Hello everyone, Lin Fei to answer the above questions, notebook black screen is on how to restore, notebook black screen many people do not know, now let's take a look!

The black screen of computer boot is a very common computer failure. Of course, there is a special case-the computer boot black screen! That is, the computer starts normally, but a black screen appears after entering the system. The author has also encountered similar problems several times. For example, once the new system was incompatible with the possible driver, the system and the driver went black as soon as they entered the system, and then the problem was solved without installing the driver that came with the system. Of course, there are a lot of questions. The author summarizes the tutorial on how to solve the black screen after the notebook is turned on.

What's the matter with the black screen after the computer is turned on? what should I do when I enter the system?

First of all, check whether the refresh rate of the monitor is set too high. After entering safe mode, right-click the desktop and select Properties. In the window that opens, select the Settings tab, click the Advanced button, select the Monitor tab, and set the screen refresh rate to low. If the problem cannot be resolved, consider whether there is a problem with the video card driver, uninstall and reinstall the video card driver in safe mode. In addition, virus infection in the system may also cause this phenomenon. It is recommended that you clean the system in safe mode. What if the audio service is not running?

How to solve the notebook boot black screen tutorial.

First, check that the computer components are securely plugged in.

First check whether the display cable is firmly plugged into the host interface, and then check whether the contact between the video card and the motherboard Iram O slot is good. If necessary, remove the video card and reinsert it to make sure it is in place and in good contact.

Second, confirm that the monitor is damaged.

If the monitor and video card are securely installed, try another known good monitor. If the screen is no longer dark, the reason is that the monitor may be damaged.

Third, confirm whether there is a problem with the fan.

If the monitor is not damaged, further check to see if the CPU fan is running. For example, you can use a multimeter to measure whether the normal voltage output is 12V or 15V. If it's not normal, you can try another power supply.

Fourth, check CPU, graphics card, memory.

If the black screen still appears, remove all components except the CPU, video card, and memory module, and then power on the computer. If there is a memory failure, there should be an alarm. If it is not a memory problem, change to a normal CPU and restart the test. If there is still a black screen, only one motherboard can be replaced, and the problem should also appear on the motherboard.

In addition to the black screen phenomenon caused by hardware reasons, there are three "soft" reasons that may lead to "black screen".

First, the hardware acceleration setting is too high.

Hardware acceleration can make software that has to deal with a large number of graphics run more smoothly, but if the computer hardware acceleration setting is too high, it may lead to "black screen" phenomenon. To solve the "black screen" problem, please try to reduce hardware acceleration.

1. Click the Windows start menu, click Control Panel, and then double-click the display.

two。 Select the troubleshooting tab, and under hardware acceleration, gradually drag the slider from all to close to none.

3. Click the OK button.

Second, disable 3D acceleration or upgrade the video card driver.

If Windows is already configured with 3D acceleration, but the video card does not support this feature, a "black screen" failure may occur when running games or multimedia programs.

1. Click start, then click run, then type dxdiag in the Open box, and press enter.

two。 Select the display tab and click the Test Direct 3D button under DirectX Features to get the correct Direct 3D functionality.

3. If there is no rotating cube on the screen, the video card does not support 3D acceleration. At this point, click the "disable" button after "Direct 3D acceleration" to disable this feature.

If your graphics card does not support 3D acceleration, in addition to disabling this feature, you can also contact the graphics card manufacturer to update the driver to support DirectX 3D acceleration.

Third, the video card driver is not compatible with the video card.

The DirectX installer may incorrectly detect the video card and install drivers that do not drive properly. Make sure you are using the correct video driver.

1. Click start, click Control Panel, and then double-click the system.

two。 Select the hardware tab, click the device Manager button, then click the symbol before display Card or display Adapter, right-click the display adapter below it, and then click the Properties button.

3. Select the drivers tab, and then click the driver details button to display the video card driver you are using. If you are using a driver that is not compatible with the video card, click driver

First, poor heat dissipation: the display, power supply and CPU generate a lot of heat at work, so it is very important to maintain good ventilation. If the display is overheated, it will lead to color, image distortion and even shorten the life of the display. Too long working hours can also lead to poor heat dissipation of the power supply or monitor, resulting in a computer crash. The heat dissipation of CPU is an important problem related to the stability of computer operation, and it is also the "worst-hit area" of heat dissipation failure.

Second, improper movement: the large vibration in the process of moving the computer will often make the internal devices of the machine loose, resulting in poor contact and causing the computer to crash, so violent vibration should be avoided when moving the computer.

Third, dust killer: too much dust in the machine will also cause crash. Such as floppy drive head or optical drive laser head contaminated with too much dust, will lead to reading and writing errors, serious will cause the computer to crash.

Fourth, equipment mismatch: if the motherboard main frequency and CPU main frequency do not match, the old motherboard overclocking will set the external frequency too high, it may not be able to ensure the stability of operation, resulting in frequent crashes.

Fifth, software and hardware are not compatible: 3D software and some special software may not be able to start or even install normally on some microcomputers, and there may be problems in software and hardware compatibility.

