    If you have this situation again, you can press F2 to enter the system, your motherboard battery is dead, and then when you force the shutdown, the power must be cut off, and then the BIOS information will change, and you have to turn off the boot floppy drive item!

    Because you are forced to shut down, so it will become like this, your memory module may be loose, take out the memory module and wipe the dust, and then clean up the dust in the case, and you can turn it on, I used to deal with it like this, and now the computer can be turned on normally.

    The computer won't turn on because there is a problem? The most common ways to eliminate the computer boot is that the computer does not respond when booting up, and the most common ones are: the power cord of the computer host is not connected, the monitor switch is not turned on, and the monitor power supply or monitor data cable is not in good contact.

    When we find that the computer does not respond when we turn on the computer, we need to first observe whether the power indicator of the computer is on after the computer presses the boot button, when the power indicator is not on, then it is likely that there is a problem with the power supply, you can check whether the power cord of the host is connected to the external power supply well, whether there is a line failure, etc., when the computer power supply is bad, the computer will not respond when the power supply is bad, these need to do some simple elimination to confirm. When the computer indicator light is on, the CPU fan inside the computer is running normally, then generally speaking, it can be preliminarily judged that there is no big problem with the power supply, and then we will check the monitor to see if the power indicator of the display is on, and whether the display data cable is well connected. At the same time, observe whether the computer keyboard and mouse indicators are on, generally if there is no problem with the host, the computer keyboard indicators and mouse indicators are normally on, this situation often appears on the monitor, such as the display switch is not turned on, the monitor data cable is not connected, or the display power supply is faulty.

    The above computer boot does not respond,We can't find the problem after a simple investigation,It is recommended to use the replacement method,If you suspect that there is a problem with the display,You can take a good one to try,The problem is still the same,Try the data cable too,If it still doesn't work,Then the problem is likely to appear on the host,In short, it can be eliminated as much as possible,So it is easier and easier to find the problem,The general display troubleshooting method is relatively simple,I won't introduce it too much here, The following focuses on the computer boot not responding due to host failure. Troubleshooting methods for computer boot failure caused by computer boot not responding, computer boot no display fault. (No alarm sound) Step 1:

    First of all, check whether the external wiring of the computer is connected, and plug each cable back in to see if the fault is eliminated. Step 2: If the fault persists, then open the main chassis to check whether there is any excess metal in the chassis, or a short circuit caused by the deformation of the motherboard, and smell whether there is a burning paste in the chassis, whether there are burned chips on the motherboard, and whether the capacitors around the CPU are damaged.

    Step 3: If not, then clean the dust off the motherboard and check if the computer is in good condition. Step 4:

    If the fault persists, unplug the reset cable on the motherboard, connect it with other switches and indicator lights, and then use the change cone short-circuit switch to see if it can turn on. Step 5: If you can't turn on the computer, then use the minimum system method, unplug the data cable of the hard disk, floppy drive, and optical drive, and then check whether the computer can be turned on.

    Then connect the above devices to the computer one by one, when connecting a certain device, the fault will recur, indicating that the fault is caused by this device, and finally focus on checking this device. Step 6: If the fault persists, the fault may be caused by devices such as memory, graphics card, CPU, motherboard, etc.

    1.The boot screen can show no signal input, which means that the monitor is fine.

    2.If you can be sure that it is not a problem with the memory and graphics card, then it is only a problem with the connection, check whether the D-connector connected to the display on the graphics card is loose, it may be caused by a bad connection!

    If it's not a contact problem, the biggest suspicion is indeed the motherboard, but don't worry too much, it may also be caused by the settings after you enter the CMOS, you can find the jumper on the motherboard to clear the CMOS to zero, return the CMOS settings to the default state, and then start it to see. If you can't find the clear jumper, remove the battery from the motherboard and install it, and the effect of clearing is the same.

    If the problem persists, then there is a high chance that the motherboard BIOS will be damaged.

    Press F8 to enter the last normal start when you turn it on.。。

    If it doesn't work, reinstall the system.

    Can you provide a specific **?

    We only know the specific fault of your computer!

    If your computer won't boot into the system, it's usually caused by a corrupted or missing boot file of the system!

    If you have a USB disk boot disk in your hand, it is better to solve this problem!

    After entering the PE system through the USB drive, you can solve this problem by using the system repair tool provided in it to repair the boot file!

    Boot file repair.

    If the boot file repair can't be solved, it means that it is not a problem with the boot file, and it may be that the system needs to be reinstalled!

    If it is a hardware problem, such as 3 short and one long fault prompt, it is a memory problem!

    Therefore, specific problems should be analyzed according to specific phenomena in order to accurately repair failures!

    I have encountered this situation, the computer motherboard burned out, it is recommended that you do not forcibly shut down the machine, go to the nearby electronic market to replace the motherboard, I remember that I spent 270 yuan to replace one at that time. Hope to adopt.

    Generally, it is a hardware starting problem, or the system file is lost, from the safe mode, safe mode with network, safe mode with command prompt, the last correct configuration boot to recover, can not boot normally You check from the following aspects.

    1. There is too much dust in the machine, and poor contact will cause a crash, clean the chassis, and plug all the connections tightly and firmly. Pay attention to the connection of the graphics card and monitor.

    Second, the memory module failure, mainly the memory module is loose, if it is a memory module quality problem, the memory needs to be replaced.

    3. Check the heat dissipation of the CPU and graphics card, remove the dust from your hands, oil it, or replace the fan.

    Fourth, the power supply voltage is unstable, the power supply is insufficient, and the power supply with high quality Bi Roll Sen is replaced.

    5. Replace the motherboard battery and set the BIOS to factory default.

    6. If the system files are lost, repair the system and reinstall the system.
