If you often deal with computers, the computer cannot start, the computer cannot be turned on, the computer cannot be turned on, I believe you must have encountered it; based on my many years of experience in computer maintenance analysis , there are many reasons for this. Let’s list and analyze them one by one: After turning on the computer, the fan rotates and there is a self-check sound, but suddenly there is no power. 70% of the reasons may be that the power cord is broken. The computer starts up normally, but the monitor suddenly stops showing during the startup process and the host computer is running. First, check whether there are other convenient external devices, such as USB flash drives and digital cameras, plugged in before the computer is turned on. It is recommended to unplug them and plug them in again after the computer boots up and enters the system normally. In fact, this is a small problem related to hardware conflict. It does not often pass the self-test, that is, a crisp "beep" sound is heard, and then a blue screen occurs and the user cannot log in to Windows. This situation is generally caused by system damage, driver or hardware conflicts, viruses, etc. The solution is relatively simple. You can start with the easier and then the harder:

1. During the startup process, select "Last correct 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 by importing the backed up registry, anti-virus, and viewing the hardware device manager. Reinstall the device driver with "!"

3. It is worth mentioning that a keyboard failure or not plugged in properly can also cause a blue screen and "Keyboard error or no keaboard present" to appear. If there is no problem with the keyboard and motherboard interface, clean the keyboard connection. It can be solved by plugging it into the mouth and tightening it again.

4. The computer starts normally but there is no display. Check whether the monitor power cord, switch, and data cable are correct. It may also be that the monitor is damaged or there is a problem with the graphics card (such as dust). These can be done by observing the host condition, Startup sounds, etc. are easy to troubleshoot.

5. Reinstall the system.

6. If you still have a blue screen on startup or a blue screen during operation after reinstalling the system, it is most likely that your computer needs to be cleaned of dust. Open the case and use a hair dryer to blow off the dust from the case first, and then unplug it. For memory modules and graphics cards, use an eraser to remove the gold fingers, clean the slots, and clean the dust on the fans.

7. If none of the above can solve the problem of your computer not showing up, freezing or having a blue screen when it is turned on, then there must be a problem with one of your hardware. If it fails to pass the self-test and there is no beep, then you should first check the memory module and clean the dust; do a plug and pull test to confirm that it is not the motherboard or other other problems. Summary of boot sound judgments: Under normal circumstances, there will be a short "beep" sound when booting, which is the memory self-test sound, and then the startup screen will appear. If there is no startup screen, the computer will alarm and make a sound. Based on the length of the sound, you can determine where the computer is faulty. If there is a startup screen and you cannot enter the system, there is something wrong with the system. 1 short: The system starts normally. Congratulations, there is nothing wrong with your machine. 2 short: General error, please enter CMOS Setup and reset the incorrect options. 1 long 1 short: RAM or motherboard error. Try changing the memory. If it still doesn't work, you have to replace the motherboard. 1 long 2 short: Monitor or graphics card error. 1 long 3 short: keyboard controller error. Check the motherboard. 1 long 9 short: The motherboard Flash RAM or EPROM is wrong, and the BIOS is damaged. Try changing the Flash RAM. Constant beeping (long beep): The memory module is not inserted tightly or is damaged. Reinsert the memory module. If it still doesn't work, you can only replace one memory module. Repeated short beeps: There is a problem with the power supply. No sound or display: There is a problem with the power supply. Uncommon reason, the computer is too old