6. memory bar failure: it is mainly caused by loose memory bar, virtual welding or the quality of the memory chip itself. The contact problem of the memory bar should be eliminated according to the specific situation. If there is a problem with the quality of the memory bar, the memory needs to be replaced to solve the problem. Boot only hear "tick, tick" single sound long sound, probably is the memory problem, try another slot, still can not, the memory may be broken.

Seventh, hard disk failure: mainly due to the aging of the hard disk or due to improper use caused by bad roads, bad sectors. In this way, the machine is prone to crash when it is running. Special tool software can be used for troubleshooting, and if the damage is serious, the hard disk can only be replaced. In addition, for motherboards that do not support UDMA 66amp 100, attention should be paid to the setting of the running mode of the hard drive in CMOS.

CPU overclocking: overclocking increases the working frequency of CPU, at the same time, it may also make its performance unstable. The reason is that the speed of CPU accessing data in memory is faster than that of exchanging data between memory and hard disk. Overclocking makes this contradiction more prominent and aggravates the situation that the required data can not be found in memory or virtual memory, so there will be "abnormal errors". The solution, of course, is to get CPU back to its normal frequency. Overclocking exceeds the fire, sometimes the monitor is not lit, sometimes it crashes after entering the system, and in serious cases, the CPU will be burned out.

9. Hardware resource conflict: it is due to the setting conflict of sound card or display card, which causes abnormal error. In addition, the interruption of other devices, DMA or port conflicts may cause a few drivers to produce exceptions, resulting in a panic. The solution is to start in "safe mode" and make appropriate adjustments in the "control panel" → system "→" equipment management. For cases where an exception error occurs in the driver, you can modify the registry. Select "run", type "Regedit", enter the registry editor, find and delete all "primary keys" and "key values" related to the driver prefix string through the "find" function under the menu, and restart.

10. The memory capacity is not enough: the larger the memory capacity, the better, which should not be less than 0.51% of the hard disk capacity. If there is a problem in this respect, you should replace it with a memory stick with as much capacity as possible.

11. Inferior parts and components: a small number of unscrupulous businessmen use inferior quality boards and memory when assembling compatible machines for their customers, and some even sell fake motherboards and Remark CPU and memory. Such machines are very unstable when running, and a crash is inevitable. Therefore, users should be vigilant when purchasing the machine, and can use some newer tool software to test the computer, test the machine continuously for a long time (such as 72 hours), and strive for the warranty time as long as possible.

12, the board, card contact is bad, loose, or the slot on the board is broken, or simply display card, memory and other accessories are broken, resulting in the display is not bright.

Thirteen, the voltage fluctuation is too large, causing the current on the board and card to be large or small, sometimes damaging the hardware. Therefore, it is very important to choose a power supply that can protect the overvoltage, or add a voltage regulator.

Fourteen, printers, burners, scanners and other peripherals have broken down, but plug-and-play technology causes the system to detect these devices at startup.

If the mainframe is running normally, there is also the sound of the hard disk running, but the monitor is not bright, it may be that the monitor is broken, or the signal line of the monitor is not good or bad, or the power supply of the monitor may not be plugged in.

Sixteen, the motherboard capacitance. Sometimes our other hardware is fine, but no problems are found, but everywhere we turn on for a while and then crash, motionless, but this is an unlimited time. You may guess it is the system problem, but this is not, this is the motherboard capacitance is broken.

The general inspection methods for the crash fault of the black screen of the system are as follows:

① eliminates "fake" black screen

Check whether the monitor is plugged in, whether the power switch has been turned on, whether the data connection between the monitor and the display card on the host computer is well connected, and whether the connection plug is loose, to see if the black screen is caused by these factors.

In addition, you should move the mouse or press the keyboard to see if the screen is back to normal. Because the black screen may also be a fake panic caused by setting the energy saving mode (which can be viewed and modified in the BIOS settings).

② is in black screen at the same time whether the other parts of the system are working properly, such as whether the soft / hard drive self-test is passed at startup, whether the keyboard keys react, etc. Through the exchange method, a good monitor can be connected to the host computer to test, if only the display screen is black and the other parts are normal, then there is something wrong with the display, which is still a false death phenomenon.

The ③ black screen occurs during the system post, see step 6.

The ④ black screen occurs during the installation of the display driver or the setting of the display mode, which obviously chooses a mode that the display system cannot support, so a more basic display mode should be chosen. For example: after setting the display mode under Windows, you should run the SETUP.EXE program in the Windows directory under DOS to choose the standard VGA display mode.

⑤ check whether the contact between the display card and the motherboard I _ ram O slot is normal and reliable, and if necessary, you can try to insert a new I _ hand O slot into the display card.

⑥ has been confirmed to have good performance of the same type of display card inserted into the host to restart, if the black screen crash phenomenon is eliminated is the problem of the display card.

⑦ to replace a confirmed good performance of other models of the display card into the host to restart, if the black screen freeze phenomenon is eliminated, the display card is not compatible with the motherboard, you can consider replacing the display card or motherboard.

⑧ checks whether the core components of the system are set incorrectly, such as the frequency of the CPU, the read and write time of the memory, the refresh mode of the CACHE, the bus rate of the motherboard, etc., all of which may lead to the black screen panic.

⑨ checks whether the internal parts of the host are connected correctly. Some special wiring errors will cause the black screen to crash.
