What if the computer doesn't start?

Most friends who use computers should have had problems with computers that could not be started. What if the computer doesn't start? computer users should be based on the symptoms of diagnosis and treatment, to understand the process of computer start-up, fault is good to judge. Today, the small series of the system will discuss with you more computer can not boot problem, hope that this article can let you know in the daily use of the computer when the computer can not start the solution.

Computer software and hardware problems can cause the computer will not start, then how to determine whether the hardware or software issues, has become a lot of netizens more headaches.

Hardware problems cause the computer can not boot usually show the boot time box alarm sound, chassis fan abnormal operation and so on; from the maintenance of computer experience, memory, power and video card cause the computer can not start a little more. Bad memory contact, motherboard burnout, motherboard capacitor slurry, graphics card is not compatible and so these are the hardware causes the computer can not boot, we in the actual processing will be one by one.

Software problems cause the computer can not start usually does not appear above the computer alarm phenomenon, generally occurs in the computer after the self-test, and even the operating system interface after the appearance of black screen and so on. NTLDR lost, system-driven files lost, even computer poisoning and so on are the software caused by the computer can not boot.

　　First, the hardware aspects of the problem

1. Bad heat dissipation

Monitors, power supplies and CPUs are extremely calorific in their work, so it is important to maintain a good ventilation condition, and if the display is overheating, it will cause color, image distortion and even shorten the display life. Too long working hours can also cause power or monitor heat dissipation caused by computer crashes. CPU cooling is related to the stability of the computer operation of the important problem, but also the thermal failure occurred in the "hardest hit", so to protect

Proof of its good heat dissipation effect.

2. Improper movement

In the process of computer movement by a large vibration will often make the machine internal devices loose, resulting in poor contact, causing computer crashes, so mobile computers should avoid violent vibration. Usually in the discovery of the crash can also check whether the board is loose, can be pulled out and plug again.

3, Dust Killer

Excessive accumulation of dust in the machine can also cause a panic failure. For circuit boards, dust is tantamount to a time bomb. In addition, such as floppy disk head or optical drive laser head contaminated with too much dust, will lead to read and write errors, serious will cause computer crashes. Therefore, the computer room dust-proof must always pay attention to.

4, the equipment does not match

such as motherboard frequency and CPU frequency mismatch, the old motherboard overclocking will FSB set too high, may not guarantee the stability of the operation, resulting in frequent panic. This is mainly due to the compatibility of various parts of the matching did not do a good job, therefore, in the purchase of compatible machines, you can ask more knowledgeable people to help choose Accessories.

5, hardware and software is incompatible

Three-dimensional software and some special software, in some computers can not normally start or even install, which may have software and hardware compatibility problems.

6, the memory piece failure

Mainly is the memory strip loose, the virtual welding or the memory chip itself quality is caused. Should be based on the circumstances of the memory to exclude contact failure, such as reseating. If there is a problem with the quality of the memory bar, you need to replace the memory bar to resolve the problem.

7. Hard Drive failure

Mainly hard disk aging or due to improper use caused bad, bad sector. This makes it easy to panic when the machine is running. The fault on the hard disk must be repaired and repaired with special tool software and maintenance personnel, if the damage is serious, the hard drive can only be replaced. In addition to the motherboard that does not support UDMA 66/100, should pay attention to the CMOS hard disk operation mode setting.

8, CPU overclocking

CPU overclocking increases the CPU's operating frequency, and can also cause its performance to become unstable. The reason, the CPU in memory to read data faster than the speed of memory and hard disk exchange data, overclocking makes this contradiction more prominent, aggravated in memory or virtual memory can not find the required data, this will appear "abnormal error." The solution is relatively simple, is to let the CPU back to the normal frequency.

9. Hardware resource conflict

This is due to a conflict in the settings of your sound card or video card, causing an exception error. In addition, interruptions of other devices, DMA, or port conflicts may cause a few drivers to be abnormal and panic. The solution is to start in "Safe mode" and make appropriate adjustments in "control Panel" → "System" → "Equipment management". You can modify the registry for situations where an unexpected error occurs in the driver. Select "Run", type "REGEDIT", enter Registry Editor, and, through the "Find" function under the menu, locate and remove all "primary keys" and "key values" associated with the driver prefix string and reboot.

10, the memory capacity is not enough

The larger the memory capacity, the better, at least greater than the hard disk capacity of 0, 5%~1%. If this problem arises, it should be replaced with as large a memory as possible. Or add a new memory bar to the original memory.

11. Inferior Parts

A small number of unscrupulous businessmen in the assembly of compatible machines to customers, the use of poor quality of the motherboard, memory, and some even sell fake motherboards and the old CPU, memory, which will make the machine in operation is very unstable, the crash is inevitable. Therefore, users should have this vigilance when purchasing, can be a more familiar friend to help select, and can use some newer tools software testing computer, long time continuous test machine (such as 72 hours), as well as to strive for as long as possible warranty time.

　　Second, the software aspects of the problem

Computer crashes in addition to some of the above hardware problems, there are many are caused by software. Such as:

1. Virus infection

Virus is the scourge of computer operation, almost everyone is evil. Virus can make the computer productivity drop dramatically, causing frequent crashes, data loss, system crashes, and even damage to the motherboard, hard disk, CPU, and so on. Therefore, in the discovery of viruses we need anti-virus software such as KV3000, rising and other excellent anti-virus software to the computer for a comprehensive search virus, anti-virus, and to achieve timely upgrade anti-virus software.

2, CMOS set improper

This fault phenomenon is very common, such as hard disk parameter settings, mode settings, improper memory settings, etc., will cause the computer can not start. If the ECC-free memory is set to have ECC capabilities, it can cause a panic due to memory errors.

