After shutting down, the screen is black when you turn it on again, and there is nothing on the desk

There was a problem with the self-startup of the explanation.,I've encountered this situation before.,The Internet says that you search on the C drive.,And then put it in the start menu The startup item can be solved.,I tried it at the time and didn't succeed.。 It is recommended to back it up and reinstall it, so far I haven't found it.

to a better workaround.

The above are some personal opinions, I hope it will be helpful to you

Let's check out these places.

Good luck you don't have to reinstall the system

I had a similar problem, and finally used Kingsoft Poison (2011 version free) to sweep away a worm that tampered with the desktopThe problem seems to be solved, so it doesn't hurt to give it a try! If not, check the hardware!

There is a problem with the system restore, isn't it just to restore to the normal point.

1. Restart the computer, keep pressing F8, enter the safe mode, "Advanced Boot Options", "Last Correct Configuration", try to see if it works, if not, continue to come. If it doesn't work, select it in the interface just now"Safe mode">> Start normally >> After going to the desktop>> Full antivirus. Use software to disinfect viruses.

2. Open the 360 security guard and select the right-hand side, more》360 system first aid kit > system repair > select all >> repair now > network repair >> start repair. Click: After "Start First Aid" is finished, after the computer restarts, open the "File Recovery" at 360 points, select all, and delete the files completely!

3. If it doesn't work again, unplug the graphics card and memory module, erase it with an eraser, and then sweep it with a brush, clean up the slot dust and fan, replace the memory slot, etc.! Be careful when disassembling the computer, and remember where the parts are disassembled.

4. If the above methods still don't work, you need to "one-click restore" or "reinstall the system"! (But you need to back up your system before!) )

5. If the above fruit noodles are no, choose"Computer repair"Status, "Start Repair" automatic repair, (usually this repair takes a long time, don't worry about him, the computer repairs itself.) )

The black screen does not show the desktop is a desktop startup failure, which can be started manually. Ctrl+Alt+del to open the task manager, file, run a new task, enter, and check the system management permission to create this task, OK, win+r, enter regedit, enter the following path in turn, select winlogon, double-click the shell, if the value data of the shell is correct, otherwise it will be changed, OK.

1. Whether the computer monitor and the host are normally connected to the power supply, and whether the power indicator is on. 2. If it is a notebook to check the power indicator of the computer, if it is not lit and the computer is connected correctly, it is very likely that there is a problem with the motherboard, please send it to the warranty point for repair in time.

Enter safe mode when powered on. Then restore the system. That's it.

The laptop screen is black, it may be a problem with the software or hardware.

One, the black screen caused by the software.

Sometimes after installing some software or hardware drivers, you find that after restarting, the computer can't enter the system and the screen has been black, which is the black screen of the laptop caused by the software. If the black screen is caused by software, take the Windows system as an example, you can restart the machine, press the F8 key several times when booting up, and bring up the system's boot options menu.

Once the System Boot Options menu comes out, select Enter Safe Mode. If you can enter the safe mode normally, you can delete the software or driver installed before the black screen in the safe mode. Then restart the machine and see if the laptop can fix the black screen issue.

Second, the hardware causes the laptop to have a black screen.

Hardware-induced black screen for the following reasons:

1) The cause of static electricity, sometimes static electricity will cause the circuit of the notebook motherboard to be abnormal, resulting in no reaction on the screen after the power is turned on. You can try to turn off the battery and power of the laptop, and then press the power start of the laptop several times to let the machine release the static electricity. Then connect the power supply, turn it on, and see if it can solve the fault.

2) The memory is loose or the memory has a hardware failure. There are several major components of a laptop computer, including the CPU, motherboard, memory, and graphics card. These parts are indispensable, as long as one of them has a problem, it will cause the laptop to not function properly, the most common is that the boot does not respond.

In general, the probability of CPU and motherboard failure is relatively small, and it is more common for the laptop to fail to boot due to loose memory. At this time, first remove the battery and power supply of the notebook, if it is not difficult to remove the computer, you can open the back cover of the notebook by yourself and reinsert the memory. After plugging in the memory, power it on again, start the machine, and see if you can solve the fault.

3) The LCD part of the notebook is faulty. There are some notebooks that are a little older, and this may be the case. Display components generally include displays, data cables, and some other small parts.

If you have a desktop monitor, try plugging it to the VGA display connector on your laptop, and then switch the display to the VGA external display on your laptop. If you can switch to an external monitor, it means that there is a big problem with the display part.

4) The graphics card hardware is faulty, the graphics card is responsible for the source of all the display output of the computer, so it has a problem, and there is no display on the screen. If the graphics card is broken, the average user can't solve it, and the only way to solve it is to find the computer's after-sales service. If the notebook is within the warranty period, it can be taken for free inspection and repair.

If you don't go out, don't use the battery... If it's more out of the home. Just buy one.

There is no portable hard drive or USB stick plug plugged.

Then the battery is broken! If you have a guarantee, if you have a guarantee, go fix it.
