DVR crashes In addition to some hardware problems, many are caused by software. Such as:
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, cmos is not set properly
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 memory without the ecc function is set to have the ecc function, this will cause a crash due to a memory error.
3, the initialization file is destroyed
Because windows startup needs to read system, ini, win, ini and registry files, if there are config, sys, autoexec, 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.
4, 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.
5, 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.
6, bios upgrade failed
Operators should back up bios to prevent accidents, but if the computer system needs to upgrade 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, the computer system may fail to start. So before upgrading bios, you must figure out the bios model. If you are using the bios upgrade tool to back up your current bios, you should copy the previous bios to disk. Also see if the system supports bios recovery and know how to recover.
7, 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.
8, abuse of the beta software
There are a lot of operating software on the market for some beta software to check the reliability and stability of its software operation, so that it can be properly improved when it is officially published. Therefore, the test software usually has some bugs or is not stable enough in some aspects. The software version is not considered to be fully mature software. Therefore, when we are not very good at computer, it is best to use the test version of the software to avoid unnecessary errors such as program errors, crashes, or system failures after use. .
9, illegal uninstall software
Since there are so many softwares running on computers today, people always like to download, install and uninstall software frequently, which is not good. Do not delete the directory where the software is installed directly. If you delete it directly, there will be a lot of garbage in the registry and the windows directory. Over time, the system will become unstable and cause a crash. Therefore, do not download and install software that is not necessarily needed.
10. Use pirated software
Nowadays, there are so many pirated softwares. Almost all softwares are pirated. Because these pirated softwares may hide viruses, once they are executed, your system will be modified automatically, causing the system to crash during operation. But if you use genuine software, I am afraid it is not realistic, so you can only use pirated software as little as possible, especially if you don't use software and some low-priced software, you don't have to use pirated software.
11, the defect of the application software
This situation is common, such as running 16-bit applications that run well in dos or windows 3, 1 in win 98. Win 98 is 32-bit, and although it is said to be compatible, there are many places that cannot be coordinated with 16-bit applications.
12, too many programs to start
If too many programs are started, the system resources will be exhausted, and the data required by the individual programs will not be found in the memory or virtual memory, and an abnormal error will occur, causing a crash. Therefore, it is recommended to start the program a little less.
13. Illegal operation
Unlawfully opening or releasing the program with an illegal format or parameter can also cause the computer to freeze. Please note that keep in mind the correct format and related parameters, do not open and release unfamiliar programs at will.
14, abnormally shut down the computer
Most of the PC hard disk recorders are equipped with windows system. Therefore, we should not use the power button in the chassis directly when shutting down. Otherwise, the system files will be damaged or lost, causing automatic startup or crash during operation. For Windows 98/2000/nt and other systems, this is very important. If it is serious, it will cause the system to crash. Therefore, for the PC-type hard disk recorder to shut down, unless the PC-type hard disk recorder crashes and cannot be shut down, the "shut down system" button on the computer must be used to shut down normally.
15, memory conflicts
Sometimes the PC-type hard disk recorder is normal when running various software, but it suddenly crashes inexplicably, but it is normal to run these applications after restarting. This is actually a phenomenon of false death. The reason for the occurrence is mostly due to the memory resource conflict of win 98. As you know, the application software runs in memory, and the memory space is freed after the application is closed. However, due to design reasons, some applications cannot completely release the memory even after being turned off. When the next software needs to use this memory address, a collision will cause a crash.
The Cnc Cutting Machine has the characteristics of fast cutting speed and small slit in the cutting process, which may lead to limited actual cutting speed, excessive kerf and uneven cutting surface, and eliminate the mechanical failure of the plasma CNC Cutting Machine. Failure to properly set the plasma CNC cutter related parameters during operation will also affect the actual cutting effect.
The hub processing parts of large ships are concentrated in the base of high-power diesel engine, frame, cylinder block, cylinder head, piston rod, crosshead, connecting rod, crankshaft, and gearbox drive shaft, rudder shaft and propeller, etc. The material is special alloy steel, which is generally processed in small batches and requires a processing yield of 100%. The hinged parts have the characteristics of large weight, complicated shape, high precision and large processing difficulty. Large-scale ship pivot processing requires high-power, high-reliability and multi-axis heavy-duty, ultra-heavy CNC cutting machines.
