With the popularity of computers, the problem of computers failing to start normally also occurs from time to time. When you encounter this problem, don't panic. PHP editor Xinyi brings you some common reasons and solutions for computers that cannot start normally. I believe that by reading this article, you can quickly find out the source of the problem and solve it yourself.
Comprehensive solutions to the problem that the computer cannot start normally. Among many computer failures, "the computer cannot start normally" is the most troublesome thing. The author has been engaged in computer maintenance for a long time and has accumulated some experience in this area. Now I will summarize these experiences to share with my friends.
1. The computer can pass the self-test. Later, you will hear a "beep" sound, a blue screen will appear, and you will be unable to log in to Windows.
This situation is generally caused by system damage, driver or hardware conflicts, viruses, etc., and the solution is relatively simple.
1. During the startup process, select "Last good configuration startup". If it cannot be solved, continue to the next step;
2. During the startup process, be sure to press the "F8" key to enter the safe mode. In this mode, uninstall and reinstall the software with " !" device driver.
3. It is worth mentioning that keyboard failure or not plugged in properly can also cause a blue screen and "Keyboard error or no keaboard present". If there is no problem with the keyboard and motherboard connector, clean the keyboard connector and plug it in again. Tight can be solved.
4. If the power is turned on normally but there is no display, check whether the monitor power cord, switch, and data cable are correct. The monitor may be damaged. These can be easily checked by observing the host status, startup sound, etc.
5. Reinstall the system. It is undeniable that this is one of the ultimate means to solve software problems and is a required course for DIY players.
2. Black screen, no alarm sound
1. Poor contact problem, carefully check the power socket, the power plug behind the chassis, the power connector on the motherboard, and even the switch on the power supply (if any), and replug and unplug it once .
2. If there is a problem with the chassis switch, restart button, or connection line with the motherboard, unplug all the connection lines from the motherboard to the case, and try to connect the switch jumper directly with tweezers.
3. The motherboard is short-circuited. Check carefully around and on the back of the motherboard to see if there is contact with the chassis and other components.
4. The Bios settings are improper, use jumpers to clear the CMOS settings of the motherboard. (This problem mostly occurs due to overclocking or improper hardware settings. If there is no such operation, it can be ignored)
5. The motherboard or power supply is damaged, or even the CPU is burned out. Try replacing it with a new one.
3. The power-on alarm sounds and cannot be started.
1. Poor contact, including graphics card, memory, hard disk cable, power cord, etc. Clean the dust, use an eraser to wipe the gold fingers of the graphics card and memory and re-plug them tightly. These are the most common and easiest to fix. Clean the dust in the chassis, improve heat dissipation, and ensure the normal operation of each fan.
2. The graphics card or memory is damaged or has compatibility issues with the motherboard. Replacement is the solution. If there are multiple memory sticks, you can try using one.
3. Hard disk problems. If "Non System Disk Or Disk Error, Replace and strike any key when ready" or "Hard disk not present" appears during startup, if the words "disk, HDD, etc." appear, you can remove the hard disk power cord and Check the data cable until the hard disk itself.
When "Boot from ATAPI CD-ROM: disk boot failure,insert system disk and press enter" appears, you can directly enter the Advanced BIOS Feature option in the bios and set the First Boot Device to HDD-0. (That is, the first boot is from the hard disk), save the settings and restart.
If it cannot start after adding a hard disk, just set the newly added hard disk as the slave disk (Slave). This can be solved by using the jumper method marked on the hard disk. .
4. No display when turning on the computer
After turning on the computer, the monitor does not display and is still in sleep mode.
This may be caused by poor contact between the memory module and the motherboard memory slot, or the memory module is damaged, or the motherboard. Damage to the memory slot may also cause this failure. If it is a poor contact, just pull out the memory stick and wipe the gold finger of the memory stick back and forth to solve the problem. If the memory is damaged, the problem can only be solved by replacing it. . Also, when there is no display when the computer is turned on due to a faulty memory module, the host's prompt speaker will usually beep for a long time. Poor contact or damage to the general graphics card may also cause this failure.
This problem may occur due to the motherboard. This type of failure is usually caused by damage to the motherboard or damage to the BIOS by the CIH virus. Generally, all data in the hard disk will be lost after the BIOS is damaged by the virus. Therefore, we can determine whether the BIOS is damaged by checking whether the hard disk data is intact. There are two other methods. Reasons that may cause this phenomenon:
1. Because there is a problem with the motherboard expansion slot or expansion card, the motherboard does not respond and has no display after plugging in expansion cards such as sound cards.
