Display Flash one flash black screen problem solving method

Solve the problem from the computer software:

1. May be the compatibility of software issues, in view of the user is playing the game will occur frequently, so focus on checking the game software and graphics driver is not compatible with the problem. The workaround is to update the graphics driver.

2. Because the user is a "recent" problem, you can see if you have recently installed what software caused the problem. The solution is to check, try to uninstall the newly installed software, which can be accomplished by software such as Shadow system. You can also use System restore points.
Monitor Flash a flash black screen how to do triple

from the hardware considerations :

1. It is possible that the connection between the host and the monitor is bad, you can remove the connector connector, for simple cleaning. Conditional, also can use anhydrous alcohol to clean up. Then plug it back in and see if it's back to normal.

2. It is also possible that too much dust in the chassis caused the system to be abnormally high temperature. The solution is to clean the inside of the chassis. If the problem is not completely resolved, only the video card or monitor damage, so that only professional maintenance.

The monitor screen displays 1-2 seconds after the black screen, reboot failure phenomenon is still, this fault and monitor internal power supply (power board), the possible fault location is:

1, high pressure plate;

2, backlight lamp, such as a lamp burning, or wiring virtual welding, oxidation, rust, or socket oxidation, rust;
3, AD driver board;
If the screen displayed after the black screen is visible under strong light (or strabismus), the fault belongs to the 1th or 2, otherwise it belongs to the 3rd article.
It is suggested that the landlord first distinguish the general parts of the fault and then proceed to overhaul or repair.

Supplemental: There are a number of reasons why the screen can wobble or flicker, try the following:

First, the display refresh rate is not set correctly

If the refresh rate setting is too low, it will cause the screen to wobble, check the blank area of the system desktop with the right mouse button, click the Properties command from the pop-up right-click menu, and go to the Properties Settings window of the monitor. Click the Settings tab in the window, click the "Advanced" button in the corresponding tab page that pops up, turn on the Advanced Properties Settings screen of the Monitor, and click the "Monitor" tab in it to see that the display's refresh rate is set to "60", which is why the monitor screen is constantly shaking. Set the new frequency to "75" and then click OK to return to the desktop.
In fact, monitor screen jitter is the main reason is the display of the refresh rate is less than 75Hz, at this time the screen will often appear jitter, flashing phenomenon, we simply adjust the refresh rate to more than 75Hz, then the screen jitter phenomenon will not appear again.

Second, the graphics card driver is not correct

Sometimes when we go into the computer's monitor refresh rate, we find that there is no refresh rate to choose from, because the driver of the previous video card is incorrect or too old. It's easy to get this problem on a computer that has an earlier purchase time at this point do not use the purchase of the computer with the CD-ROM driver, you can download the corresponding display card of the latest version of the driver, and then open the "System" Properties window, click the "Hardware" window of the Device Manager button to enter the system's device list interface. Right-click the display card option in the interface, click Properties from the pop-up right-click menu, click the Driver tab in the pop-up Graphics Properties Settings window, click the Update Driver button in the corresponding tab page, and then update the video driver to the latest version, as prompted by the wizard. Finally, the computer system restarted a bit, if the driver installation is appropriate, you will be the display refresh frequency options, and then set the refresh rate to more than 75Hz.

Third, the magnetic field interference caused the display jitter

Monitors are susceptible to strong or strong magnetic fields, and if the two methods described above still do not resolve the jitter problem, it should be suspected that the screen jitter is caused by a magnetic field or an electric field near the monitor. In order to remove all interference from the perimeter of the monitor, you can move the computer to a table around the empty, and then the power-on test, if the phenomenon of screen jitter disappears, then your computer where the original place has a strong electric field or strong magnetic field interference, please suspicious things (such as speakers of the subwoofer, magnetized cups, etc.) Take it away from the computer. Then turn off the monitor and reopen it a few times to achieve the purpose of degaussing (the current display has an automatic degaussing function when it is turned on).

Four, the display card contact bad

Open the chassis and pull the display card out of the slot. Then hand will show Kakin fingers of dust wiped clean, it is best to find soft hair brush, gently the graphics card surface of the dust all clear clean, and then use a clean eraser on the surface of the gold finger wiped a few, to clear the gold finger surface of the oxide layer, Finally, reseat the display card tightly into the motherboard slot and fasten it to the chassis shell with screws. Then the boot test, the general failure can be resolved.

The monitor and power failure can also cause the above failure to occur.

If you need to install the driver, it is recommended to install the Driver Wizard 2008, after installation, use its automatic update drive, it will automatically download and install the latest version of the driver, including, sound card, video card, network card, USB, etc., this is the drive of the confluence.

Some of the views of netizens

(1) The monitor is out of power or the monitor data cable is not in contact. In addition the computer used too long monitor power cord easily oxidized damage;
(2) The video card has bad contact or damage;
(3) bad CPU contact;
(4) bad memory access;
(5) machine infected with CIH virus, BIOS is destructive refresh;
(6) Check plug, If necessary, eraser, etc. to remove the oxide film on the finger;
(7) If the floppy drive has a floppy disk, many times will cause the computer to boot or restart, the computer will appear black screen, and can not enter the system. To avoid this type of situation, you can also cancel the floppy boot entry in the BIOS.  
  First check that the contact is good. You can check the video card and the display between the good contact between the video card and the motherboard I/O slot is good, if necessary, it can be removed, reinstall once, ensure that the installation in place, contact good.
  If contact is not a problem, it is a good idea to try a different monitor to make sure the monitor is fine.
  If the monitor is not a problem, see if the CPU fan is running, such as running, using a multimeter to measure the voltage output is normal for ±12v, ±15v, if not normal can be changed to a power supply to try.
  If the black screen still appears, remove the components installed in the computer, leaving only the CPU, video card, memory, you can limit the cause of the failure of the CPU, motherboard, memory among the three. In general, if the memory is faulty, should alarm sound. If a memory failure is eliminated, only the CPU and motherboard are available.
  for a normal CPU (should be compatible with the detected computer), power-on re-detection, such as still appear black screen, you can only change a motherboard, the problem should also appear on the motherboard. I hope I can help you.
