Hey guys! I'm your digital problem solver, Brother Jiexiu. Today I want to share with you a common computer annoyance: "the boot display is not lit but the computer is running all the time". What's going on here? Don't worry, let's find out together!
Q1: The display is not lit, how to judge the electricityThe brain is still running?
When you press the power button and hear a familiar boot sound, a flashing hard drive light, or a CPU fan turning, your computer has actually woken up from its slumber, but the "big eyes" of the monitor have temporarily struck.
Q2: Why is this embarrassing situation happening?
Hardware connection failure: It may be that the power cord of the display is loose, VGA HDMI and other ** wires are not in good contact, just like the "little noise" between the computer and the monitor, the signal transmission is not smooth, of course, you can't see the picture.
Graphics card issues: An error in the graphics driver or a malfunction in the graphics card hardware can also cause the display to be undisplayed. At this time, your computer may be thinking os: "My graphics card is a bit emo, the screen won't light up".
The memory module is faulty: If the memory module is not in contact with the contact or is damaged, although the computer can start, due to insufficient memory or unable to read the data normally, the monitor will naturally "close its eyes and recuperate".
The BIOS settings are abnormal: Sometimes, if the boot device in the BIOS is adjusted in order or the display output function is turned off by mistake, the monitor will enter "incognito mode" even when the computer is working.
Q3: How to solve this problem?
A: In view of the above situation, Brother Jie Xiu provides you with a set of practical solutions:
Restart the law: Try the simplest thing to do first - unplug the power supply, plug all the cables back in, and then turn it on to see if it returns to normal. After all, "restarting" is sometimes so magical!
Check the connection: Carefully check whether the power cord and ** cable of the monitor are firmly plugged in, and try to replace other interfaces or borrow another monitor for testing to see if it is a connection problem.
Reinstall the graphics card driver: If the graphics card driver is to blame, enter safe mode to uninstall and reinstall the graphics card driver, so that the relationship between the graphics card and the monitor can return to the honeymoon period.
Check the memory module: Open the case, make sure the memory module is properly inserted and secured, and try replacing the memory module if necessary.
Restore BIOS settings: If you suspect a problem with the BIOS settings, press a specific key (usually F2 or Delete) continuously to enter the BIOS interface during boot to restore the default settings or check the boot order of the device and display the output options.
To sum up, in the face of the situation that the monitor is not lit but the computer is still running, we must first stay calm, and then follow the steps provided by Brother Jie Xiu to investigate step by step to find out the crux of the problem. With simple and easy operation, you can be sure that you will soon be able to "open your eyes and talk" the display and bring your computer back to life.
