What's the cause of mine machine crash

1. Generally speaking, press the three keys of Ctrl + Alt + delete
the specific operation methods are as follows:
1. Judge that the machine is in a dead state. The way to change the state is to press the NumLock key to see if the num light will change the state with the pressing of the key. If it doesn't change, it will be in a crash state
2. If the machine is in a dead state, press the CTRL and ALT keys with your left hand, and then press the delete key with your right hand while keeping pressing
3. The system will restart.

2. This is very necessary, installed a good graphics card without driver will greatly rece the performance of the graphics card

excessive overclocking

e to the use of components with higher technical parameters, some graphics cards have excellent overclocking capability, so many players advocate overclocking graphics cards to improve performance. However, there are both advantages and disadvantages. Overclocking can also lead to a significant increase in the heat of the chip. When it reaches a certain level, it will cause the problem of splash screen and crash. Even if not, it will also cause instability in some applications, such as games. Therefore, overclocking must be moderate. 4

3. Hello LZ, there are many reasons that may lead to computer crash, the following is my opinion:
1. Ensure the correct BIOS settings. The settings in BIOS must be appropriate. The wrong BIOS settings will cause you to crash when running Windows
2. Check the contact of computer accessories frequently. In the case of poor contact between the board and the main board, the system will crash. Therefore, when replacing the computer accessories, the board and the main board must be fully contacted
3. Clean the chassis regularly. Too much st will cause poor contact between boards and cards, causing the system to crash in operation. Therefore, the chassis should be cleaned at any time, and too much st should not accumulate in the chassis
4. Don't use the disk or floppy disk of unknown origin easily. For the attachment in the mail, check it with anti-virus software before opening it
5. Shut down according to the correct operation sequence. Do not turn off the power before the application software is running normally, otherwise the system files will be damaged or lost, resulting in a crash ring startup or operation
6. Avoid multitasking at the same time. Do not run other software ring disk cleaning or checking the hard disk with antivirus software, otherwise it will cause crash
7. Don't be too innovative. All kinds of hardware drivers don't have to be updated at any time, because the newly developed drivers often have bugs, which will damage the system and cause the system crash. The latest is not necessarily the best
8. When uninstalling the software, use the built-in anti installation program or the installation / uninstallation method in windows. Do not delete the program folder directly, because some files may be shared by other programs. Once these shared files are deleted, the application will be unable to use and crash
9. When setting hardware devices, it is better to check whether there is reserved interrupt (IRQ), and do not let other devices use the interrupt number, so as to avoid causing interrupt conflict and causing system crash
10. When surfing the Internet, do not open too many browser windows, otherwise it will lead to insufficient system resources and system crash
11. If your machine memory is not very large, do not run programs that occupy a large memory, such as Photoshop, otherwise it is easy to crash
12. For system files or important files, it is better to use implicit attributes, so that the system will not crash e to the deletion of these files e to wrong operation
13. When modifying the master boot record of the hard disk, it is better to save the original record first to prevent the original boot record from being unable to be recovered e to the modification failure
14. Generally, CPU, graphics card and other accessories should not be overclocking. If overclocking is really necessary, pay attention to the temperature of the card after overclocking. CPU, graphics card and other accessories work under abnormal frequency and temperature for a long time. If it is light, it will automatically restart or crash, and if it is heavy, it will burn CPU, graphics card and motherboard

I hope you can check your computer carefully for the above problems~~

4. 1: The host's heat aging or damage causes the host's temperature to overheat and the automatic protection function to start. Therefore, the host will shut down automatically.
2: some hardware in the host is damaged or loose, which causes the host to shut down automatically.
3: when you play games, you accidentally press the
power
key, which is the power key. You can't press it indiscriminately. Pressing it will cause the host to shut down.
4: computer poisoning. (it is recommended to do a comprehensive antivirus)

