#台式电脑最容易坏的配件是什么? #
Do you know which of the computer accessories is the most prone to breakage?
We have all used computers, and we have also encountered computers that suddenly malfunction, in our use, which computer accessories are most likely to have problems? Some people must say that the system is the most prone to breakdown! It's just that the system belongs to software, and today we only discuss hardware problems!
1. Keyboard
No matter what you do with your computer, you can't do without a keyboard. The keyboard is a basic input device, and it is inseparable from the maintenance and operation of the computer. If the computer is used for work, then there is one less of 26 letters, and if the computer is used for playing games, it only needs to go up, down, left and right (and WASDX).
Because we use a lot of keyboards, it is also common to drink some water to the keyboard once in a while, so as long as the keyboard gets water, it needs to be replaced. Then the keyboard often types or is in a bad mood, and you have to take a beat, so the keyboard breaks faster.
Damage Index: ★★★★ ☆
2. Mouse
The mouse is also one of the essential input devices for operating the computer, and it is impossible to do without a mouse. In the old days of wired mice, the cable between the mouse and the host would be damaged due to long-term wear or folding due to frequent dragging. Today's wireless mouse is already a wireless mouse that can be charged at any time, without the constraints of signal cables, and it is more convenient to use.
Damage Index: ★★★★ ☆
3. Fan
In order for a computer to work properly, it is inseparable from cooling fans, CPU cooling fans, graphics card cooling fans, and chassis cooling fans. Because the cooling fan will work as soon as it is turned on, if there is too much dust in the use environment, the fan will generally be replaced in three or four years.
After a long period of use, the oil-impregnated bearings will make noise when the fan rotates and the speed drops, which will affect the heat dissipation effect and even cause damage to the graphics card.
Damage Index: ★★★ ☆☆
4. Hard disk
The hard disk is used as external memory to store user data and system programs.
Mechanical hard disk is a mechatronics product, which is prone to bad sectors after a certain period of use, and partition loss occurs and files cannot be read. There are also mechanical hard disks have SMART warning function, but this function needs to be turned on in the computer BIOS, and it will alarm when the hard disk is detected to age to the warning line, reminding users to back up data in advance.
Solid-state drives are now using QLC flash memory chips, as long as you buy a well-known domestic brand, what do you have to worry about with a five-year warranty hard drive!
Damage Index: ★★★ ☆☆
5. Power supply
Now the power supply of the host is a switching power supply, as long as you choose the right power supply when assembling the computer, there is enough margin, and there is no problem with a power supply that can be used for seven or eight years.
The selection of the host power supply is as much as possible to buy well-known brands, and the rated output power of the power supply is 20% greater than the total power consumption of the whole machine. If the host power supply works at full load for a long time, the heat generation of the chip will be large, and the service life of the chip will definitely be attenuated when working in a high-temperature environment for a long time. There is sufficient margin, which can not only ensure the full load operation in case of emergency, but also ensure that the power supply does not work in a high-temperature environment for a long time.
Damage Index: ★★ ☆☆☆
6. Memory
In actual use, there is not much damage to the memory, but the gold finger of the memory is too easy to oxidize, so there are more problems. There are also some very strange problems with memory, such as:
1) Two slots, any memory can be plugged into any memory slot can be turned on normally, but it cannot be started when two memory are used at the same time.
2) The black screen does not start every time you turn on the power-on, but you can turn on the machine by unplugging the memory and plugging it in.
3) The motherboard has four memory slots, generally only one memory when inserting the first, when there are two memories inserted 13, but some machines only have 1 memory when inserting the first slot is not lit, can only insert 3 slots.
Damage Index: ★★ ☆☆☆
7. Graphics card
Nowadays, computers use more integrated graphics cards, because integrated graphics cards can already meet the needs of office use and online games, and the probability of problems with integrated graphics cards is very low.
Friends who play stand-alone games need to use high-end discrete graphics cards, because discrete graphics cards are the most power-consuming components in computers, a graphics card is generally above 200W, and some can reach 450W, so discrete graphics cards are also one of the most problematic accessories in computers.
For a graphics card to work stably, it must ensure good heat dissipation. As long as there is a problem with the cooling fan, the graphics card will easily burn out.
Damage Index: ★★ ☆☆☆
8. a motherboard
The motherboard is the platform of the whole computer, and all other accessories run on the motherboard, so the quality of the motherboard directly determines the reliability and stability of the whole computer. At present, the motherboards commonly used to assemble computers are still ASUS, Gigabyte and MSI, and the motherboards of these three brands are still good, as long as the humidity and temperature of the working environment are normal, it can still be guaranteed to be used for seven or eight years.
If your computer is going to work in a humid environment such as a boat or a lake, or in a greenhouse, you must consider dehumidification or moisture-proof treatment of the motherboard, otherwise the motherboard, hard disk, and memory will corrode in one or two years.
Damage Index: ★ ☆☆☆☆
9、CPU
THE CURRENT CPU CAN REALLY BE SAID TO BE INDESTRUCTIBLE, AND INTEL'S CPU FRAGMENTS ARE NOW UNDER A THREE-YEAR WARRANTY. It's really hard to encounter CPU damage in actual repairs, and it's about to catch up with the 5 million jackpot.
JUST BECAUSE INTELCPU ADOPTS A FLAT PINLESS PACKAGE, THE CONTACTS ARE EASY TO OXIDIZE IN LONG-TERM USE, RESULTING IN POOR CONTACT WITH THE CPU SOCKET, WHICH CAUSES THE PROBLEM OF NOT TURNING ON AND NOT STARTING. Ordinary users need to pay attention when repairing to prevent being deceived.
损坏 index:☆☆☆☆☆
In fact, there is an important component missing, which is the computer case. The chassis is iron, and it will definitely not break, but the panel switches and USB sockets on the chassis are easy to break, and there are many broken ones, and it is estimated that everyone has encountered them.
