Security monitoring summary of the old driver's summary

1. What is the cause of jitter in the monitor display?

This situation is generally caused by the display refresh rate setting is too low, enter the "Display Properties" click "Settings", select "Advanced", then select "Monitor", the new frequency is adjusted to 75HZ, after the exit can be resolved This problem.

2. Why does the monitor appear to have a screen saver or a black screen when the monitor is turned on for a period of time?

This situation is caused by not having to cancel the screen saver or improper power management settings. The solution is to exit from the monitoring system to the WINDOWS operating system interface, right-click on the interface, select "Properties", select the screen protection in the tab appears, select (none) to cancel the screen saver. Then click on the settings button in the lower right corner, select "Always open" in the power scheme, the system waits to select "never", close the monitor and select "never", "close the hard disk" where "never", and finally click "OK" can be.

3, digital hard disk recorder image display only the image does not operate the button or the screen is not full of the entire screen What is the reason?

Under normal circumstances, the display resolution setting does not meet the requirements, the desktop resolution is set to 1024*768, and the small font can be changed to a large font.

4. How should the HD video host be partitioned?

System main hard disk:

1) Create primary partition C: (2 to 3GB) (OS + application software.)

2) Create an extended partition (100% of the remaining hard disk)

3) create a logical partition in the extended partition D: (usually allocated about 4GB, mainly stored application backup and some video data)

4) Create logical partition E under the extended partition: (remaining hard disk space) (video data)

5. Why does the monitor have a screen saver or a black screen when the monitor is turned on for a while?

After exiting to the operating system interface, right-click on the interface, select Properties, select Screen Saver in the tab that appears, and select (none) to deactivate the screen saver.

6, why no boot?

Make sure the chassis and monitor are properly connected and the power is connected and turned on. In the process of transportation and moving, the body may loosen the internal card accessories. It is best to open the chassis before starting the machine and confirm that the components are plugged in and then turned on. If the main board self-check is abnormal during startup (normally, the keyboard indicator LED flashes once and the host buzzer emits a “beep” sound), please turn off the power and check whether the CPU board and the video card are fully inserted, and remove the board. Plug in again. If you press the power switch and the CPU fan does not turn and the panel power indicator does not light, check that the power supply is connected properly.

7. What kind of operating system can the hard disk video card work under?

Hard disk video card can be used above Windows/2000, support PNP function.

8. Why does a system crash occur and how do I recover?

If the improper setting of windows or some other software failure causes the system to work abnormally, system crashes will occur. The following methods can be used to recover the system:

First: Windows registry method repair system. For example, if you do not open the monitor or the monitor is connected improperly when you start the system for a certain time, the system cannot be normally accessed when the system restarts. You can use the following steps to repair it.

Restart, hold down the F8 key during startup, select "Command Prompt only" in the boot mode selection menu, and after booting, type the following command line: scanreg/restore Select the date of the most recent system work to restore.

Second: When using the recovery registry can not solve the problem, you can use Ghost to restore the system, provided that you have used the Ghost backup system. Use method is to start (start with hard disk or start with WIN98 boot disk) to DOS state, run Ghost.exe, follow the prompts to complete the system recovery

9. What should I do if there is no image display?

One reason: Due to incompatibility of the graphics card, the Direct Draw test can be used. If the test passes, this is not the reason.

Cause two: The PCI interface is not in good contact. You can switch to a PCI slot test.

Cause three: If the card is damaged, you can consider changing the card test.

10. Audio and video card driver installation instructions.

The driver for the video card cannot be installed in more than one. Only check the complete number of drivers in safe mode.

Example: You have 8 cards plugged into the motherboard. You can only install 8 drivers. You should check the number of audio and video card drivers in 'safe mode'. If the video card driver is more than the number of installed video cards, the system sometimes does not work properly.

Note: Four-way real-time cards are equivalent to four separate cards, four drivers need to be installed, and the other audio and video cards install one driver per card! If you find this phenomenon, you should put all video cards in 'safe mode' Remove all the drivers (including other duplicate devices of the system), and then restart the computer.
