What is a Bluescreen?

Computer blue screen, also known as Blue Screen of Death (BSOD), is a screen image that is forced to be displayed in order to protect computer data files from being damaged when Microsoft's Windows series operating system cannot recover from a system error.

Error updating graphics card driver

Blue screen failure of the computer after incorrectly installing or updating the graphics card driver is also one of the main reasons. Restart the computer and press F8 to enter safe mode. Remove the graphics card driver cleanly in the control panel of safe mode. Then restart and enter the system normally, reinstall the graphics card driver or change to another version of the graphics card driver. It is strongly recommended to use the driver to install or update the graphics card driver. For some users who do not know much about the computer, this software is the most suitable. One-click detection and installation, according to the user's computer model and configuration, it is recommended to install a computer compatible with the computer. Driver, which effectively prevents user's wrong operation from causing the blue screen failure of the computer due to incorrect installation of the graphics card driver.

Computer overclocking

Overclocking is a major hardware issue causing blue screens. Excessive overclocking, due to overload calculations, results in excessive internal calculations, overheating the CPU, and resulting in system operation errors. If you want to overclock and don't want a blue screen, you only need to do a good job of heat dissipation. Change to a powerful fan and add some heat-dissipating materials such as silicone. In addition, moderate overclocking or simply not overclocking is one of the solutions. For most users, overclocking is generally not performed, so this is generally not practical.

Bad memory module or bad memory

In actual work, the blue screen phenomenon that I encountered the most is the bad contact of the memory module (mainly caused by too much dust inside the computer, which often occurs in old computers) and the blue screen caused by hard disk failure. You can try to open the computer case, pull out the memory module, clean the slot, and clean the memory module with gold fingers, and then install it back. If the problem is not resolved, it is determined that the memory is faulty. Replace the memory module.

Hard drive failure

Problems with the hard disk can also cause a blue screen on the computer, such as bad sectors on the hard disk, and a blue screen phenomenon caused by computer error in reading data, because the hard disk and the memory carry some data access operations, such as the area where the system file is accessed / read Bad sectors can also cause the system to fail to run properly, resulting in a blue screen on the system or computer. First detect the bad sectors on the hard disk. If there are a lot of bad sectors on the hard disk, it is recommended to back up the data and replace the hard disk. If there are fewer bad sectors, it is recommended to back up the data and reformat the partition disk. Friends who know the hard disk of the computer can also isolate the bad disk to the hard disk area. Then reinstall the system.

Incompatible software installed

If the computer has been used normally before, and the blue screen of the computer frequently appears after installing some software, it may be because the software is incompatible, but this situation rarely occurs. After confirming that the computer has been normal before, the blue screen failure often occurs after installing the software. It is recommended to uninstall the software to try. If the problem is not resolved, it may be other reasons.

Computer virus

Some viruses and Trojans infect system files, causing system file errors or exhausting system resources, and may also cause blue screens. It is recommended to restart the computer for anti-virus operation and use the current mainstream anti-virus software to check and kill. If a malicious virus is encountered, it is recommended to restore or reinstall the system.

Computer temperature is too high

The high temperature of the internal hardware of the computer is also a common cause of the blue screen phenomenon of the computer. The high temperature is mainly based on the CPU, graphics card, and hard disk as an important reference. If the blue screen of the computer appears and the internal temperature of the computer is very high, then the blue screen of the computer may be caused by poor heat dissipation. If it is caused by the temperature of the CPU or the graphics card, then turn on the CPU and the graphics card fan. If the temperature of the hard disk is too high, the hard disk may be faulty and need to be replaced.

Once encountering the blue screen, most people will think that Windows is not working, so they are paralyzed. The culprit is Windows, or Windows is not strong enough or stable enough. You know, whenever there is

Part of the code meaning

1.0x0000000A: IRQL_NOT_LESS_OR_EQUAL

Error analysis: It is mainly caused by problem drivers, defective or incompatible hardware and software. From a technical point of view, it indicates that there is a level process request (IRQL) in kernel mode to access memory addresses that it does not have permission to access.

Solution: Please use the solutions 2, 3, 5, 8, and 9 in the solution to try to exclude.

2, 0x00000012: TRAP_CAUSE_UNKNOWN

Error analysis: If you encounter this error message, it is unfortunate, because the result of KeBugCheckEx analysis is that the cause of the error is unknown.

Solution: Since Microsoft can't help you, you have to rely on yourself. Please remember carefully when this error occurred; what you did to the system when it first happened; what operation was in progress when it happened. Use this information to identify possible causes, and then select the appropriate solution to try to eliminate.

3.0x0000001A: MEMORY_MANAGEMENT

Error analysis: This memory management error is often caused by hardware, such as: newly installed hardware, memory problems, etc.

Solution: If it appears during the installation of Windows, it may be because your computer does not meet the minimum memory and disk requirements for installing Windows. Please increase the memory or allocate more disk space.

4.0x0000001E: KMODE_EXCEPTION_NOT_HANDLED

Error analysis: The Windows kernel detected an illegal or unknown process instruction. This stop code is usually caused by a problem with the memory or a similar reason as the previous 0x0000000A.

Solution:

There is a problem with hardware compatibility: Please check the latest hardware compatibility list to see if all hardware is included in the list. Or use the corresponding Windows Upgrade Assistant to check the hardware requirements.

Problematic device driver, system service, or memory conflict and interrupt conflict: If the driver name appears in the blue screen message, try disabling or removing the driver in the installation mode or the recovery console, and disable all newly installed Drivers and software. If the error occurs during system startup, please enter safe mode and rename or delete the file indicated in the blue screen message.

(3) If the error message clearly states that Win32K.sys: is most likely caused by a third-party remote control software, the software service needs to be turned off from the recovery console.

Appears on the first restart after installing Windows: The biggest suspect may be insufficient disk space on the system partition or a problem with BIOS compatibility.

If it occurs when you close certain software: It is very likely that the software has a design flaw, please upgrade or uninstall it.

Device drivers or operations running in kernel mode

The blue screen of death prompt for the Windows operating system has become an iconic screen, indicating a problem with the software. But few people know that the text on this screen comes from the former Microsoft CEO

Blue screen error code 0x0000007F

1, caused by memory failure or overclocking of hardware devices such as CPU, memory, graphics card

Solution: It is recommended to first check whether the hardware devices such as CPU, memory and graphics card have been overclocked. If so, please restore the overclocked devices to the default operating frequency.

If the problem persists, it is recommended that you update your hardware driver. Given that you have problems after networking, we recommend that you pay particular attention to whether your network card driver version is compatible with win8.1.

2.A lot of hardware will cause blue screen

Solution: Key file tips can also help us find the problem, such as Ndu.sys The full name of the file "Windows Network Data Usage Monitoring Drive" is responsible for network aspects;

We can check whether the network card is damaged or the driver is installed correctly, so if there is such a mention, you can Baidu look at the usefulness of the file in the prompt, which can greatly reduce the scope of your troubleshooting. Check the hardware or update the hardware driver before fixing the blue screen failure.
