Normal is not bad, but does not rule out other cases.
To provide you with some clues, you have to go to the exclusion.
1, poor heat dissipation: the display, power supply and CPU working time is too long will lead to crash, to the fan dust, oil.
2, dust killer, poor contact: too much dust in the machine, poor contact will cause dead failure. Regularly clean the chassis, all connections will be inserted tightly and firmly.
3, memory stick failure: mainly loose memory stick, memory chip itself due to the quality, should be based on the specific circumstances to rule out the memory stick contact failure, if the quality of the memory stick is a problem, you need to replace the memory to solve the problem.
4, CPU overclocking: Overclocking improves the working frequency of the CPU, and at the same time, may make its performance unstable. The BIOS also allows you to adjust the CPU back to its normal frequency.
5, hard disk failure: If the remaining space on the hard disk is too little debris is too much, so that the machine is very easy to run when the crash. To develop a good habit of regularly organizing the hard disk, remove junk files in the hard disk. Hard disk aging or due to improper use of bad channels, bad sectors, to use tools and software to troubleshooting, such as serious damage can only replace the hard disk.
6, hardware and software incompatibility: three-dimensional software and some special software, may not be able to start or even install properly on some microcomputers, find and remove incompatible hardware and software.
7, the driver installation error: when some hardware such as graphics card driver if the installation error, in the startup system to the desktop will suddenly enter the blue screen or black screen and crash, check, delete the problem driver.
8, application software defects: If you run this kind of buggy software may make the system crash or can not start normally, encounter this situation should find the latest version of the software or simply uninstalled.
9, virus infection: viruses and Trojans can make the computer work dramatically reduced efficiency, resulting in frequent crashes. At this point, we need to use antivirus software such as KV3000, Kingsoft, Rising Star, etc. to carry out a comprehensive anti-virus. Before checking the virus, to ensure that your antivirus software is the latest virus database. You can click on the "Upgrade" button to upgrade to ensure that you can detect the latest viruses.
10, start too many programs: this makes the system resources exhausted, in the Internet surfing, do not open too many browser windows, otherwise it will lead to insufficient system resources, causing the system to crash. If your machine's memory is not very large, do not run programs that take up a large amount of memory, such as Photoshop, otherwise it is easy to die when running.
11, illegal operation: with illegal format or parameters to illegally open or release the program in question, will also cause the computer to crash, keep in mind the correct format and related parameters, do not arbitrarily open and release unfamiliar programs, to shut down the computer in the correct order of operation.
12, mistakenly deleted system files: In the Windows operating system there are many system files, sometimes users will mistakenly delete some system files as garbage files, if it is more important system files, then the system will crash, or even crash. You can use the Windows Installation Disk's "Fault Recovery Desk" feature to fix it.
13, CMOS settings are not appropriate: such as hard disk parameter settings, mode settings, memory parameter settings are not appropriate, resulting in the computer can not start. The BIOS is a powerful tool to ensure the correct BIOS setup.
2. computer time with a long time need to clean the host
disassembled. Frequently sweep the cleaning props Ready:
The following introduction to a variety of good cleaning props, so you can do more with less, do things more easily! Due to the information products taboo moisture and scratch, people clean up with a wet rag do not use a direct wipe computer and peripheral products, so as to avoid water droplets into the internal machine, resulting in a short circuit; generally wipe with a dry cloth, encountered more difficult to clean the dirt, can be used to spray a water sprayer lightly sprayed with a little water on the wipe on the treatment.
A small wiping step allows you to save more energy: the popular dusting paper used on paper mops, combined with small tools in life, can allow you to clean up the computer and the surrounding more labor-saving. Sometimes, home space is small, the computer and neighboring items too close, or up and down the compartment gap is not good to move to clean up, as long as the ruler to take a 30 centimeters or more, tearing a dusting paper to the ruler wrapped up, you can go deep into the crevices back and forth to wipe to remove the dust. If it is like the item itself, such as computer connection port holes, TV game Xbox shell on the small interval, the people can depending on the size of the seam, take a toothpick or chopsticks, the dust paper wrapped on it, and then one-way wipe, you can easily remove the dust.
Now you're ready to get started! 1. Computer screen Desktop computers, notebook computers, the screen is most afraid of scratches, you can first clean the camera lens with a special dust blower, the dust on the screen to blow off, and then use microfiber wipes to wipe. When wiping the screen surface, it is recommended that the public from the center of the screen to both sides of the push away one-way wipe, do not wipe back and forth, so that the screen is more clean. When people clean up the screen of different machines, do not be lazy a "cloth" in the end, or it may be cleaned up by the previous dust particles brought to the top of another, and even scratch the surface of another. To clean this microfiber cloth, can be washed by hand or thrown into the washing machine cleaning, do not use soft essence, so as not to affect the fiber descaling ability. If you use a long time to feel the wipe clean cloth descaling ability is not as in the past, can be soaked in hot water for about ten minutes, so that the fiber to restore the elasticity.
2. Keyboard, mouse Usually manufacturers recommend not to eat and drink next to the computer, but people play computer games or night in front of the computer to catch up with the work, it is inevitable that will not be able to help but eat, so that the keyboard is often some cookies, hair and other crumbs, or the mouse on the stains and so on. The public can use the workshop dusting paper, single-direction first keyboard on the larger hairs, dust gently swept away, and then use a blowing cleaner or a small vacuum cleaner designed for the fine cracks, patiently between the keys and the keys of the dust blowing or sucking up. If you have a keyboard or mouse with water or dirt, you can use a water sprayer to spray it on a cloth or use a cotton swab with a little bit of water to wipe it off directly, avoiding making the cloth or cotton swab too wet; as for the roller mouse, after a year of use, the ball at the bottom of the mouse will often adsorb hairs and dust, according to the manufacturer's instructions, remove the ball and wipe it off, and use a cotton swab to gently remove the fine particles on the inside of the mouse.
