Computer black screen is a common problem, but sometimes it may appear that the computer boot black screen only has the cursor flashing. What should I do? The following is my solution to the black screen when the computer is turned on and only the cursor is flashing, for your reference.
When such a situation occurs in your computer, do not operate blindly because of worry, because your blind operation may completely crash the system and have no room for recovery. Therefore, first of all, we should calmly think about whether we have carried out any operations or browsed any websites before. Because this situation is likely to be caused by the virus. Such problems may occur when the virus deletes the partition table or system startup file of your system.
First of all, we need to restart. When starting up, keep pressing F8 key. If you keep pressing it, a white menu with black background appears. Fortunately, your system is not in trouble. We enter the security mode of the system. After entering, we kill virus and repair the missing system files. Then restart it, and maybe the problem will be solved smoothly.
If you keep pressing F8 but don't respond, it means that the problem of the computer is serious. At this time, if your system has been backed up previously, there may be a glimmer of vitality. Restart again. Press the up and down keys of the keyboard continuously before starting the machine. If a menu selected by the system appears, it shows that the problem is still not big. It's just a problem of the system, not the hardware. Select to enter the restore program for system restore. After restore, of course, you can start up smoothly.
If you can't wake up the black flashing cursor interface no matter what key you press, the problem is terminally ill. It may be concluded that the problem can not be solved through the hardware operation. At this time, you may need to use the PE system. Restart, enter BIOS, select USB flash disk to start, and enter PE system. After entering, repair the system problems, or antivirus, or repair. After the repair is completed, restart the machine and the problem may be solved.
Check whether the display is damaged. The first step is to see if our computer monitor is burnt out.
2. The computer host fails. Faults such as damaged host power supply, excessive overclocking and incorrect CMOS setting of the motherboard will cause the black screen cursor flash of desktop / laptop when starting up, so these problems should be eliminated first.
Restart our computer. If you can't see or see the start menu, we can press the shortcut key to restart the computer (Ctrl + Alt + Del or win + R). Of course, if you really won't restart, you can press the host switch, turn off the computer and turn it on again (I don't recommend this).
Then, after the computer display light is on, keep pressing and holding the F8 key until you enter the safe mode. At this time, enter the desktop from the safe mode, and then kill the virus on the computer.
Press F8 to enter the selection page, or select the "last correct configuration" option to enter.
If the above operation does not solve the problem, I suggest reinstalling the system.
