What should I do if my monitor won t turn on and my computer monitor won t turn on

Discharge the BIOS battery (restore the BIOS factory defaults) It is recommended to plug and unplug the graphics card and memory, clean it up, and polish the gold finger of the graphics card and memory.

First, check to see if the computer has started booting up the operating system when you turn it on. If the operating system freezes, blue-screens, or automatically restarts when the operating system is booted, the partition table and master boot record of the hard disk are normal, and the fault causes such as the corruption of the hard disk partition table, the corruption of the master boot record of the hard disk, and the loss of the hard disk partition end flag are ruled out. The following method is then used to make a diagnosis.

Step 1: Start the computer in safe mode to see if it can boot, if it can't boot, it may be infected with a virus, system files are missing, the operating system is damaged, the hard disk has bad sectors, the hardware device has a conflict or the hardware has a problem, go to step 4; If you are able to start Safe Mode, it may be caused by the hardware driver being incompatible with the system, the operating system is faulty, or it is infected with a virus.

Step 2: Then run the antivirus software, if there is a virus, it may be caused by a virus, restart the computer after the antivirus, if it is not normal, you need to reinstall the operating system.

Step 3: If no virus is detected, you can use the "System Restore" function of the operating system to restore the system, and if the system is normal after the restore, the failure is caused by system corruption. If the fault persists, it may be caused by the incompatibility of the device driver with the system; Then delete the drivers of the sound card, graphics card, network card and other devices, and then install the drivers one by one, restart the computer every time you install a device, to check which device's driver caused the failure, find out, ** the new version of the driver of the faulty device, and then install it.

Step 4: If you can't boot from safe mode, then reinstall the operating system with the installation disc. If you can install the operating system normally, go to 7 steps; If there is a failure when installing the operating system, such as a freeze, blue screen, reboot, etc., which causes the system to be unable to be installed, it should be caused by a hardware problem or a poor hardware contact.

Step 5: Then clean the dust in the computer, clean the gold finger of the memory, graphics card and other equipment, reinstall the memory and other devices, and then reinstall the operating system.

Step 6: If you still can't install the system, it could be a malfunction caused by a hardware issue. Then use the replacement method to check the hardware failure, and replace the hardware after finding it.

Step 7: If the operating system can be installed normally and the fault disappears after installation, it is a fault caused by corrupted system files.

Step 8: If the fault persists after installing the operating system, it may be caused by bad sectors on the hard disk or the device driver is incompatible with the system. If you boot your computer in safe mode, if it doesn't boot, it's a malfunction caused by bad sectors on the hard drive.

Then use NDD Disk Utility to repair the bad sectors.

Step 9: If you are able to boot Safe Mode, it is caused by the incompatibility of the device driver with the system. Then delete the sound card, graphics card, network card and other devices, and then install the drivers one by one, install one by one, and start one at a time to check which device's driver is causing the failure.

If there is a problem in three places, the landlord will use the elimination method.

1. If there are English letters on the boot monitor, but there is no display after passing the windons scroll bar, it means that the graphics card is out of the resolution range, and the graphics card driver or system needs to be reinstalled.

2. If there are no English letters on the display when the computer is turned on, and the display light is yellow or red, it proves that the host has no display signal to the display, and the graphics card is damaged, or there is a problem with the graphics card chip of the integrated motherboard.

3. The lamp is burned out due to the high working temperature of the monitor for a long time, or the circuit board of the display is damaged. (You can try this by changing the monitor to another host, such as going to a friend's house).

Elimination is the most direct and effective method.

I left for a while because I had something to do and let the computer standby, but when I came back, I found that the monitor was no longer available. Hello, you can unplug the signal cable of the monitor first, and then pay attention to whether the light is still changing ,..

When the computer monitor does not turn on, we need to do a certain amount of limb code checking to determine the cause of the problem. Below I will introduce some common workarounds.

1. Check whether the monitor is connected to the power supply, VGA HDMI cable, and power cable, and confirm whether the power is turned on. If the signal cable between the computer and the monitor is loose or broken, the image cannot be displayed. Also make sure that the display buttons are set correctly, such as if the brightness setting is not too low.

2. If your monitor has multiple interfaces, try to replace them with other interfaces. You can replace the HDMI cable, adapter, multi-function adapter, etc., and reconnect the monitor and computer to check if the monitor is working properly.

3. Check whether the CPU of the computer is working normally, you can try to restart the computer. If there is a problem with other devices and peripherals, it will directly affect the normal operation of the display.

4. If the above methods still do not solve the problem, it may be a hardware problem of the display, and it is recommended to contact the after-sales service. At the same time, if you do not understand the relevant operation, it is recommended not to turn on the monitor by yourself, otherwise it may cause irreversible hardware damage.

In short, if the computer monitor is not starved to start, first to determine the root cause of the problem, and then check one by one to try different solutions, if it still can't be solved, do not force the operation, it is recommended to apply for after-sales service or seek professional help in time, so as not to expand the loss.

The computer boots up the monitor and it doesn't respond?

1. If this kind of problem occurs, first of all, you need to check whether the connection line between the monitor and the host is normal, if the connection cable is loose or aging, it will lead to this problem. 2. Check whether the power socket is good, if there is a problem with the socket, it will also cause the monitor to not respond. 3. After opening the host, you can check the situation of the motherboard, if there is more dust on the motherboard, then when the computer starts, the display does not respond.

Suggested workaround:

1. If there is a problem with the connection cable between the monitor and the host, you can replace the connection cable between the monitor and the host, or plug the plug back in.

2. If there is a problem with the power socket, you can replace a high-power power socket to solve the problem that the display does not respond after starting.

3. After turning on the host, if it is dust that causes the problem, it can be cleaned up in time.

4. When the memory of the computer is loose or snapped, you can clean up the memory, or contact the maintenance personnel to replace the memory. After replacement, put the memory modules back on the motherboard in turn, bring the panel of the main chassis, and tighten the main screws, so that the problem of the monitor not responding after booting can be solved.
