The computer was turned on for a few minutes, and suddenly the screen went black

There is an error dumping message, which means that it is a software problem! There is a high probability of driver and program errors, in fact, you can use Microsoft's error analysis software to open C: Windows Minidump

These two files will analyze which software or driver error is causing it!

The computer starts and sails normally, but the black screen does not show the desktop because:

1.It may be that there is a problem with the computer's system, such as incompatible installed patches, incompatible software, incompatible drivers, and the lack of Sodanyan files in the system itself.

2.It may be that the graphics card and memory module in the computer are not in good contact, resulting in a black screen on the computer, so that it cannot enter the desktop. Solution: Try removing and wiping the graphics card or memory module from your computer, and then reinstall it after the World Bank.

3.It may be that the hardware related to the computer screen is damaged, which directly causes the computer to go black, so that the desktop system cannot be displayed.

The details are as follows.

If the indicator is not on, it means that the monitor is not powered on or the power switch is not turned on. Check for loose or damaged graphics cards and reinsert devices on the motherboard, such as graphics cards, memory modules, etc., and replace the COMS battery if necessary. If there is a problem with the connection between the computer and the monitor, check whether there is a problem with the cable, and if the interface is loose, reconnect it and try again.

If the liquid breaks or breaks, replace a connecting cable.

Sleep caused by a black screen, press the ESC button or the computer shutdown power button to resume. If the black screen is caused by a software failure, force restart to solve it, and press the Ctrl+Alt+Delete keys to restart the computer. Black screen caused by hardware failure, replace hardware or repair hardware and reinstall it.

GRUB when the computer is booted is generally in the Win7 operating system with one-click restore software installed, which means that the main boot file is lost or damaged. Fix with dos command. Enter ** on the screen behind the grub command prompt.

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

First of all,The display generally doesn't love to have problems,The problem also appears in the host,I hope it is caused by loose components,Mainly the memory and graphics card are loose,Open the case cover,Unplug the memory and graphics card,Clean the dust in the chassis,Then insert the memory and graphics card back,(Note:Insert the memory remember not to plug in the reverse,Burn the memory and the motherboard memory slot) and then boot to see if it's good,If it's still the same as before,Then you can't solve this problem yourself,You can only report for repair。

It should be a problem with the graphics card, see if the fan of the graphics card turns.

You unplug the memory card and wipe it and try it.

The reasons and how to deal with the blue screen that cause your computer to always be blue are as follows:

The first type: If your computer often has a blue screen, whether you have not reinstalled the system, or later reinstalled the system, or there is a blue screen, it means that it is a problem with your hardware, and the direct hardware is a memory module or graphics card. Generally, this is due to the blue screen phenomenon caused by the oxidation of the gold finger of the memory or graphics card or poor contact with the slot.

The solution is: you can turn off the power first, open the compartment, dial out the memory, use the eraser against the part of the gold finger (that is, where there is a copper sheet,) and wipe it back and forth a few times, and then change a memory slot to plug it back, it's OK, if you do this or a blue screen, you have to check the graphics card, indicating that it is a problem with the graphics card, and it is OK to do it with the same method as above. Generally, 80% of computers can solve the problem.

The second type: is the hard disk has a bad sector, when the computer reads the bad sector, it is stuck, the background is still running, the CPU occupancy is immediately very high, and then the blue screen, processing method: under normal circumstances, it is repaired with HDD, if it can't be repaired, which can only change the hard disk.

The third situation: that is, the video memory and the graphics card's video memory chips appear virtual soldering, and the blue screen will continue to appear, the method is to add solder to the video memory

The fourth is: the computer is poisoned, causing the memory to enter the virus, destroying the operating system, causing the system to be unable to boot, and the blue screen is all the time, where to reinstall the system, or one-click restore.

Fifth: It is because of illegal shutdown, such as power failure, forced shutdown, or sudden crash, after turning on, it will be self-checked, it is also a blue screen, in the countdown, under normal circumstances, let it read it by itself, it is OK, it may waste a little time, but it must read it by itself, because this is the process of checking the disk by the hard disk, generally read it for the first time, and it will not appear next time. Don't stop with ESC, you can't have a blue screen next time, start again.

If you want to self-test every day, you have to start running ---chkntfs after entering the system

t:0", the general problem is solved.

Before doing the above, it is best to restore the BIOS of the motherboard to the factory value, or you can discharge the motherboard battery, that is, remove the battery, wait for 20 seconds and then install it back, or connect the jumper to two or three, which is conducive to eliminating strange phenomena caused by the disorder of the motherboard BIOS.

1. You can directly use the "Ctrl + Shift + Esc" shortcut key to open the Task Manager program directly;

2. After the task manager pops up, find "Processes" in the "Processes" tab;

3. Check the "End Process" button below to close the explorer;

4. Then click "File" in the upper left corner to open the menu, and select "New Task (Run)";

5. After that, the "New New Task" window will pop up, enter the name of the process you just closed", and click OK.

Memory reason:

Try the following.

1. Remove the memory and wipe the gold finger of the memory with a clean eraser (wipe it outward in the direction of the gold finger) 2. Insert the memory into another slot. (If there are multiple pieces of memory, you can plug them in one by one and try to boot them first.) Graphics card reason:

1. For a discrete graphics card, refer to memory.

1. Remove the graphics card and wipe the gold finger with a clean eraser (wipe it outward along the direction of the gold finger) Network card Reason:

If it is an independent network card (generally computers are integrated now), you can remove the network card first and try to turn it on. If it is an integrated network card, you can try to turn off the network card in the motherboard BIOS and then turn it on.

Motherboard or CPU reason: This is troublesome, to find accessories to try on, I hope it will not be this reason, after all, this reason does not appear much. The above situation is specifically for the situation that the computer cannot be turned on and the display does not light up.

Of course, if the situation is described and there is no detection sound, then there is a very high possibility that there is a problem with the memory, and the memory needs to be replaced.

If there is a problem with the monitor, you must first confirm whether the monitor is broken, and you can turn on the power of the monitor separately to see if it is normal. (If conditions permit, connect the monitor to another host and try) If it doesn't work, then the monitor is broken, change the monitor.

2. Problems with the connection cable of the monitor.

The chance of damage to the monitor cable is very small, and you can check whether the cable is loose or in poor contact.

None of the questions asked.

Memory module problems often occur, including: the memory module is dirty or the gold finger is oxidized, you can use the eraser to wipe the memory stick, especially the gold finger part, the gold finger on both sides should be wiped.

4. Static electricity appears on the motherboard.

Power off the main unit, then find this coin cell battery on the motherboard and take it out and leave it for a minute. Then put it back in and turn it on.

5. Discrete graphics card issues.

If you have a built-in graphics card on your motherboard, remove the discrete graphics card first, then connect the display cable to the motherboard's built-in graphics card, and try to boot it.