5. There are six reasons
first, there is a problem with the power supply. For example, there is a problem with the high-voltage rectifying and filtering circuit of the power supply. The power supply is bulging and leaking from the large capacitor. When the power supply is turned on, it can still be turned on. After a while, e to the lack of power supply from the large capacitor, the power supply starts to protect itself, so it is suggested to replace the power supply, Or repair the large capacitance and other components in the power supply.
the second problem is the memory and graphics card. For example, the memory chip of the integrated block of the memory and graphics card has a problem, resulting in a crash. The solution is to dial out the memory and memory, be sure to remember the direction, and then use the eraser to aim at the gold finger (that is, the part with the copper chip) and rub it back and forth, Then replace a slot and plug it back in. (do not replace the graphics card) ok. If there is still a crash, repair the memory and the video memory chip of the integrated block of the graphics card. This can be solved.
the third is: your CPU fan is stuck or the clip of the radiator is loose. This is because your fan is stuck by st or the fan is broken, and the CPU can't cool down, When the temperature reaches the set temperature of the motherboard, the motherboard startup protection will shut down, so it will crash after a period of time. When the clip of the radiator is loose, it will be the same as the above reason,
treatment method: clean the st of the CPU fan, if the fan is broken, replace the fan, and re install the radiator to ensure that the clip is tight, Motherboard Components problems, such as power IC, field effect transistor, CPU power supply problems, I / O is also a virtual soldering, and so on, there will be a crash, motherboard crash phenomenon is relatively common. There is no need to repair these electronic components of the motherboard.
the fifth is that there is something wrong with the computer's operating system, such as poisoning, lost files, etc., and it is OK to reload the system.
the sixth is that there are too many bad channels on the hard disk. When the hard disk reads these places, it can't read down, causing it to jam, and after a while, it will crash, The solution is to use HDD to check and repair the bad track or replace the hard disk.

6. The simple method is software first and then hardware. Download the win cleaning assistant to check and kill the Trojan horse, restore the system or reload it, or not. Check whether it is caused by hardware problems

is the original card, crash or slow response? What did you do before the crash or slow response? What software plug-ins or patches have been downloaded? Did you upgrade the hardware If the card before the download of the software or a patch to try to uninstall all) please talk about it in detail

1. There are many antivirus software installed, and all of them turn on monitoring. If you turn on monitoring less or not, you can always check and kill viruses
2. If the software or driver is not compatible with the system, the driver should be reinstalled or upgraded
3. If there is a system problem or a Trojan horse, check and kill the Trojan horse, restore the system or reload it (download win cleanup assistant to check and kill the Trojan horse)
4. Memory, graphics card, and unstable voltage can also cause crash (if the memory is too small, upgrade the memory)
5. Over high temperature of common hardware such as CPU or graphics card is most likely to cause card crash
6. If the hard disk has a bad track, use software to repair the bad track, format the hard disk, re partition and re install it, and replace it
7. Upgrading hardware causes incompatible crash
8. There are too many junk files and too many disk fragments
9. If it can't work all the time, it's recommended to carry out maintenance

the computer crash or card is usually caused by hardware and software. It is easy to solve the problems caused by software, driver and system. It is not easy to solve the problems caused by the incompatibility of hard disk or hardware. It is also hard to find the source of the fault. If so, it is better to carry on the maintenance. It is up to you to repair or not. At least, find out where the fault is.

7. Alas! I think everyone who uses a computer will encounter this situation, especially those who often run various large software or run many software at the same time. For game players, it is a pity that the game progress is not saved. For those users who are editing or processing important data but do not save it, the "pity degree" will be greater...
crash is the most common kind of computer failure, and it is also the most headache. Because the fault point can be large or small, and
and there are many reasons for the crash, in addition, the fault phenomenon is also diverse, but the author puts the fault phenomenon into two categories: regular crash and random crash. As for the subjective performance of the crash phenomenon, most of them are "blue screen", the screen "freeze" has no response (at the same time, the mouse and keyboard can not input), often illegal operation (or forced to close a program), and they have lost their response before entering the operating system

at first glance, it seems that the crash is very "terrible", but the cause of the crash can never be separated from the hardware and software. Therefore, as long as we know the specific cause of the crash, we can completely "smooth out" the crash, or even eliminate it. Although "crash" articles have been published in some newspapers and periodicals, most of them are not comprehensive enough and have some misunderstandings, which usually can not solve any problems. Therefore, the author will classify the "crash" causes and treatment methods (combined with the fault phenomenon) according to the "prerequisite" of the crash, I hope it will help you

the first kind of situation: in the normal use of the situation, occasionally and increasingly frequent crash, or after a sudden crash occurs frequently

