The computer started up after a move, and the screen was black

Dude, you're not simple, it's such a hard work. There are two lights on the computer, one is a power light, and the other is a hard disk light. Since there is only one light on, it must be that the hard disk light is not on, then you pay attention to your hard disk first, if the power supply of the hard disk is connected, but the interface is wrong, there will be a small sound when the hard disk is generally turned on (the ear will be heard by leaning on the hard disk, it is more regular, it is generally a "special" sound), if so, you are connected to the wrong wiring of the general hard disk, after all, the possibility of the hard disk being broken is not very likely.

Second, when you turn on the computer, see if your mouse, keyboard, and monitor have ever lit up, if not, then there is a problem with the motherboard. Third, if it is lit and there is no problem with the wiring of the hard disk, then it depends on the CPU, because although you have removed the graphics card and network card (your network card is independent?) I believe your CPU hasn't been removed, right?

See if your CPU fan is spinning, if not, it is estimated that there is a problem with the wiring of the CPU. In short, when this problem occurs, the possibility of direct hardware damage is relatively small (except for the motherboard), and most of it is a wiring problem.

There are too many possibilities, but I personally think that it is unlikely to be bad, it should be a problem with the line, do the power supply and CPU fans turn? And is the signal cable of the chassis connected to the motherboard corresponding? There are too many possibilities If no one around understands it, it is recommended to send it for repair.

It may be that the capacitor is burned or other problems It is recommended to go to the place where the screen is repaired Repair If there is a small problem, it can be repaired for 50 yuan.

There are several scenarios where a black screen can be on your computer:

1. If the screen has white words on a black background or a cursor in the upper left corner, the system file is damaged;

2. During the computer networking, the Trojan virus was infected and an incompatible driver was installed;

3. The virtual memory set by the computer is insufficient;

4. The hardware settings are overclocked;

Solution: 1. Select the appropriate system according to the computer configuration and reinstall it;

2. Select the system with the right hardware and reinstall it;

3. Install the physical memory size of the computer, reset the virtual memory and select the location;

4. Reset the normal operation frequency of the hardware.

The black screen of the monitor after the computer is moved, it is likely that the internal hardware of the host is caused by vibration, especially the loose memory module, which is caused by poor contact, and it is not excluded that the hardware is damaged, such as the monitor and its connection. You can do the following:

1. Shut down (if the short press of the power switch is invalid, press and hold the switch until the power indicator goes out or directly unplug the power cord) Power off and open the case, check whether the hardware and wiring connectors inside the host are installed in place, especially whether the data cable between the graphics card and the display and the power cable of the display are connected normally. If it still doesn't work, consider that the cable or graphics card is damaged, then replace it with a new one.

2. Re-insert the memory module and graphics card, and wipe the gold finger with an eraser in one direction (the back of the thumb fingernail is also fine), if possible, it can also be installed in different memory slots, and then turn on after installation. The above may need to be repeated, and if it doesn't work, you need to replace the memory module. If you have more than two memory modules, you need to test them one by one.

Note: Before operating, touch the wall with both hands to release static electricity or wear anti-static gloves.

3. If the monitor is not powered on (the indicator light is not on), check whether the power switch is turned on, then check the back of the monitor, plug the power cord plug connected to the monitor upwards (the power cord can be replaced if possible), and check whether the other end of the power cord is powered on to the socket.

4. If the host can be displayed when connected to other monitors or the display of this machine is connected to other normal hosts and still cannot be displayed, it means that the display is damaged and needs professional maintenance.

Is the monitor broken?

You can look at it even on other monitors.

Is there a problem with the graphics card. Plug it back in.

Whether the hard drive is not connected.

Anyway, if you don't connect to one place, it will be like this.

1.The computer host is running normally, and the monitor screen is black, at this time, first see if the power indicator of your display is on, if the light is off, it may be that the power plug of your monitor is loose, try to plug the plug again; 2. If the host is working normally, the power indicator of the monitor is on, but the monitor screen is black, it may be that the transmission line connecting the computer monitor and the computer host is loose or broken. 3. If it is not a black screen caused by a loose power cord or data transmission cable, it may be a loose graphics card of the computer host, which requires the opening of the computer chassis, to open the chassis, first of all, there must be tools such as a screwing knife, remove the graphics card, wipe the ash on it, and then install it, to see if the fan of the graphics card is working normally, if the fan does not work, it can cause the graphics card temperature to be too high and the screen is black; 4. If it is not the poor contact of the graphics card, it may be that the memory of the computer is loose in the card or because there is too much dust in the card slot, resulting in poor contact, open the computer case, check the memory card, unplug it, wipe it clean, and plug it in force; 5. If it is not a problem with the memory card, see if the CPU fan is working normally, if the fan does not work, it may be due to the high temperature of the CPU, the heat dissipation is not timely, and the computer starts self-protection; 6. If none of the above is true, then see if there is a problem with the software, whether there is poisoning or special software installed that causes software conflicts during runtime, resulting in a black screen on the computer;

If the accessories are exactly the same, then you have no problem doing this at all. Now the black screen is because the main boot of the system is different, you can enter the PE maintenance system and reboot with the boot repair software. Definitely.

