Computer black screen is how the computer black screen how to solve

Computer black screen is what's going on, computer black screen How to solve, the computer black screen is our daily use of a common phenomenon, often displayed in the monitor after the boot no image display, or in use, the monitor suddenly black screen, there are some computer normal startup, but to a certain step suddenly and black screen. Also because the black screen can not see any hint information, also can not carry out the corresponding operation, generally more headaches. Generally speaking, black screen is divided into software problems and hardware problems, as well as user habits. Then encounter the computer black screen How to do? The following is the author to introduce the common black screen phenomenon, as well as the solution of the method.

Computer black screen is going on, computer black screen How to solve,

First, software problems

1, operating system settings for reasons such as screen protection, power management.

2, in addition to the display card driver is incompatible, etc. will also cause a computer black screen phenomenon, this situation, just reinstall the driver and debug the system can be resolved.

3, of course, there may be a virus caused by black screen, such as the power-on display information, when the desktop suddenly black screen, then the system may be damaged by viruses, this situation can be used to redo the system or restore solution.

4, software conflicts, because of the universal expansion of the PC, make PC very vitality, there are tens of thousands of companies compiled a variety of software, may appear such a situation, put them together, address calls conflict and cause the crash black screen, the solution is also very simple, that is just installed the software uninstall off.

Second, the hardware problem

1, first of all have to mention some very common but may be overlooked situation, such as the monitor power plug loose, no power, or VGA interface bad, or monitor switch some glitches, did not press. If all is confirmed, we will determine the hardware failure.

2, heat dissipation problem: After the computer boot, normal access to the system, running for a period of time (or the normal use of a short period of time), suddenly black screen, this situation is likely to be caused by heat dissipation, the normal temperature of 30-50 degrees, in general, any part of more than 50 degrees will cause the motherboard protection, So the computer shuts down automatically and restarts. The solution is also simple, add a heatsink, or replace the heatsink.

3, graphics card or display problem: The two devices in the computer boot black screen failure in a small proportion, usually using substitution method, for a display to use, such as normal use, indicating that the original monitor is broken. If the change of a monitor or black screen, consider host problems, usually such as easy to think of the graphics card problem, the same can be replaced by the video card, such as the normal display, said the obvious card failure.

4, the Power problem: Everyone in the machine is always in the CPU, memory up and down, the power is always buckle, the power supply is for all components to provide power, if it has trouble, the host will issue a "drip" a sound alarm. And the monitor is not bright, occasionally will not say a word, after the investigation is also a power problem.

5, motherboard problem: The main is the CMOS Setup error, set the first initialization of the video card for PCI or onboard AGP video card, the monitor is not connected to the corresponding position, the result of the normal start of the host, but the display is not lit.
