Why does the computer crash?

Computer "blue screen", unable to start the system, the screen "freeze" no response, the mouse, keyboard can not be entered, the software operation abnormal interruption, etc.-this is the performance of the crash. Believe that a lot of friends in the process of using the computer has more or less encountered a computer crash, the computer crash is really a headache, what is the cause of it? Although there are many reasons for the crash, but same, the reason is never out of hardware and software two aspects.

　Panic caused by a hardware cause

"Bad Heat"

Monitors, power supplies, and CPUs are extremely calorific at work, so it is important to maintain a good ventilation condition, and if the display is overheating, it will result in color, image distortion, and even a shortened display life. Too long working hours can also cause power or monitor heat dissipation caused by computer crashes. The cooling of the CPU is related to the stability of the computer operation is an important problem, but also the heat failure occurred in the "hardest hit."

　"Improper movement"

In the process of computer movement by a large vibration will often make the machine internal devices loose, resulting in poor contact, causing computer crashes, so mobile computers should avoid violent vibration.

　"Dust killer."

Too much dust in the machine can cause a crash. such as floppy disk head or optical drive laser head contaminated with too much dust, will lead to read and write errors, serious will cause computer crashes.

"Device Mismatch"

such as motherboard frequency and CPU frequency mismatch, the old motherboard overclocking will FSB set too high, may not guarantee the stability of the operation, resulting in frequent panic.

"Hardware and software is incompatible"

Three-dimensional software and some special software, may be on some computers can not start or even install, which may have hardware and software compatibility problems.

　　"Memory Stripe Failure"

Mainly is the memory strip loose, the virtual welding or the memory chip itself quality is caused. should be in accordance with the circumstances of the memory strip contact failure, if there is a problem with the quality of memory, you need to replace the memory to solve the problem.

　"Hard Drive Failure"

Mainly hard disk aging or due to improper use caused bad, bad sector. This makes it easy to panic when the machine is running. You can use special tool software for troubleshooting, such as serious damage can only replace the hard drive. In addition, for motherboards that do not support UDMA 66/100, you should pay attention to the setting of the operating mode of the CMOS hard disk.

　"CPU overclocking"

Overclocking increases the CPU's working frequency, and may also make its performance unstable. The reason, the CPU in memory access to data faster than the speed of memory and hard disk exchange data, overclocking makes this contradiction more prominent, exacerbated in memory or virtual memory can not find the required data, this will appear "abnormal error." Of course, the solution is also simpler, is to let the CPU back to the normal frequency.

　　"Hardware resource conflict"

is due to a conflict in the sound card or display card settings, causing an exception error. In addition, interruptions of other devices, DMA, or port conflicts may cause a few drivers to be abnormal and panic. The solution is to start in "Safe mode" and make appropriate adjustments in "control Panel" → "System" → "Equipment management". You can modify the registry for situations where an unexpected error occurs in the driver. Select "Run", type "REGEDIT", enter Registry Editor, and, through the "Find" function under the menu, locate and remove all "primary keys" and "key values" associated with the driver prefix string and reboot.

　"Insufficient memory capacity"

The larger the memory capacity, the better, should not be less than the hard disk capacity of the 0.5~1%, such as the problem, it should be replaced as large as possible memory.

　　"Inferior Parts"

A handful of unscrupulous businessmen in the assembly of compatible machines to customers, the use of poor quality of the board, memory, and some even sell fake motherboards and remark of the CPU, memory, such a machine in operation is very unstable, the crash is inevitable. Therefore, users should be vigilant when purchasing, and can use some newer tools software testing computer, long time continuous test machine (such as 72 hours), as well as to strive for the long warranty time.
