There are many reasons why a computer can't be turned on. There are hardware and software reasons. Therefore, we must first understand whether the problem is caused by hardware or software, and it will help solve the problem. So why can't the computer be turned on? What if the computer can't open the machine? The following decoration house decoration network Xiaobian will bring you the reasons and solutions for the computer can not open the machine, for your reference only.
What if the computer can't open the machine?
The computer can't open the machine - the hardware reasons:
1, poor heat dissipation
Monitors, power supplies, and CPUs generate a lot of heat during operation, so it's important to maintain good ventilation. If the monitor overheats, it can cause color, image distortion, and even shorten the life of the monitor. Too long working hours can also cause the computer or computer to freeze due to poor heat dissipation from the power supply or display. The heat dissipation of the CPU is an important issue related to the stability of the computer operation, and it is also the "hardest hit area" in which the heat dissipation occurs, so it is necessary to ensure its good heat dissipation effect.
2, improperly moved
A large vibration during the movement of the computer often causes the internal components of the machine to loosen, resulting in poor contact and causing the computer to crash, so the computer should be protected from severe vibration when moving the computer. Usually, when the crash is found, you can also check whether the boards are loose. You can pull them out and plug them in again.
3, dust killer
Excessive accumulation of dust inside the machine can also cause a crash. For a circuit board, dust is no different from a time bomb. In addition, if the floppy disk head or the optical drive laser head is contaminated with excessive dust, it will cause reading and writing errors, and serious computer crashes. Therefore, computer room dust must be paid attention to frequently.
4, the device does not match
If the main frequency of the motherboard and the CPU frequency do not match, the old motherboard will set the FSB too high when overclocking, and may not guarantee the stability of the operation, resulting in frequent crashes. This is mainly due to the fact that the matching of the compatible parts of the compatible machine is not perfect. Therefore, when purchasing a compatible machine, please compare the insiders to help select the accessories.
5, software and hardware are not compatible
Three-dimensional software and some special software sometimes cannot be started or even installed on some microcomputers, and there may be problems in software and hardware compatibility.
6, memory module failure
Mainly due to loose memory, virtual solder or the quality of the memory chip itself. The memory module contact fault should be eliminated according to the specific situation, such as re-plugging. If there is a problem with the quality of the memory module, you need to replace the memory module to solve the problem.
7, hard drive failure
Mainly due to aging of the hard disk or bad sectors and bad sectors due to improper use. This makes it easy for the machine to crash when it is running. The fault on the hard disk must be repaired by special tool software and maintenance personnel. If the damage is serious, the hard disk can only be replaced. In addition, for motherboards that do not support UDMA 66/100, you should pay attention to the setting of the hard disk operation mode in CMOS.
8, CPU overclocking
Since CPU overclocking increases the operating frequency of the CPU, it may also make its performance unstable. The reason is that the speed of CPU accessing data in memory is faster than the speed of data exchange between memory and hard disk. Overclocking makes this contradiction more prominent, which aggravates the situation where the required data cannot be found in memory or virtual memory. This will cause an "abnormal error". The solution is simple, that is, to let the CPU return to the normal frequency.
9, hardware resource conflicts
This is due to a conflict between the settings of the sound card or the graphics card, causing an abnormal error. In addition, the interruption of other devices, DMA or port conflicts, may cause a few drivers to generate an exception, resulting in a crash. The solution is to start in "safe mode" and make appropriate adjustments in "Control Panel" → "System" → "Device Management". For situations where an exception error is generated in the driver, the registry can be modified. Select "Run", the key "REGEDIT", enter the registry editor, through the "Find" function under the menu, find and delete all the "primary keys" and "key values" associated with the driver prefix string, restart.
10, insufficient memory capacity
The larger the memory capacity, the better, at least 0, 5% to 1% of the hard disk capacity. If this happens, you should replace it with the largest possible memory. Or add a new memory stick to the original memory.
11, inferior parts
A small number of unscrupulous traders use poor quality motherboards, memory, and even sell counterfeit motherboards and old CPUs and memory when they assemble compatible machines for customers. This will make the machine unstable during operation and crashes. Inevitably. Therefore, users should be wary of this when buying a machine. Please ask a more familiar friend to help you choose, and you can use some newer tools to test the computer, test the machine for a long time (such as 72 hours), and try to be as long as possible. Warranty time, etc.
The computer can't open the machine - the software reasons:
1, viral infection
The virus is a big problem in computer operation, and almost everyone is evil. Viruses can drastically reduce computer productivity, causing frequent crashes, data loss, system crashes, and even damage to motherboards, hard drives, CPUs, and more. Therefore, in the discovery of viruses, we need to use anti-virus software such as KV3000, Rising and other excellent anti-virus software to comprehensively check the virus, anti-virus, and timely upgrade anti-virus software.
2, improper CMOS settings
This fault phenomenon is very common, such as hard disk parameter settings, mode settings, improper memory parameter settings, etc., will cause the computer to fail to start. If the ECC-free memory is set to have the ECC function, it will crash due to a memory error.
3, the accidental deletion of system files
Since Windows startup requires files such as Command, com, Io, sys, Msdos, and sys, if these files are corrupted or deleted by mistake, even if the various hardware settings in CMOS are correct, it will not help. Solution: Start the computer with the boot disk of the same version of the operating system, and then type "SYS C:" to re-transmit the system file.
4, the initialization file is destroyed
Since Windows startup needs to read System,ini, Win, ini and registry files, if there are Config, sys, Autoexec, and bat files, these two files will also be read. As long as there are error messages in these files, there may be a crash, especially the four files System, Ini, Win, ini, User, dat, System, and dat are especially important.
5, dynamic link library file (, DLL) is missing
There is also a class of files in the Windows operating system is also very important, this is the extension, DLL dynamic link library files, these files are of a shared class file in nature, that is, one, DLL files may be more The software needs to call it at runtime. If we delete an application, the anti-installer of the software will record the files it has installed and prepare to delete them one by one. At this time, it is easy to delete the dynamic link library files and also be used by others. In the case of software, if the missing link library file is a more important core link file, then the system will crash or even crash. At this time, we can use tool software such as "Super Rabbit" to delete the useless DLL files, which will avoid accidental deletion.
6, the hard disk has too little space or too much debris
Since some applications require large memory and hard disk space, if there is too little free space on the hard disk, when these applications need a lot of memory and there is not much memory on the machine, virtual memory is needed, and virtual memory is used. It is provided by the hard disk, so the hard disk needs to have enough free space to meet the virtual memory requirements. Therefore, when we are equipped with a computer, we must configure a larger hard disk. In addition, we must develop a good habit of regularly defragmenting the hard disk and removing junk files from the hard disk. This will not only avoid the crash caused by insufficient free space or debris, but also increase the speed of normal operation.
7, BIOS upgrade failed
The operator should back up the BIOS to prevent accidents, but if the computer system needs to upgrade the BIOS, it is best to determine if the BIOS version you are using matches 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 boot. So be sure to figure out the BIOS model before upgrading the BIOS. If you are using a BIOS upgrade tool that can back up the current BIOS, you should copy the previous BIOS to disk. Also see if the system supports BIOS recovery and know how to recover.
8, improper software upgrade
Most people may think that the software upgrade will not be a problem. In fact, some components shared in the upgrade process will also be upgraded, but when other programs may not support the upgraded components, various problems will occur. Lead to a crash. Therefore, you should pay attention to the operation when upgrading the software. First understand the features, performance and troubleshooting methods of the upgrade software, and then upgrade.