2. For current jumper-free motherboards, if the CPU frequency set in CMOS is incorrect, it may also cause a no-display fault. This can be solved by clearing the CMOS. The jumper to clear CMOS is usually near the lithium battery of the motherboard. Its default position is generally short circuit 1 and 2. Just change it to short circuit 2 and 3 in a few seconds to solve the problem. For old motherboards, if the user cannot find it Once the jumper is reached, just remove the battery, wait until the power-on display enters the CMOS setting, then shut down the computer, and put the battery up to achieve the purpose of CMOS discharge.
For the failure of the motherboard BIOS is damaged, we can plug in the ISA graphics card to see if there is a display. If there is no startup screen, we can also make a floppy disk that automatically updates the BIOS and refresh the BIOS. However, some motherboards have a damaged BIOS. , the floppy drive does not work at all (as far as I know, this is the case with Chengqi's motherboard). At this time, you can try to use hot-swapping to solve the problem. However, according to my personal experience, in addition to requiring the same BIOS, using hot-swapping may also cause problems. As a result, some components of the motherboard are damaged, so the reliable method is to use a code writer to write the BIOS update file into the BIOS (where mobile phone repairs are generally done, there are code writers).
Regarding the motherboard damage, some may be caused by battery leakage after the motherboard has been used for a long time, causing the circuit board to become moldy (for old motherboards in the past), making the motherboard unable to work properly. In this regard, we can clean it thoroughly. Whether it can solve the problem, this method can also cure the poor contact between the motherboard slots.
Cleaning method: Use tools to unplug the BIOS and CMOS battery from the motherboard, then use a hard brush and washing powder to clean all components thoroughly, and finally rinse them with tap water. Wait for the motherboard to dry before trying again (the author has used This method has cured several motherboards without any side effects).
5. The motherboard COM port, parallel port, or IDE port is damaged
Such faults are generally caused by the user plugging and unplugging related hardware while the power is on. At this time, the user can replace it with a multi-function card, but before replacing it, the motherboard must be disabled. The built-in COM port and parallel port (some motherboards even have to disable the IDE port before they can be used normally).
6. CMOS settings cannot be saved
This type of failure is usually caused by insufficient voltage of the motherboard battery, which can be replaced. However, some motherboard batteries cannot solve the problem after replacement. In this case, there are two possibilities:
1. There is a problem with the motherboard circuit. You need to find a professional to repair it; 2. There is a problem with the CMOS jumper on the motherboard. Some people set the CMOS jumper on the motherboard to the clear option due to human fault, so that the CMOS data cannot be saved.
7. After the motherboard driver is installed, the system crashes or the CD-ROM disk reading speed slows down.
I have encountered this phenomenon many times on some non-brand-name motherboards. After installing the motherboard driver, restart The computer cannot enter the Windows desktop in normal mode when starting the computer, and the driver cannot be uninstalled under Windows, forcing the user to reinstall the system.
2. The climbing computer cannot start normally?
If you cannot enter the system normally, press F8 immediately after booting to see if you can enter safe mode or the last correctly configured mode. If possible, the registry will be automatically repaired after entering, and you can recall what you did when some abnormal phenomena occurred in the past few times. If you suspect that some application is causing the problem, you should uninstall it, exit normally, and then reboot into normal mode.
3. What should I do if the computer cannot start normally?
If it does not start, jumper the host under Baidu to start.
If it still doesn’t work, there may be a problem with the power supply or motherboard, and you’ll have to change it back and forth.
Three things to do when booting up, check if the cables are connected correctly, insert and remove the memory or test a single one, press the upper and lower case of the keyboard to see if it can start.
4. How to troubleshoot the cause of the computer failure?
Yes Once it starts, there is basically no problem. Even if the hard disk is broken, it just cannot enter the system, which will not affect the computer startup. If it still cannot start, the screen is still black, then continue to check the memory ~ motherboard ~ CPU. Many failure to start is not a fault, it is just a poor contact of the memory, just plug it again and it will be fine. No matter how hard you plug in the memory, it doesn't work, so try replacing it with a good one. If it still can't start, then you can suspect the motherboard. Generally, the CPU is not suspected because the chance of the CPU being broken is very low.
