computer screen flashing black screen what to do

General new computer monitors rarely appear computer screen flashing or jitter, if the new monitor appears above the fault we first exclude the following possible:

First, the display refresh rate setting is correct

Check the method is: in our computer desktop blank area right---properties--settings-Advanced---Monitor the following figure:

You can 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. Part of the notebook computer only 60HZ This value, then do not need to set, and set too high prone to cause damage to the display, so we try to change, if not moved before, you can directly choose the default.

Second, check the video card driver is 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. Early purchase of the computer is prone to this problem, at this time do not use the purchase of the computer with the CD-ROM driver, you can check and install the latest version of the driver.

Third, whether there is interference around the computer

Observe whether there is a strong electric field or strong magnetic field interference around the computer monitor, magnetic field interference is very easy to cause the computer screen jitter or flicker, the elimination method is to place the computer in another open space to observe, you can go to another place to take a good computer to test the exclusion, as far as possible not to the display near large electrical products. Can also restart the computer monitor to see, the general current display in the open process has automatic degaussing function.

Quad, monitor hardware problems or power problems

The above situation encountered less, most of the hardware problems encountered, such as the monitor and host connected to the data line, and so on, we can be replaced by the elimination of the method to solve, in addition to the monitor power only focus on the object, in the computer screen jitter encountered and computer screen flashing fault, One of the computer screen flashing encountered the most is the monitor power problem, there are many is the monitor aging, monitor failure. Monitor Jitter In addition to the magnetic field or electric field interference, the most encountered is the monitor aging fault, the solution is to take to professional maintenance point repair. General new display can be taken to warranty or replacement, the new monitor due to hardware problems caused by the general very rare.

Introduced here about computer screen flashing and computer screen jitter Troubleshooting method is basically the method described above, sometimes computer virus damage can cause you to open some software or browse the Web site similar situation, and some of the Web page will also put some web effects to achieve the computer screen jitter and flicker effect, Finally remind everyone if it is really difficult to eliminate, can be a computer dead horse when the horse medical, directly reinstall the system, if the problem is still most of the hardware failure, need to take to professional repair shop to solve.
