Why does my computer always have a blue screen?

The reasons why the computer always has a blue screen are: 1. The graphics card driver is updated incorrectly; 2. The computer is overclocked; 3. The memory module has poor contact or the memory is damaged; 4. The hard disk fails; 5. The installed software is incorrect. Compatible; 6. Virus in the computer; 7. The computer temperature is too high.

Cause of computer blue screen:

Error updating graphics card driver

Incorrect installation or Computer blue screen failure is also one of the main reasons after updating the graphics card driver. Restart the computer and press F8 to enter safe mode. Delete the graphics card driver in the safe mode control panel Add and Delete: Then restart the system normally and reinstall the graphics card driver or change to another version of the graphics card driver. It is strongly recommended to use Driver Life to install or update the graphics card driver. For some users who do not know much about computers, this software is the most suitable. It can detect and install with one click. According to the user's computer model and configuration, it is recommended to install a computer that is compatible with the computer. driver, effectively preventing user errors in installing the graphics card driver and causing computer blue screen failures.

Excessive computer overclocking

Excessive overclocking is a major hardware problem that causes blue screens. Excessive overclocking, due to overloading operations, causes too many internal operations, causing the CPU to overheat, resulting in system operation errors. If you want to overclock but don't want a blue screen to appear, you can only take good heat dissipation measures. It will be much better to change to a powerful fan and add some heat dissipation materials such as silicone. In addition, moderate overclocking or no overclocking at all is also one of the solutions. Most users generally do not perform overclocking operations, so this is generally not practical.

Poor memory stick contact or memory damage

In actual work, the most common computer blue screen phenomenon that the author encounters is poor memory stick contact (mainly caused by too much dust inside the computer. Old computers often (occurrence) and hard disk failure mostly cause computer blue screen. You can try to open the computer case, pull out the memory module, clean the slot and wipe the gold finger of the memory module before putting it back again. If the problem is not solved, it is determined to be a memory failure and you can replace the memory module.

Hard drive failure

Hard drive failure can also cause a blue screen on the computer. For example, if the hard drive has bad sectors and the computer reads data incorrectly, the blue screen phenomenon occurs because the hard drive, like the memory, carries some data. Retrieval operations, such as bad sectors in the area where system files are accessed/read, will also cause the system to fail to run normally, resulting in a blue screen for the system or computer. First, check the bad sectors of the hard disk. If the hard disk has a large number of bad sectors, it is recommended to back up the data and replace the hard disk. If there are relatively few bad sectors, it is recommended to back up the data and reformat the partitioned disk. Friends who know computer hard disks can also isolate the bad sectors on the hard disk. Then reinstall the system.

The installed software is incompatible

If the computer has been used normally before and a computer blue screen frequently appears after installing a certain software, it may be because the software is incompatible, but this situation is generally very common. Happens less. Before confirming, the computer has been working normally, but after installing the software, a computer blue screen failure often occurs. It is recommended to try uninstalling the software. If the problem is not solved, there may be other reasons.

Viruses in the computer

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

Computer temperature is too high

Excessive temperature of the internal hardware of the computer is also a common cause of computer blue screen. Excessive temperature is mainly based on the CPU, graphics card, hard disk, etc. as important references. If a computer blue screen appears and the internal temperature of the computer is very high, it is likely that the computer has a blue screen caused by poor heat dissipation. If it is caused by the temperature of the CPU or graphics card, then turn on the computer and see if the CPU fan and graphics card fan rotate normally. If normal, it is recommended to strengthen the heat dissipation of the host, such as adding Chassis heat dissipation, etc. If the hard disk temperature is too high, the hard disk may be faulty and needs to be replaced.

Once they encounter a blue screen, most people will think that Windows is not working, so they will be paralyzed. The culprit is Windows, or Windows is not powerful or stable enough. You know, whenever a kernel-mode device driver or subsystem triggers an illegal exception, Windows will face this difficult choice. Although Windows eventually chooses to crash, this does not mean that it cannot ignore the exception. Let the device driver or subsystem continue execution.
