What do computers fear most?

first, the hard disk

Hard disk is the most afraid of vibration, a large vibration will let the head component hit the disc, scratched the bad things can be, repair are not good repair, the most important thing is your data can not have your--painstaking care yo!

　　Second, the motherboard

The main board is afraid of static and deformation. Static electricity can damage the BIOS chip and data, a variety of MOS transistor-based interface gate circuit, they are bad, all the "user" (inserted on the board or the device above it) can not find each other, because they are connected by the bus, control chipset, control gate circuit to coordinate and implement. The deformation of the Board may make the circuit board break, component desoldering, the line on the board is very dense, broken you can not find at all.

　　Third, CPU

CPU is the heart of the computer, it is most afraid of high temperature and high voltage. High temperature can easily make the internal circuit electronic migration, shorten the life of the CPU, high voltage is more dangerous, it is easy to burn your CPU, overclocking should try not to increase the core voltage to help excess, because it is not worth the candle.

　　Four, memory

Memory compared to the fear of overclocking, once not reached the required frequency, very easy to appear black screen, even heat damage.

　　Five, optical drive

The optical drive is most afraid of dust and vibration. Dust is the laser head of the "killer", vibration will also make bald "play", damaged bald. In addition, poor CD-ROM is also the enemy of the optical drive, it will increase the burden of the bald servo circuit, speed up the wear of the movement, speed up the aging of the laser tube. Believe it or not, the market is now popular DVCD disk is the most dangerous enemy of optical drive, because its light point distance and ordinary optical drive design standard point distance is much smaller, optical drive read it is like myopic people to see the teeny small print as difficult, maybe one day "blind"

　Six, floppy drive

It is most afraid of dust and mechanical impact, dust will plug the head, read and write errors, the impact is easy to make the head assembly translocation, the floppy drive can be trouble, the correction head must use a dedicated instrument, manual correction is not impossible, that requires great patience and meticulous effort.

　　Seven, power supply

Power supply is afraid of repeated boot, shutdown. When powering on, the switching power supply needs to establish a process from the start to the balance, the frequency instability during the start-up process, the impact current is large, it is easy to burn off the switch tube. Most of the switching tubes are burned at the moment of boot.

　Eight, display

The display is the interface that communicates with the person, is also the power consumption of the whole computer system, is the most easily damaged part. Its most feared is the impact, high temperature, high pressure, high brightness, contrast, electronic burns and so on, the picture tube is very precise, the instantaneous impact will damage it, prone to such problems as broken filament, crack tube neck, air leakage and so on; High temperature easy to make the power switch tube damage, the higher the temperature switch tube is more prone to breakdown damage, Dust easily makes the high-voltage circuit spark.

High brightness and contrast will reduce the life of the phosphor, so that the display will not be used for a few years would be "no light", the color is bleak; electronic burns refers to the display of the failure of the bright line and bright spots, it is the most damage to the screen, so that there is a noticeable burn marks on the display, the impact of bright lines and Do not continue the boot.

　　Nine, Jian Pan

It is afraid of moisture, dust, drag. Now most of the keyboards are made of plastic film switch, that is, the switch is composed of three plastic film, the middle one is a hole with the insulating film, on both sides of the film on the plating of metal lines and contacts, moisture corrosion, dust will make the keyboard contacts bad contact, operation is not the spirit. Drag and drop easy to break the keyboard line, so that the keyboard failure.

　X. Mouse

This "little mouse" is the most afraid of dust, strong light and drag. Small ball and roller on the dust will make the mouse machinery parts operation is not good, strong light will disturb the dust will make the mouse machinery parts operation is not good, strong light will interfere with the photoelectric tube to accept the signal, pull will also make "rat tail" break, so that the mouse failure.