Among computer components, the most damaged one is the motherboard.
5. The CPU is hot but the computer cannot start normally?
(1) Excessive CPU temperature will not only cause the computer to freeze, but also cause the computer to crash or restart. However, when the radiator falls off, it will cause the computer to shut down as soon as it starts. If there is an alarm sound all the time, it means there is some bad contact between the memory and the memory slot.
(2) The CPU temperature is too high, usually because the radiator fan has too much dust, or the fan is damaged, or the radiator falls off. When the temperature is too high, and the motherboard has set a protection temperature, when the set temperature is reached, The power will be automatically cut off, and the computer will shut down or restart. However, if the radiator falls off, the temperature will rise very quickly as soon as it is turned on. It will reach the temperature set by the motherboard in a few seconds. The motherboard will activate the self-protection circuit and immediately cut off the power and shut down. .
(3) Solution: Turn off the power, turn on the host, clean the dust from the CPU fan, if you find that the radiator has fallen off, reinstall the radiator, wipe the memory module with an eraser a few times, and then plug it back in. , this will solve the problem.
It is recommended to troubleshoot according to the following methods:
1. Verify whether the power indicator light is on.
2. Observe whether the screen lights up and whether you can see the Samsung logo with a blue background.
3. If you can see the Samsung logo screen, it is recommended to restore the BIOS default settings. That is, when the Samsung logo screen appears when you turn on the computer, press F2 to enter the BIOS, then press F9, select Yes, and then press F10 to save and exit.
4. If restoring BIOS fails, try to see if you can enter safe mode. That is, when the Samsung logo screen appears when you turn on the computer, press F8 and select safe mode to enter.
5. If you can enter safe mode, it is recommended to uninstall recently installed software programs in safe mode, and conduct virus scanning and observation on the system.
6. If the above operations are ineffective, it is recommended to reinstall the operating system and observe (please back up your important data before reinstalling the system).
7. If the system cannot be reinstalled or the system reinstallation is ineffective, it is recommended to contact the Samsung authorized after-sales service center for testing. If the notebook's power indicator does not light up after pressing the power button, you need to check whether the socket and power adapter are turned on and plugged in. If there is no problem, you need to directly contact the Samsung authorized after-sales service center for testing.
For many office workers, the problem that the computer cannot start office software normally may become a headache. There are usually several possible reasons for this, such as software glitches, system compatibility issues, virus infections, hardware failures, etc.
First, we can check the compatibility of the office software and the operating system. Some older versions of office software may not run properly on newer operating systems, so they need to be upgraded or use compatibility mode.
Secondly, if you suspect that the problem is caused by a virus infection, you can install anti-virus software to perform a full scan, remove the discovered viruses, and then try to restart the office software.
If the above methods cannot solve the problem, you can try to reinstall the office software. First, completely uninstall the original software, and then re-download and install the latest version of the software.
If it still cannot be solved, then you need to consider that it may be caused by a hardware failure. You can check whether the computer's hard disk, memory, CPU and other components are normal and whether there is any damage or failure.
To sum up, there are many possible reasons why the computer cannot start office software normally, and there are also many solutions. By trying the above methods, I believe it can help you solve this problem and get your work back to normal.
Thank you for reading this article, I hope it can help you better solve the problem of starting office software on your computer.
The inability to turn on the phone is related to your improper operation before shutting it down, right? For example: playing games, watching videos, operating large things, using the computer for a long time caused by card? Or downloading inappropriate things, deleting system files, or shutting down the power supply, etc. The fault will not happen for no reason, right? Press the power button and try turning the machine on and off repeatedly, and leave it for a while. If it really doesn't work, just reinstall the system. If you can't reinstall it yourself, spend 30 yuan to find a repairman to help you.
As long as your computer does not freeze, have a blue screen, or suddenly shut down, it will not be like this when you start it up. If you have any questions, please ask me.The asus computer cannot start normally

Open the machine and retighten the memory, graphics card, hard disk and other devices;
Because the xmp mode itself is an automatic overclocking, after adjusting the voltage, it conflicts with the automatic overclocking (xmp mode) of the memory module, causing the computer to fail to boot. The solution is as follows:
1. At this time, you need to reset the motherboard bios and you need to cut off the power.
2. Disconnect the motherboard button battery, wait 10 minutes, and then quickly press the power button 5-6 times.
3. Wait another 20 minutes.
4. After completion, replace the button battery and power on