Of course, then you have to install the driver, after all, each accessory has its own unique driver. It's good to drive life with it. If you're afraid of trouble, reinstall it and get rid of the C drive.

There was no mark at all.

The plug is not plugged in properly.

The computer is overheating. Graphics card driver issues It is recommended to drive life update drivers.

The program is not compatible or Windows automatic update causes problems, it is recommended to turn off win10 automatic update.

If you are not sure, you can also try reinstalling the system.

Can you tell me that both of your hard drives are serial? Is it the shape of the thin data cable or the shape of the parallel port is very thick and wide?

Or 250G is a parallel port and 1T is a serial port.

In the past, parallel eloquence needed to be changed to jumpers, and that method of change required you to do it manually.

And it must be serial.,The most you can do is change the hard disk of it to the first boot item.,You have to make a system for this hard disk.,Take your 250 hard disk as a slave disk in the future.。 This setting can be done completely in the BIOS.

This should have little to do with a hard drive.,System problems.。

The explorer of the system did not start, this situation is difficult to solve by modifying the settings, you can only reinstall the system, reinstall the system, and continue to ask me if you install the system yourself, go to the computer store to reinstall the system once about 20-40**. If you have any other questions, you can continue to ask me, and remember to adopt them if you are satisfied, thank you.

See if this will be the case in safe mode (without driver) and PE mode.

If it's okay, prove that the hardware is fine.

Then you reinstall the system.

It is to be noted that. You say you have 3 hard drives, except for the hard drive with the system, the other two are converted to logical partitions.

The black screen on the computer is mostly because there is a problem with the hardware, first check the quality of the Hongwu power supply, re-insert the memory module base and the graphics card to try, not to check the graphics card wheel, motherboard and other hardware.

The external power supply is insufficient, causing some old displays or some displays with high power consumption to fail to start normally, which is one of the causes of the black screen failure caused by the failure of the display itself. Or the external power supply voltage is unstable, too high or too low may cause the display to not work.

The failure of the display switch circuit is the main cause of the black screen failure of the display. Simple ones such as damaged power switch or internal short circuit; Common ones include damage to the switch or damage to its peripheral circuit components.

The failure of the output circuit or picture tube and its power supply circuit is also the main cause of the black screen failure of the display. In particular, the damage of the high-voltage pack, which is more common in some miscellaneous displays that have been used for many years or are of poor quality, resulting in no display black screen failure.

To check the power supply of the case**, we generally use the alternative method to detect. Put the power box on another computer and give it a try. Someone abroad has introduced another way to test whether the ATX power supply is working normally, first check the external switch on the power box to see if it is in the OFF gear.

Then convert it to 115V gear, so that the power cord on the power box has power.

Secondly, prepare a 6-7 cm power cable, connect the power cable with the power cord socket again, and check the power cords of the hard disk, CPU fan, and optical drive at the same time. Connected. Then, if there is a secondary switch behind the power box, if there is, turn it on.

Finally, check the power supply fan. If there is a problem with the chassis power supply. The case power supply fan won't turn.

Is it a CRT monitor or an LCD monitor?

If it is a CRT (old style big head), it is estimated that it is damp or aged. CRT should be dustproof, magnetic, high temperature, strong light, etc., such as stupid Xiangguo will be affected if you use it in those environments.

If it is LCD (liquid crystal), either the gum of the display screen is old and enviable (this can't be helped), or the circuit board has a question (maybe the line is loose or something, it can be repaired). Miscellaneous LCD is prone to this problem, and there are many copycat self-assembled LCDs on the market.

Also, it's not about the display, it's about the data cable, or the socket, or the graphics card (this is less likely).

The first reason is a system failure.

If there is a problem with your computer's system, such as incompatible patches, software, or drivers, or the system itself is missing some files, it will lead to a black screen.

If it is a solution to a system failure, there are two ways, the first way is to turn the computer off and start it back on at the same time, press and hold the F8 key on your keyboard to enter the advanced boot option.

Once you're in the Advanced Boot Options, select Perform the Last Correct Configuration from your Advanced Boot Options. Then press enter, and after the execution is completed, you can enter the system.

The second way is to reinstall the system. Now it's not hard to reinstall a system. You find another computer, and then use your USB flash drive to make a boot disk, and then prepare for a system image from the Internet, and you can install the system when you are ready, I myself have written several tutorials to install the system, and I attach the link below.

3U disk reinstall win10 system tutorial。

The third reason is that the BIOS is not set up, that is to say, the BIOS of your computer is not set as the first boot item when the BIOS is set, this reason, the solution is to press F2 to enter the BIOS, and then enter the boot menu to set your hard disk as the first boot item in it, you can.

The fourth reason is your motherboard or your memory, if it is your computer motherboard or memory that cannot be turned on, you can teach your computer to boot to see if your memory module is Bao Dong or whether there is dust to check your hard disk, or whether there is a problem with the motherboard.