3. Computer and peripheral shell information products avoid moisture and scratch, clean up computers, printers, scanners, hard disk enclosures, network connectors and other shells, as long as you take a dry cloth to wipe in one direction, you can remove the surface of the dust; chassis rear connection to the various computer interface equipment jacks are often gathered dust, due to the place of a more narrow, you can use the blowing cleaner or mini-vacuum cleaner remove the dust. The following is an example of how to do this.
4. Inside the computer If you have the concept of a desktop computer interior, you can consider an annual cleaning of the interior of a personally assembled computer. Computer due to fan cooling, long time will often introduce dust accumulation in the interior, the people unplug the power supply, disassemble the chassis, the adapter can be labeled with a label number removed, in order to clean up after the number of positions according to the restoration; motherboard, the interface dust can be used to dry old toothbrush cleaning, if the adapter joints with the oxidation of the spot, can be used to erase the eraser to blow thoroughly, preferably after the opening of the main chassis, the main board and the motherboard on the plug-in all removed, and then use the eraser to remove the dust, the main board and the motherboard to remove the dust. The best way to do this is to open the main chassis and remove all of the motherboard's plug-ins, and then gently dust with a soft-bristle brush.
For plug-ins, first remove the sand and then use an eraser (used by schoolchildren) to polish the gold finger, and then install the same back to the motherboard can be. For the power box, if the warranty is over, you can also unscrew the four screws on the back of the host, and then unscrew the four screws on the power box, remove the circuit board, the dust and sand brushed clean before installing the restoration. If the light of the hairdryer blowing is not a complete solution to the problem of sand removal.
The computer is afraid of static electricity, not afraid of dust, the main thing is that when you get the hardware to ensure that your body is not static electricity The simplest way is to move the hardware before touching the chassis with your hands
3. computer hosts for a long time without opening the what is the reason
Computer hosts for a long time without opening the what is the reason for long periods of time without using the power supply and the motherboard power supply both. Part of the electrolytic capacitors do not get charged and discharged for a long time! It reduces the performance, making the current drop, the load capacity becomes poor. The reason for this is that the power supply and the motherboard power supply are not charged and discharged for a long time. So computers, monitors, televisions and other equipment is best ten days and a half months to boot, a few minutes on the line. The power supply and motherboard power supply electrolytics, however. But the power supply and motherboard power supply electrolytic capacitors can be replaced, and very cheap, less than 3 yuan a, replaced, or the same old, the same performance! You can use a multimeter 'capacitance file' online testing, unqualified replacement. Observation with the eyes is also very effective ------ bulging, leakage, discoloration certainly need to be replaced.
Replacement method, find a good power supply installed to try to immediately rule out a suspect, and then test the motherboard power.
The reason why the computer host is not open for a long time is that most of the above reasons.
Of course, in addition to the above, the computer host for a long time without opening what is the cause of memory sticks, graphics card gold finger oxidation need to clean very common.
4. computer chassis for a long time inside the dust how to clean ah
fan oiling and chassis dust cleanup
Specific practices and precautions:
First, the preparatory work and tools: a single-sided blade, a flat and cross-port screwdriver each, a small brush, a pair of tweezers, a pair of sharp-tongued pliers, an eraser, a lubricating oil a little (the best use of lubricating oil and butter yourself). It is best to use lubricants and butter to mix their own, sewing machine oil is too thin), but also a blowing tool, can not use a pump (may have oil) and hairdryer (static electricity and electromagnetic interference), in addition to prepare a small box for small screws.
Second, the specific method:
1, open the chassis, pay attention to the oil chassis designed to buckle and, pay attention to the opening method, may use a screwdriver and sharp-nosed pliers, remove the screws into a small box?
2, with a blowing tool and a small brush to clean up the dust, a small brush can be brushed to the capacitors and other parts of the gap, blowing tool can be blown by the card slots;
3, remove the CPU, graphics card and power supply fan, the power supply fan is more difficult to remove, pay attention to the power supply can be unplugged first plug obviously dealt with after the unplugging of the former attention to make a good mark, before the operation of the operation, be sure to pay attention to discharge their own static electricity, you can use your hands to metal objects, you can use your hands to remove the static electricity. Do not touch the chip part of the card.
At this point, our refueling and cleaning work is over, and then installed in reverse order according to the removal of the machine, (the installation of small screws do not fall into the gap, such as falling into the available tweezers to take out) the work is complete.
Important note: If your computer is not over the warranty period, and the manufacturer agreed to repair at home, please try not to carry out this operation, such as requesting the computer to send for repair, you can take this approach, but you can pay attention to the following matters in order to ensure that their computers can still enjoy the warranty (a lot of manufacturers stipulate that the chassis is automatically lost once opened the warranty), with the hairdryer to open to the low-temperature block, evenly blowing the chassis seals, seals, will slowly and automatically open, and so on. The seal will be slowly and automatically uncovered, and when the work is finished, glue oil and then stick, uncover the fan label with a single-sided blade is also the same reason, because the fan is generally plastic products, can not be blown with an electric fan.
