocking setting. If you have overclocked the CPU or memory before, try to restore the default frequency.

These steps may not necessarily be done, but if none of the previous methods solve the problem, you can gradually check these possibilities.

Basically, these common investigation directions. Although this blue screen looks serious, it can be located in specific reasons most of the time. The key is to start with recent changes and eliminate possible factors step by step.
