3.Computer hunger refers to the need for hardware upgrades, and due to the increasingly advanced software features of today's software, many old computer hardware will appear in the computer situation if it does not meet the requirements.

Why does the computer screen go black after booting up, and how to solve it.

Is the monitor interface connected to the motherboard or the graphics card?

If you have disabled the integrated display, you can cancel it now.

Reinstall all the drivers for both the integrated graphics card and the discrete graphics card at once.

If the discrete graphics card is broken, the screen will be black and there is no display, so confirm whether the discrete graphics card is normal.

In fact, as long as the desktop is plugged in, the integrated display will be automatically disabled. It is not easy to plug in the independent graphics card on your computer, and you can only use the integrated graphics card, which means that your independent graphics card is either bad, or it is not plugged in firmly, or there is a problem with the graphics card slot of the motherboard, and this problem has to be checked one by one. If you want to use the integrated display is also simple, shut down, open the chassis, find the button battery on the motherboard, the battery is in the middle and lower part of the motherboard, near the independent display, the size is about the same as a dime coin, the edge of the battery slot has a buckle, break it to the side, the battery will automatically pop out, and then install the battery after half a minute (be careful not to install it backwards), which is equivalent to restoring the initial state of the motherboard BIOS, and your computer integrated display can be used again.

Did the landlord solve it? I now have this problem every day when I boot up for the first time, and it's normal after restarting, and it repeats every day.

Is there a "drip" sound and the brand's logo after turning it on?

1. The last correct configuration: Before booting and booting the operating system, we keep pressing the F8 key, select "Last correct configuration" and then press Enter.

2. Safe mode: If the "last correct configuration" does not solve the problem, press F8 when you boot up, enter the safe mode, use software such as 360 to repair the system files, and check for viruses.

3. If it can't be repaired, we can enter the safe mode for system restoration.

4. None of the above methods work, and it is recommended to do the following:

Desktop host: 1) Power off, open the chassis, plug in and unplug the memory, wipe the gold finger part with an eraser, and plug it back in (don't reverse it).

2) Plug and unplug the graphics card, wipe the gold finger part with an eraser, and re-insert it tightly (the buckle should be buckled).

3) Unplug the power cord, cut off the button cell battery of the motherboard, wait for three minutes, and then reinstall the motherboard.

Laptop:

Unplug the power cord, remove the battery, open the back cover of the memory, plug in and unplug the memory, wipe the gold finger part with an eraser, and plug it back in (don't reverse it).

Unplug the power cord, remove the battery, and press and hold the power button for 30 seconds without letting go.

If the fault persists, the system can only be reinstalled.

1: Power supply problem.

There is no display after powering on, the indicator light is not on, and the host has no sound. First see whether the display switch has been turned on, and then check the power supply, if the host power supply fan does not rotate, and the total power supply has output, then the main switching power supply. At this time, there are several possibilities, first of all, the power switch fails, and the power switch can be replaced;

The second is the internal fault of the switching power supply, although the power supply works but its output power can not meet the requirements, there is no other better way, it is recommended to replace the power supply or send it to a professional maintenance office.

The author once experienced that the sound of the computer when it was turned on was normal but not displayed, what happened? I couldn't find anything wrong after tossing for a long time. Then I found a place with a stable power supply and turned on and off the machine continuously and frequently.

Because the power supply will have a strong pulse at the moment of turning on and off, which stimulates the latching state of some parts of the power supply, the problem is simply solved.

2: The reset button is connected.

Some computers are equipped with a reset button, after a long time, the reset button of some computers does not pop up, and the microcomputer is in a state of restarting, so the screen is not displayed. In addition, dust accumulation and blockage of the reset key may lead to this situation, and the solution can be to clean the reset key with alcohol, etc., if it cannot be solved, you need to consider replacing the reset key.

3: CPU heat dissipation issues.

At present, the high-speed CPU generates a lot of heat, needs good heat dissipation, and many CPUs also have the ability to protect themselves, and will stop working when it reaches a certain temperature, the author encountered a computer, whenever it is turned on for about 2 hours, a black screen appears, and all peripherals cannot be used, including the power switch on the main chassis is also out of order, so I have to unplug the power socket to shut down, and then turn on the circuit, the machine cools down for about 5 6 minutes, and can last for nearly 1 hour after turning on. Open the case and then turn on the check,I found that the fan speed on the CPU slowed down significantly,Out of curiosity, I changed all the plug-ins on a good computer for up to 10 hours,The results are no problem,Finally, a few yuan for a new fan to get it。

4: Graphics card and memory problems.

Most of the cases of a black screen are here, and if there is an abnormal sound after booting, the first thing to consider is the graphics card and memory. Unplug it and observe it carefully, if there is no abnormal situation, clean up the next dust, wipe the gold finger, and then reinsert it, be sure to install the fixing screws, dust, looseness, poor contact, etc. are the main reasons for the black screen. Many friends who often disassemble and assemble the machine tend to ignore the installation of screws between the board and the chassis, but they do not know that these screws not only have the function of fixing the board, but also the role of grounding, and it is very unsafe not to install these screws.

Sometimes poor CPU contact can also cause a black screen, which is more common on some older computers with CPUs below 486.

Pressing F2 on your keyboard to continue should be fine.

The first reason is that the motherboard battery is dead, so try to change the battery.

The reason is that there is a problem with the BIOS settings, press F1 in the current interface to enter the BIOS settings interface. Load the default configuration and save it.

This is a screen saver.

Yes, you can set whether your program is Win7 or XP

Hello, your computer has the screen saver function turned on by default (it can be turned off).

First, right-click on the empty space on the desktop, Windows: Click on the Properties option. Win7 Click on the Personalization option.

Then you will find "Screensaver" and other similar windows, click into Close.

Hope it helps, hope o(o

It may be that some settings have not been adjusted.

Right-click on the desktop --Properties --Screensaver --Power--"Off Monitor" is set to never.

1. The most important out.

bai now has a black screen

There are many reasons for the black screen of the computer, and the common ones are:

Poor contact of the data line is displayed;

There is no power supply on the motherboard;

Poor contact back of the graphics card or; Answer.

Poor CPU contact and overheating;

Poor contact of memory modules;

poor power performance;

The machine is infected with the CIH virus and the BIOS is refreshed destructively.

Microsoft black screen, please patch.

Most of these problems are the relationship between the memory and the graphics card, loose or poor contact, just move it or use the eraser to wipe the gold finger of the interface

Remove the hardware acceleration in the browser and solve the problem.

Will the power indicator of the monitor be dimmed at the same time when the screen is black? If it's a problem with the system driver or graphics card, it will only cause the monitor's power indicator to change color and not dim. If the monitor backlight is soldered or aged, the power indicator should be normal when the screen is black.

When the screen is black, the power indicator is also dimmed at the same time, which is generally a problem with the high-voltage board of the display or the key board of the switch, and you can also try to plug in or replace the power cord of the monitor first to see if the problem is eliminated.

Remove the hardware acceleration in the browser and solve the problem.

Is it open the browser will appear, if you don't open it, it won't, or open multiple web pages or a certain web page will appear, if so, you press the above settings, I am after this problem, according to the above method to solve the problem.

The display panel driver circuit is broken, and it is recommended to replace it with a new one.
