Anatomy of the crash

The crash is something that bothers the operator. The performance when the crash is mostly "blue screen", the system can not be started, the screen "freeze", no response, the mouse, keyboard can not be input, the software runs abnormally interrupted. Although there are many reasons for the crash, but the change is not separated from the situation, the reason can never be separated from both hardware and software.

Deadlock caused by hardware

[Poor heat dissipation]

The display, power supply and CPU generate a lot of heat during operation, so it is very important to maintain good ventilation. If the monitor overheats, it will cause color, image distortion or even shorten the life of the monitor. Too long working hours can also cause the computer or computer to freeze due to poor heat dissipation from the power supply or display. The heat dissipation of the CPU is an important issue related to the stability of the computer operation, and it is also the "hardest disaster area" in which the heat failure occurs.

[Improperly moved]

A large vibration during the movement of the computer often causes the internal components of the machine to loosen, resulting in poor contact and causing the computer to freeze, so avoid severe vibration when moving the computer. .

[Dust killer]

Too much dust in the machine can also cause a crash. If the floppy drive head or the optical drive laser head is contaminated with too much dust, it will cause reading and writing errors, which will cause the computer to crash.

[Device mismatch]

If the main frequency of the motherboard and the CPU frequency do not match, the old motherboard will set the FSB too high when overclocking, and may not guarantee the stability of the operation. Cause frequent crashes.

[Software and hardware are not compatible]

Three-dimensional software and some special software may not be able to start or even install properly on some microcomputers. There may be problems with software and hardware compatibility.

[Memory Bar Fault]

Mainly due to loose memory, virtual solder or memory chip itself. The memory module contact fault should be eliminated according to the specific situation. If there is a problem with the quality of the memory module, the memory needs to be replaced to solve the problem.

[Hard Disk Failure]

Mainly due to aging of the hard disk or bad sectors and bad sectors due to improper use. This makes it easy for the machine to crash when it is running. Special tool software can be used for troubleshooting. If the damage is serious, the hard disk can only be replaced. In addition, for motherboards that do not support UDMA 66/100, you should pay attention to the setting of the hard disk operation mode in CMOS.

[CPU overclocking]

Overclocking increases the operating frequency of the CPU and may also make its performance unstable. The reason is that the speed of CPU accessing data in memory is faster than the speed of data exchange between memory and hard disk. Overclocking makes this contradiction more prominent, which aggravates the situation where the required data cannot be found in memory or virtual memory. This will result in "Exception Error". The solution is of course simpler, that is, let the CPU return to the normal frequency.

[Hardware Resource Conflict]

An error occurred due to a conflict between the settings of the sound card or the display card. In addition, the interruption of other devices, DMA or port conflicts, may cause a few drivers to generate an exception, resulting in a crash. The solution is to start with "Safe Mode" and make appropriate adjustments in the "Control Panel" & rdquo; → & ldquo; System & rdquo; & Rar; & ldquo; Equipment Management & rdquo; For situations where an exception error is generated in the driver, the registry can be modified. Select “Run”, type “REGEDIT”, enter the Registry Editor, and find and delete all the “primary keys” associated with the driver prefix string through the “Find” function under the menu. Key value & rdquo;, restart.

[Insufficient memory capacity]

The larger the memory capacity, the better, it should be no less than 0.5~1% of the hard disk capacity. If there is such a problem, it should be replaced with the largest possible capacity. RAM.

[Inferior Parts]

A small number of unscrupulous traders use poor quality boards, memory, and even sell counterfeit motherboards and Remark CPUs and memory when assembling compatible machines to customers. Such a machine is very unstable at runtime, and it is inevitable that a crash will occur. Therefore, users should be vigilant when purchasing, and can use some newer tools to test the computer, continuous test (such as 72 hours), and strive for the longest warranty time.
