What causes a computer to freeze?

There are many reasons, which are divided into software failures and hardware failures, 1. Hardware.

Device mismatch, such as a mismatch between the main frequency of the motherboard and the main frequency of the CPU, and the main frequency of the motherboard is too high or too low, which may cause frequent crashes.

Software and hardware are difficult or incompatible, such as running Photoshop, AutoCAD and other software, AMD K6 CPU is better than the old Celeron CPU.

The board or card is in poor contact, loose, or the slot, graphics card, memory, CPU and other accessories are damaged.

If the voltage is too low or too high, it may be due to a power failure or due to an unstable external power supply.

The disk has bad sectors, bad sectors, or bad clusters, the disk is aging, or is caused by an unstable external power supply.

The CPU is not cooling well or overclocking is too high.

The reading ability of the head or the bald head is insufficient, and the reading ability of the head will be reduced due to poor working environment and other reasons.

Memory module failure or insufficient capacity, such as loose memory module, virtual soldering, or quality problems of the memory chip itself.

Some of the accessories have been damaged, but the plug-and-play technology allows the system to still detect these devices at boot causing a crash.

2. Software.

Virus interference, viruses can make the computer work efficiency drop sharply, causing frequent crashes.

Poor or incompatible software, mismatch between application software version and operating system, are the most common examples of software compatibility.

Misoperation, such as the inability to open or release the program in an illegal format or with parameters.

Improper memory management, such as a very important file under DOS, is directly related to memory usage and allocation.

There are too many or too few buffers, and different models and different software environments have different requirements for their buffers.

If the CMOS parameter is set improperly, the CMOS directly sets the hardware parameters and usage of the entire computer system.

If the disk space is too full, the hard disk should not use more than or 80% of the total capacity at any time.

Software bugs.

Dynamically link library files in subdirectories such as system system. DLL is lost, causing Windows system to be paralyzed.

In addition, the virtual machine group is on the product**, which is super cheap.

The temperature of the CPU is too high! You can use Master Lu to check it out! If there is no poisoning premise, this reason is your reason!!

Change the fan of the CPU. The graphics card should also be changed.

The temperature of the graphics card is too high, your graphics card is low-end, it's best to change to a mid-to-high-end graphics card, listen to what you said about the fan is not a problem, if so, please change a fan immediately, because if the fan is not good, it is not good to have good heat dissipation.

There should be something wrong with the graphics card.

The configuration should be fine, especially when it comes to a game like CF N years ago.

It is normal for the graphics card fan to change in speed and slowness, after all, such a card will never run 100% of the time.

If you are stuck, I guess the power option is energy-saving, or there is too much dust (I guess it is the former) does not mean that your power supply is not good, but where in the system is set up to save energy or what energy-saving and frequency-reducing software is installed.

There are several reasons for the crash:

1--The hardware must be incompatible, such as: insufficient power of the power supply (including the undervoltage and overvoltage of the mains), the connection between the board and the motherboard (clean the electrodes and slots of the gold finger, and install the clamp tightly), and the problems between the drivers. If the BIOS battery voltage is insufficient or the data is messy, it may crash.

2--The conflict between the software and the system, if there is such a problem after you install some new software, you will uninstall the software, or you will return the system.

3--Conflict between software and software, such as: browser, antivirus and other similar software, you install two or more, they will inevitably conflict and fight, one is enough, redundant uninstall, 4--Incompatibility between the driver and the system (driver and hardware): If you update a driver, there is a blue screen of death.

It's better to install your own hardware.

5--Poor heat dissipation is also the main cause of crash or automatic shutdown, it is necessary to clean the dust in the chassis regularly, lubricate the fans regularly, and make them rotate flexibly. Also see if the heatsink is in good contact with the hardware.

6--Virus Trojan is the cause of computer crash: virus Trojan damage to system files [such as loss of important dynamic links (DLLs), or important configuration files (such as etc.), system driver files (such as etc.), etc.], resulting in computer crash.

Antivirus repair it, redo the system if necessary.

Here's how to deal with it.

1--Restore the BIOS to default settings--- disconnect your power supply (plug it), remove the battery from the motherboard, and install it after a minute.

2--Remove your memory, graphics card, sound card and other boards, clean them up, and wipe the gold finger electrodes with an eraser.

3--Clean motherboard dust, CPU cooler, board slots, etc.

4--Install all boards including --- battery, memory, graphics card, sound card, etc.

5--Energizing test.

6 - Works fine.

7 - Redo the system if necessary.

Most importantly--- good luck!

Do you want to beep?? Is it the audio or the motherboard If it is the motherboard, you can refer to: the motherboard alarm of the encyclopedia, which has a detailed answer!

Remember to apply silicone grease to the CPU, and the graphics card is also coated a little bit on the graphics card chip. Helps conduct heat.

Poisoned, reinstall the system.

CPU oxidation.

The contacts on the CPU are in contact with the pins on the motherboard, and the direct consequence of contact oxidation is poor contact, which causes the CPU to not work normally, resulting in a crash. The solution to this is very simple, just remove the CPU and wipe it clean with an eraser.

**Processor, CPU is a very large-scale integrated circuit, is the computing core and control core of a computer, its function is mainly to interpret computer instructions, as well as process data in computer software.
