Computer Ten things are afraid of what

First, hard disk

The most fear of the hard drive is vibration, large vibration will let the head components hit the disc, scratches can be bad things, repair are not easy to repair, the most important thing is that your data can not be your-painstaking care yo!

Second, the motherboard

The main thing that the motherboard is afraid of is electrostatic and deformation. Static electricity can damage BIOS chips and data, damage to a variety of MOS transistors based on the interface of the circuit, they are bad, all the "user" (inserted on its board or devices) are not found each other, because they are connected by the bus, control chipset, control gate circuit to coordinate and implement. The deformation of the Board may cause the circuit board fracture, component off welding, the circuit on the board is very dense, broken you can not find.

Third, CPU

CPU is the heart of the computer, it is most afraid of high temperature and high voltage. High temperature easy to make the internal lines of electronic migration, shorten the life of the CPU, high voltage is more dangerous, it is easy to burn your CPU, overclocking should be as far as possible not to improve the core voltage to help excess, because this is not worth the candle.

Four, memory

Memory is more afraid of overclocking, once the required frequency is not reached, very easy to appear black screen, and even heat damage.

V. CD-ROM drive

The optical drive is most afraid of dust and vibration. Dust is the laser head of the "killer", vibration will also make the bald-headed "disk", damaged bald. Another coarse optical disc is also the enemy of the optical drive, it will increase the burden of the bald servo circuit, speed up the movement of the wear, speed up the aging of the laser tube. Believe it or not, now the popular DVCD disk is the most dangerous optical drive of the enemy, because it's light point distance and ordinary optical drive design standard point distance is much smaller, optical drive reading it is like a nearsighted person to see the teeny-tiny print as difficult, perhaps the day will be "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 component translocation, the floppy drive can be troublesome, the calibration head must use a dedicated instrument, manual correction is not impossible, it requires great patience and meticulous effort.

Seven, power supply

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

Eight, monitor

The monitor is the interface that communicates with the person, also is the power consumption of the whole computer system, is the most easily damaged part. It is most afraid of shock, high temperature, high pressure, high brightness, high contrast, electronic burns and so on, the picture tube is very precise, instantaneous impact will damage it, easy to occur such as broken filament, crack pipe neck, air leakage and so on; High temperature easy to make power switch tube damage, the higher the temperature switch tube more easily breakdown damage, so its heat sink is very large; The dust makes the high voltage circuit ignite easily.

High brightness and contrast will reduce the life of phosphor, so that the display in a few years will be "no light", the color is dim; Electronic burns refers to the display of the failure of the bright line and bright spots, it on the screen of the most damage, so that there is obvious burn marks on the screens, affecting the bright line and off the bright spot, should be immediately sent to repair, Don't continue to boot up again.

Nine, Jian Pan

It is afraid of moisture, dust, drag. Now most of the keyboard uses 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 plated with metal lines and contacts, damp corrosion, dust contamination will make the keyboard contact poor, operation is not. Drag and drop easy to break the keyboard line, so that the keyboard failure.

Ten, mouse

The "Little Mouse" is most afraid of dust, glare and drag. Small balls and rollers on the dust will make the mouse mechanical parts operation is not, strong light will interfere with the dust will make the mouse machine parts operation is not, strong light will interfere with the photoelectric tube reception signal, pull the same will make "rat tail" break, so that the mouse malfunction.