3, the system files mistakenly deleted

Because Windows startup requires files such as command, COM, Io, sys, Msdos, SYS, and so on, if the files are corrupted or mistakenly deleted, it does not even matter if the various hardware settings in the CMOS are correct. Workaround: Start the computer with the boot disk of the same version of the operating system, and then type "SYS C:" To transfer the system files again.

4, initialization of the file was damaged

Because Windows startup needs to read system, INI, Win, INI, and registry files, these two files will also be read if there are config, sys, Autoexec, and bat files. As long as there are error messages in these files, the panic may occur, especially the System, INI, Win, INI, User, DAT, System, dat four files are especially important.

5, dynamic link library file (, DLL) lost

It is also important to have a class of files in the Windows operating system that are dynamically linked library files with extensions, DLLs that are in nature shared class files, that is, one, DLL file may have multiple software that needs to be invoked at run time. If we delete an application, the software's anti-Setup program records the files it has installed and is prepared to delete them. At this time it is easy to delete the dynamic link library files will also be used by other software, if the missing link library files are more important core link files, Then the system will crash, or even crash. At this time, we can use the tool software such as "Super Bunny" to delete useless, DLL files, this will avoid accidental deletion.

6, hard disk left too little space or too much debris

Because some applications require large memory and hard disk space to run, if the hard disk space is too small, when these applications run a large amount of memory and the memory is not much, you need virtual memory, and virtual memory is provided by the hard disk, so the hard disk has enough space to meet the needs of virtual memory. Therefore, we should be equipped with a large hard disk, in addition, we must develop a regular hard drive, clean the hard disk garbage files good habits. This will not only avoid the lack of space on the hard disk or too much debris caused by the panic, but also the normal operation of the speed increase.

7, BIOS upgrade failed

The operator should back up the BIOS safekeeping, but if the computer system needs to upgrade the BIOS, it is best to determine if the BIOS version you are using is compatible with your PC before upgrading. If the BIOS upgrade is incorrect or an unexpected power outage occurs during the upgrade process, the computer system may fail to start. So be sure to figure out the BIOS model before you upgrade the BIOS. If you are using the BIOS upgrade tool to back up your current BIOS, you should copy the previous BIOS to a disk. Also see if the system supports BIOS recovery and how to recover.

8. Improper software upgrade

Most people may think that software upgrades are not problematic, in fact, some of the components that are shared during the upgrade are also upgraded, but when other programs may not support the upgraded component, a variety of problems can result in a panic. Therefore, when upgrading the software should also pay attention to the operation, first understand the characteristics of the upgrade software, performance and possible troubleshooting methods, and then upgrade.

9. Misuse of beta software

At present, many operating software is officially published in the first test version of the software, to check the reliability and stability of its software so that it can be properly improved when it is published, so the test software usually comes with bugs or is not stable enough in some way, and the beta software is not fully mature software. Therefore, when we are not very knowledgeable about the computer, it is best to use less software test version, so as to avoid the use of data loss after the program error, panic or the system can not start failure, to bring their own unnecessary trouble.

10, illegal uninstall software

Because the computer is running a lot of software now, people always like to download, install and uninstall software, this is not good. Not to put the software installation directory directly deleted, if directly deleted, the registry and Windows directory will have a lot of garbage, over time, the system will also become unstable and cause panic. Therefore, do not download and install software that is not necessarily needed.

11, the use of pirated software

Today, there are so many pirated software, almost all software has been pirated, because these pirated software may hide the virus, once executed, will automatically modify your system, so that the system in the operation of the panic. However, if the use of genuine software is not realistic, it can only be as little as possible with pirated software, especially the less commonly used software and some inexpensive software, you do not have to use pirated software.

12, the application of software deficiencies

This is common, such as running 16-bit applications that work well in DOS or Windows 3 and 1 in Win 98. Win98 is 32-bit, although it is known to be compatible, but there are many places that cannot be coordinated with 16-bit applications. There are also some cases, such as the normal use of the peripheral driver under the WIN95, when the operating system upgrade, there may be problems, so that the system crashes or does not start normally. In this case, you should find a new driver for your peripherals.

13. Too many programs to start

The startup of too many programs will make the system resources exhausted, and so that the data required by individual programs in memory or virtual memory can not find, there will be abnormal error, causing panic. Therefore, it is recommended that you start the program a little less.

14. Illegal operation

Illegally opening or releasing programs with illegal formatting or parameters can also cause the computer to crash. Note that to keep the correct format and related parameters in mind, do not randomly open and release unfamiliar programs.

15, Non-normal shutdown computer

Nowadays, almost all computers are equipped with wordows system, so we do not use the power button in the chassis directly when we shut down, otherwise it will cause the system file to be damaged or lost, causing the automatic startup or the running panic. For systems such as WINDOWS98/2000/NT, this is very important and, if serious, causes the system to crash. Therefore, the computer shutdown, unless the computer crashed and can not program shutdown, usually must use the computer on the "Shutdown System" button, to normal shutdown.

16, in-memory conflict

Sometimes the computer running a variety of software is normal, but it will suddenly panic, but the restart after the application is very normal. This is actually a false panic phenomenon. Many of the reasons for this are due to a conflict of memory resources for win 98. As you know, applications run in memory, and when you turn off the application, you can free up memory space. But some applications because of the design, even after the shutdown can not completely free memory, when the next software needs to use this memory address, there will be conflicts.

About the computer can not start how to do, the computer can not start the cause of the analysis and solutions for you to introduce here, according to the steps given above one by one to eliminate, generally can find cause computer startup problem. Only determine which part of the computer is not the normal start, we can be targeted to understand, judge, solve.