1. Frequent "crash" failures caused by too much st

after a new computer is used in general cities in China for about a year, there will be a lot of st inside it. If it enters the slot of a board, it may cause the board to have poor contact and crash or other failures, and it often crashes for no reason

in addition, too much st in the machine will have a bad impact on the heat dissipation of some important computer hardware equipment. If the heat dissipation of important hardware such as CPU and graphics card is not good, it will naturally cause the blue screen or splash screen or freeze frame or black screen crash. Although there is no rule for this kind of crash phenomenon, the longer it is used, the more frequent it will crash. If there is too much st on the floppy drive head or the laser head of the optical drive, it will lead to the difficulty of reading and writing the disk, and even cause the computer blue screen to crash

so you'd better st the computer once a year. Of course, if you are just a beginner, you need to find an old hand to operate it for you, so as not to cause other faults. Of course, keeping the computer room clean is also a very good measure

, frequent "crash" failures caused by poor heat dissipation of some hardware

CPU, graphics card, hard disk, power supply and other hardware have very large heat in their work. Fortunately, most of them have their own cooling fans, so they usually do not crash, But if the st on the fan is too much, or the lubrication is poor, or the wear is serious or the aging is serious, then the heat dissipation of these hardware devices will have problems. Over time, with the continuous deterioration of the situation, there will be frequent crashes or restarts after a period of time

so you should check the working condition of the fans in the computer regularly and lubricate them regularly to avoid such faults. If there is a frequent crash every time you use it, don't worry. Just open the chassis and observe which fan is abnormal when the computer is running (such as loud noise or obviously slow down or stalling) or which hardware temperature is abnormal (such as touching a chip or heat sink with your hand is very hot), and then do the corresponding treatment

in addition, too long working hours can also lead to computer crash. I remember that once when I went to work in Haier instry and trade, I happened to encounter a black screen crash of Haier P Ⅲ computer in use without any reason. The operator and several colleagues tried many ways, but they didn't solve the problem. Just when she learned that I was in instry and trade, she found the author, because it was more than 4 p.m, So the author suspected that the crash was caused by too long use time, so he pulled the power plug of the computer from the multi-functional power socket, and then told her not to plug it in first, and let her connect the power supply and then turn it on when the author finished. After observing for a while, the author found that there was no crash again, so he decided that the machine was normal. Although the fault has been repaired (it has not been reported to be committed again so far), the fault point has not been determined, because the power supply and CPU are "suspected", but one thing is certain - the fault is caused by the high temperature of a hardware

3. There is a conflict in the memory, which leads to an unexplained "crash" fault.

this situation is easy to occur when multiple software are running at the same time. Although sometimes many software are running at the same time and everything is normal, sometimes they suddenly crash for no reason. It is very normal when these applications are running again after restarting, In fact, many of these failures are just fake crashes, most of which are caused by memory resource conflicts - application software runs in memory, but some application software will use the same memory address with another software at the same time e to design reasons, which will lead to conflicts. This type of crash is usually a freeze or restart or a blue screen or a prompt for "illegal operation" or loss of response

this kind of fault can only be avoided, but not eradicated, that is, try not to let many programs run at the same time, and it is better to turn off the software that has not been used immediately. In addition, try to use famous software to avoid this kind of fault. Of course, if you are patient, the computer may wake up from suspended animation later. Once, when I was playing "biography of the heroes of the Three Kingdoms", the computer crashed (I started a lot of programs at the same time), but I just waited for half an hour (I went to eat a plate)<

