What should I do if my computer freezes and the screen freezes?

Computer crash is a very common problem. The problem is that the computer freezes and the screen is stuck. The keyboard and mouse cannot be used or moved. The only way is to force restart the computer. It may not take long after the restart. The phenomenon of freezing the screen occurs. Generally speaking, computer crashes are usually caused by problems such as hardware temperature, overclocking, hardware failure, viruses, etc., so you need to check them one by one to solve the problem. So what should I do if my computer freezes and the screen freezes? Let's share the reasons and solutions for computer crashes to see how to solve this computer failure.

Causes and solutions to computer crashes

• Causes of computer crashes 1: Crash caused by excessive hardware temperature

For example, if the temperature of hardware such as CPU, graphics card, hard disk, etc. is too high, it will crash. If you find that your computer frequently crashes or freezes abnormally, you can first use relevant software to check the hardware temperature, such as Master Lu and Aida64 software.

The normal startup temperature of the CPU is 30-50%. For large-scale software or games, the normal temperature will be 60°C-80°C. It is considered too high if it exceeds 80°C. It is necessary to check whether the CPU radiator fan has stopped spinning, whether there is excessive dust and blockage, etc. Regular maintenance, such as cleaning the computer, replacing CPU silicone grease, etc. It may also be that the CPU radiator is too poor to hold down the CPU.

The temperature of the motherboard is generally 30 to 60℃. Excessive temperature of the motherboard is generally caused by too much dust.

The temperature of the hard disk is mainly around 50°C or 60°C, and its operating temperature limit should be less than 70°C. M.2 solid state can add a heat sink.

The normal temperature of the graphics card should be between "30℃-85℃". If it exceeds 85℃, it is too high.

Regarding the hardware temperature being too high, desktops can also be improved by adding a chassis fan, and notebooks can be improved by adding a cooling base.

• Cause of computer crash 2: The virtual memory setting is too small and causes a crash

If the virtual memory setting is too small, it may also cause the system to crash. You will be prompted that the virtual memory is insufficient and you need to reset the virtual memory size. To set virtual memory, take win10 as an example. First, we right-click "This PC", click "Properties", click Advanced System Settings, in the Advanced tab interface of system properties, click "Settings" in the Performance column, and in the Performance Options interface , click "Change" in the virtual memory column, and uncheck "Automatically manage paging file sizes for all drives. The best setting for virtual memory is (virtual memory is 2 times the physical memory). For example, our computer uses 8GB of memory. Click "Custom Size", we set the initial size of virtual memory to 8000M (physical memory size), the maximum value is 16000M (2 times the physical memory), and click the Set button and confirm.

• Cause 3 of computer crashes: Virus Trojans

Virus Trojans damage system files, causing the computer to often crash. It is recommended to use anti-virus software to check and kill.

• Cause of computer crash 4: crash caused by overclocking

Overclocking CPU, graphics card or memory crashes, for example, after the CPU is overclocked, the CPU temperature is too high or the CPU is powered after overclocking Insufficient will also cause the computer to crash. The graphics card will crash due to overclocking the core frequency, the memory frequency will be too much, and the voltage will crash (XMP may not be stable). If you have overclocked a certain piece of hardware, please set the overclocking settings to the default Test the frequency.

• Cause 5 of computer crashes: crashes caused by hard drive failure

When a mechanical hard drive is used for a long time, bad sectors will also appear on the computer. The phenomenon of freezing, including damage to the solid state drive, will also cause a blue screen of death. I had a computer before, and the computer often crashed. I checked all the problems, including full formatting of the solid state drive and reinstalling the system, to no avail. The temperature was normal and the partitions were normal. It is also 4K aligned, and finally the solid state drive is replaced. Regardless of whether the mechanical hard drive or the solid state crashes, if there is a warranty, it is recommended to repair it. If there is no warranty, it is recommended to repurchase and replace it. SATA hard drives do not rule out problems caused by poor contact or damage to the SATA data cable. You can try replacing the SATA data cable.

• Cause 6 of computer crash: crash caused by memory failure

Crash caused by memory failure or incompatibility or poor contact. If the newly added memory crashes or has a blue screen, it may be the fault of the new memory. If there are two or more memory sticks, you can use the elimination method to solve the problem. Only keep one memory stick to test whether it crashes or has a blue screen. If it fails, replace it with another memory stick to test.

• Cause of computer crash 7: Peripheral short circuit causes crash

For example, U disk or keyboard and mouse, If the computer crashes due to a short circuit in the camera, it is recommended to remove all USB devices for testing (installation home). For example, only a USB mouse or a USB keyboard is left. Turn on the computer and test it to eliminate the short-circuiting devices. I once encountered the problem of short circuit between U disk and keyboard. For example, if I encounter the problem of keyboard short circuit, just remove it, including U disk. If I don’t plug it in, there will be no crash problem.

These seven are very common reasons for computer crashes. Of course, system problems or software conflicts are not excluded. It is recommended that if you cannot find the problem with the system or software conflicts, reinstall the operating system. See If the system continues to freeze, you can directly eliminate the problem on the system. If there is no problem on the system, then you need to find the problem on the hardware.
