Reinstall the system, use an 8G or more memory card or U disk to go to someone else's computer or go to the Internet café, ** U master one-click installation plugged in U disk production, complete in ** a pirated system installed on the card, take it to plug in their own computer boot press F8 and other display content to select the new machine win10 start to the desktop will jump out of the one-click installation, click down the C disk below to confirm the progress bar to 100% restart the computer, unplug the card and wait for more than ten minutes to install it OK. If the progress bar appears halfway through? Error 1818 has a problem with the system package re-a**.

The computer is just turning on the fan, and the monitor is not responding, there must be a problem with the computer hardware, and it is best to use the replacement method to eliminate the problem, and the judgment method: 1. Press the upper and lower case keys on the keyboard. The light is on, indicating that the graphics card, monitor, and other hardware are faulty.

2. If the keyboard light does not light up, it means that it is a memory, CPU, motherboard, or power supply problem. Solution: 1. If the keyboard light does not light up, first wipe the memory module with an eraser, and check whether the gold finger of the memory module has any burnt marks.

Replace the memory in the slot. 2. Check the capacitors and resistors on the motherboard to see if the capacitors are bulging, whether there is a burning smell on the motherboard, and clean up the dust on the motherboard. 3. Remove the CPU fan, power on and turn on, test whether the CPU has a temperature change by hand, if not, the CPU is not working, either the motherboard is broken, or the CPU is not plugged in properly, and the CPU is re-plugged.

4. Power supply problem, although the power supply is powered on, but the motherboard can not work normally, replace the power supply and try it. 5. If the display card is loose or oxidized, the keyboard light will be on, the screen will not be displayed, wipe the gold finger of the graphics card with an eraser, and check whether the capacitance on the graphics card is bulging. 6. Minimize the test method, only leave the power supply, motherboard, CPU, memory, graphics card, keyboard, monitor, unplug all the wires on the rest of the motherboard, use a screw knife to short the switch pins, if normal, add the rest of the hardware, piece by piece, until the cause of the problem is found.

You can block the screen of the notebook,Then see if there is a backlight,If there is a backlight,It should also be a software problem,If it has been in a state of black screen since booting,There is no backlight,Then it should be a hardware problem。

Hello friends, please help in time, in this case, you first check whether the power and data cable connection of the monitor is normal, if it is normal, please try the following methods:

There are about three reasons for this situation, and there are 3 ways to deal with it!

1. Poor memory contact, it is good to plug and unplug from the new.

2. Dust killer, clean up the dust inside the computer, clean it, and there will be no problem!

3. Internal accessories contact problems, short circuits, etc., solutions, directly pull out the big power supply on the motherboard after power-on, not CPU power supply! Plug it in immediately, and then turn it on, most of the situation can be solved.

1. Please try to press the Function Key Combination to increase the brightness of the screen, turn on and off the toggle display, to avoid the screen brightness being too low or the black screen of the computer not being displayed due to the screen being turned off. 2. Press the F2 button when you boot up and enter the BIOS interface to check if it is displayed normally. (1) If the BIOS interface does not display the black screen, it may be a hardware problem of the computer.

Check the memory module,Hard disk,If the boot does not come out of the motherboard logo, check the memory module,If the logo is out, look at the hard disk,It is best to have accessories to replace,If not, go to the computer repair shop,It's best to look at him,And then let the repaired check the memory module,If you get into the BIOS,Start it with a U disk to see。

The computer can't be turned on with a black screen, which is too many possibilities. There are both hardware and software aspects. You'll have to describe the reason for your computer in detail. We'll be able to help you figure it out.

When you encounter a black screen on the computer and cannot be turned on, first check whether the power supply of the monitor is normal, and then check whether the power supply of the host is abnormal.

When the computer screen is black, you should consider whether the host is working at this time. If the host is working, it is a problem with the screen; If the host is not working, then you need to check the power supply, hard disk, CPU and memory module of the host.

It is recommended to replug the memory module and carefully check whether the relevant connection cable is normal.

There is a high probability that there is a problem with the internal hardware, which can be ruled out and checked in turn.

There are several reasons for laptop black screen failure:

No display on boot and no response.

Generally, the voltage of the notebook is 12V-24V The power is about 60W, which depends on the specific parameters of the notebook, and the performance of the high-power general graphics card will be higher. In this case, it is necessary to consider whether the power adapter is damaged, and there is also a situation that is the motherboard circuit, which is complicated to repair and costly in terms of difficulty.

2. There is no display when it is turned on, there is speed, and there is no cursor.

The laptop is loaded with a power supply, the fan rotates, on behalf of the motherboard is energized, but it does not mean that the power supply is not damaged, the first thing to rule out is the memory failure, the general notebook, especially the notebook with a long age, due to the loose memory of the notebook or the loose card slot, it is easy to cause the state of not being able to boot, the performance point is the boot turn, the screen is not displayed, in this case, just open the back cover to wipe the memory, and reinsert it.

3. There is a display when you boot up, and the cursor flashes.

The laptop boot has a display that means that it has read the BIOS, and there is a problem when loading the hard disk and the system, then the answer is obviously in the hard disk and the system, replace the system, and detect the hard disk. Of course, it cannot be ruled out that it is caused by the poor contact of the hard disk, you can manually shut it down, plug and unplug the hard disk and try it.

4. There is a display when the boot is turned on, there is an icon, the card does not move or the display is not normal.

The display is abnormal, the first point of failure lies in the display, which belongs to the hardware category, do not move the system without authorization.

Laptop won't turn on black screen? Failure analysis and timely solution.

Solution: connect to an external desktop monitor, eliminate the problem of the graphics card, after connecting the external monitor, the keyboard switches to the external monitor, and generally needs to press the function key to add the projection function before the external output, here to talk about it, although some computer notebooks provide external output, but from a practical point of view, not all notebooks factory this function is up to standard, the implication is that some notebooks this interface is chicken ribs.

If the external display is normal, you can start from the screen, the screen problem is generally the cable, the display, the high-voltage board, the biggest possibility should be the cable problem. 】

5. There is a display when the boot is turned on, the screen is dark, and it runs normally.