4. The "crash" fault caused by overclocking

many DIYers like to overclock all kinds of hardware, some of them are single CPU, some of them need to overclock everything, because they will pay attention to the stability when overclocking - otherwise they can't use the computer normally, So there won't be any problem in a period of time after overclocking, but after using a stage, the system will become unstable with the increase of st and the power of various fans. After all, the more the fans use, the smaller the wind. At this time, if you run large software (such as 3D games) for a long time or perform multi task operation, So CPU and other chips are likely to appear electronic drift phenomenon and cause frequent crash phenomenon. Fortunately, there is a feature of this kind of crash failure - as long as you turn on the CPU cooling software (almost all users are using it) and do not use large software, you will not crash, otherwise you may take some detours

so although overclocking can improve the system performance, it will also make its stability worse. The solution, of course, is to adjust the working frequency of each equipment back to the default value. If you have to exceed it, you must regularly check the cooling system or strengthen the cooling work (such as replacing a brand-name fan with higher power), and do not exceed the frequency too high (preferably not more than 30%)
, irregular "crash" phenomenon caused by poor connector contact

this kind of fault is easy to distinguish, because no matter how small a program you run, it may crash, even sometimes it will freeze at startup, and sometimes it will not crash even if you run a large program for a long time. So the fault point of this kind of fault is very easy to find. Usually, you just need to remove all the things that can be removed (such as graphics card and power plug, etc.) for cleaning, and then plug them in. Of course, if there is any rust, you need to remove the rust or replace the rusty part with a new one

6. Frequent "crash" failure caused by memory mole failure

as the working frequency of memory mole becomes higher and higher, its calorific value also increases, and the stability is relatively poor. Generally, memory mole failure refers to memory mole looseness, false soldering or memory chip damage or instability

if you often appear in the windows operating system with memory related illegal operation and other crash phenomenon, or directly prompt the registry error and restart the machine, then we need to check whether the memory mole is loose or sty and has entered the memory slot, if no exception is found, you need to try to change the memory mole, If everything is normal, it means that the memory mole itself may have a fault. Of course, sometimes long-term overclocking will cause the memory mole to age and become more and more unstable

7. Too little free space or too many disk fragments on the hard disk will also lead to "crash"

because some large applications need a lot of memory when running, if the physical memory is insufficient, the virtual memory on the hard disk will be used. At this time, if the free space on the hard disk is too little, it may cause crash. In addition, if your computer does not defragment the hard disk for a long time, it will also make the system resources nervous and crash. Of course, if there are too many junk files in the hard disk, it will also make it difficult for the hard disk to find files and crash. The performance of this kind of failure is also quite special - usually when the hard disk is continuously "Crazy" to read and write the disk, it will suddenly freeze or blue screen crash

therefore, you'd better set the virtual memory to the partition with large remaining space, and regularly clean up all kinds of junk files and disk fragments

8. Frequent "crash" failure caused by hard disk failure

if the hard disk is seriously aged or vibrated ring operation, or if there are logical or physical bad paths or bad sectors, then the computer is prone to frequent crash failure ring operation. As for the best way to deal with it is to replace the hard disk. Of course, if it's just a logic error, you can still use various repair software to repair it. Because some of these faults are not easy to find, so I suggest that you regularly carry out "disk scanning program" (once every two weeks), so that you can have a clear idea of your hard disk

the author has an article on "Tianji myhard" dedicated to the use and maintenance of hard disk. If you are interested, you can have a look, so that you can avoid hard disk failure
9. Frequent "crash" failures caused by inferior accessories

such failures are mostly caused by the use of miscellaneous brand procts or second-hand procts or repaired procts. If it is a new computer, it is better to eliminate the resource conflict in the "device manager"

8. Software crash: enter a dead cycle and use up CPU resources.
Hardware crash: if a hardware overheats or breaks down, the hard disk will crash
