Analysis of why hard disk recorders often crash, what is the reason?
Speaking of hard disk recorders should be very familiar with it, at the same time, due to a variety of built-in DVR 209M, PTZ camera control, alarm control, network transmission and other powerful features, also has a vast market in the security market, it is understood, do the hard disk recorder manufacturers in the security industry also has a lot of, for example, Dahua Group of hard disk recorders, hard disk recorders, Hikvision DVR and so on, these products are very good, the quality is very good, but the good things are when a fault so I find some information on DVR crash and analysis of how to deal with the nine key information on the Internet, for your reference at the same time, also hope to bring some convenience to everyone.
First, the power supply is obsolete
To buy a new computer upgrades, such as installation of the high speed CD-ROM, because of the high speed, the power consumption is large, the increased power load will also appear to crash or restart the phenomenon. The original power does not take into account the current hard disk, graphics and high speed CD-ROM such as power consumption, so the power output is not too high, plus some brand-name power itself "shrink", cannot provide enough electricity, when more devices in the system, power consumption becomes large, poor power output voltage will be drastically decreased, eventually lead to system instability, automatic restart. In addition, the power supply socket contact is bad, the voltage fluctuation is too big, and possibly causes the hard disk and so on equipment damage. Can replace a high-power high-quality power supply, so that your computer can provide the most secure protection.
Two, suffered blackouts
The monitor, host, speaker, etc. will be forced to close in a flash. The presentation of data is written will be lost, such as disk read and write operations, and may produce bad sectors. The instantaneous voltage fluctuations of power outages also impact chips, circuits, resistors, etc. of computer hardware. In order to avoid accidents, when installing a computer, it is best to choose a brand power supply, so as to minimize the adverse effects of voltage fluctuations on the hardware from the power supply. After power cuts, turn off all the power, in case the next call, the monitor and the ATx power will be activated at the same time, which will cause bad damage to the hardware. When you use word to edit manuscripts, the use of word automatic save function, if the power moment happens to be in the operation of the disk, the next boot disk do not skip detection at startup, to detect no bad sectors. Once the bad sectors, the use of Norton, pqmagic and other tools to repair or shield bad sectors. In addition, such as an economic license, a UPS is selected to provide power off protection for the computer.
Three, automatic shutdown
Today, the mainstream motherboard for CPU temperature monitoring function, once the CPU temperature is too high, more than the motherboard BIOS set temperature, the motherboard will automatically cut off the power supply to protect related hardware. On the other hand, power management and virus software in the system can also cause automatic shutdown. If the sudden shutdown occurs frequently, make sure that the heat dissipation of the CPU is normal. Boot box to see whether the fan blade is working properly, and then enter the BIOS option to see the fan speed and CPU operating temperature. If it is a fan problem, dust removal or maintenance of the fan or replacement of a better quality fan. If the power is aging or damaged, you can confirm the power by replacing the power supply and replace it with a new one in case it burns down the hardware. Of course, it may also be poisoning, into the system, from the installation of CD-ROM to cover the installation of power management, and then thoroughly kill the virus. At the same time, always update antivirus software virus library, use pirated disk less, do not download the unknown mail attachments.
Four, system crash
Desktop locked or blue screen, the mouse can not move, and even when the alt+ctrl+del is not even hot. In addition to the system itself and bug compatibility problems among different software, can also be run at the same time too many programs leading to process blocking, causing crashes. When there is true or false, press the NumLock button, indicator light changes for fake crash. When you can press Alt + Ctrl + Del at the same time, select the name of the program in the list of tasks that appear, then mark the missing item, and click finish task. Yes, it was solved by cold start. For the blue screen, press the reset button after the ESC key is invalid.
Five, system failure
Can not enter the system, start the screen still, or show: the, disk, is, error and so on, there are e text prompts a lot of phenomena. The more common reason is that the system files have been modified, broken, or loaded with an abnormal command line. In addition, the hard disk fault is also one of the reasons. First try whether you can go into safe mode, press the F8 button by booting, and select the third item in the Startup menu: safe model (safe mode). After you have entered the safe mode, you can find the fault through the device manager and the system file checker"! The number can be checked to determine whether the Del or the setting is interrupted. You can also reinstall the driver, and the system file is damaged and can be restored from the installation file (you can copy the windows installation disk in your hard disk). If can enter the safe mode, by starting with CD-ROM or floppy disk boot to DOS in DOS, the first anti-virus and system files in C dir check is complete, if necessary by sys c: through the system disk, restore the file system related to the basic. If C is not found within the file, only to reinstall the system.
Six, hardware resource conflict
If the motherboard does not match the frequency and CPU frequency, when the old motherboard overclocking FSB too high, may not
