Solution: Use an eraser to wipe the gold finger of the memory module.
and reinsert the memory module; Replace the memory module.
2. Poor contact of the graphics card.
Solution: Same as memory method.
3. The main engine is short-circuited.
Workaround: Clean up the host and replug the wiring.
4. Motherboard BIOS problems.
The motherboard BIOS stores important hardware data, and if it fails, it can cause the computer to not boot.
Solution: Go to the motherboard BIOS settings page and restore the BIOS to the default value.
5. Dust killer.
Excessive dust accumulation in the machine can also cause crashes. When it comes to circuit boards, dust is a ticking time bomb. In addition, if the floppy drive head or optical drive laser head is contaminated with too much dust, it will lead to read and write errors, and in serious cases, it will also cause computer crashes.
Therefore, it is necessary to pay attention to the dust prevention of the computer room frequently.
Precautions for computer use:
Because the monitor will generate high-voltage current to impact the hardware equipment in the host computer at the moment of power-on, it will inevitably accelerate the aging of the hardware in the long run, so the computer should turn on the power of the monitor first, and then turn it on.
If the external cat is connected to the power after entering the system, sometimes there will be a problem of not being able to connect to the Internet, but the problem can be solved after not turning off the power of the external cat and restarting the computer. Therefore, every time you turn on the device, you should first connect all commonly used peripheral devices to the power supply, and then connect the power to the host.

Anonymous users2024-02-05Summary. First: After powering on, the host is running normally, but the display screen is black and cannot be displayed.
Solution: This type of fault first detects whether the VGA cable between the host and the monitor is connected normally, and whether the power supply of the monitor is normal. If there is no problem, find a screwdriver to open the cover of the main chassis, pull off the memory module, wipe the gold finger area with an eraser, if it does not turn on, there is a separate graphics card to unplug the graphics card, if it does not turn on, it is likely that the hardware failure of the motherboard.
What is the reason why the computer won't turn on? How to deal with it.
The first type: After the boot is turned on, the host is running normally, but the black screen of the monitor cannot be displayed. Workaround:
This type of fault first detects whether the VGA cable between the host and the monitor is connected normally, and whether the power supply of the monitor is normal. If there is no problem, find a screwdriver to open the cover of the main chassis, unplug the memory module and hold it quickly, wipe the gold finger area with an eraser, if it is not turned on, Duan Ma, who has a separate graphics card, unplug the graphics card, if it is not turned on, it is likely that the hardware failure of the motherboard is very likely.
The third type: the computer can't enter the system after it is turned on, can't enter the table, and keeps getting stuck in the interface that is being started: Solution:
This kind of failure is likely to be a problem with the system before the news,First of all, after booting up, keep pressing F8,After a selection interface appears,Select the option of "last correct configuration",Restart the computer,If it still doesn't work,It may be that the system file is corrupted,Then reinstall the system。
Fourth: After booting, a cursor in the upper left corner of the display has been flashing and flashing, but it can't enter the system:Solution:
This kind of fault is sorted out by the following sequential shooting: 1. Enter the BIOS and set the hard disk to be the first boot item of Yuanhe; If not, then the second point. 2. Change the hard disk mode in BIOS; If not, the third point.
3、If there is a U disk boot disk into the PE desktop,Repair the boot file again,If it still doesn't work, reinstall the system。
If you have been self-checking and regretting it, the solution: this kind of fault means that there is a bad sector in a certain area of the hard disk, at this time, reboot the machine, and quickly press the space bar when the dust is connected to the self-test interface, which is the key that is the longest scattered brother on the keyboard, at this time, it will skip the self-test and enter the system.

It may be caused by poor contact of memory modules, power failure, and excessive dust accumulation on the computer, if it is a poor contact of memory modules, 1. Remove the screws on the back of the computer host. 2. Take down the memory module. 3. Use a brush to clean the memory module socket.
4. Install the memory module back in place. Laptop: It may be caused by a loose hard disk, a loose power supply, or a poor contact with the memory module.

Anonymous users2024-02-02Summary. What is the reason why the computer won't turn on? What to do Hello dear, happy to answer for you.
1. Poor contact, including graphics card, memory, hard disk cable, power cable, etc., clean up the dust, use an eraser to erase the gold finger of the graphics card and memory and replug it tightly. These are the most common and the easiest to solve. Clean up the dust in the chassis to improve heat dissipation and ensure the normal operation of each fan.
2. If the graphics card or memory is damaged or there is a compatibility problem with the motherboard, the replacement method will solve it. If it is multiple RAM, you can try it with one. 3. Hard disk problem, "non system disk or disk error, replace and strike any key when ready" appears when booting up" "hard disk not present "Whenever the words "disk, hdd, etc. appear", you can check from the power and data cables of the hard disk to the hard disk itself.
Hope it helps

Wait a minute. Listen to my description.
It's the keyboard when I turn it on.
The display light is not on.
Speak. Hello dear, glad to answer for you. <>
1.Check whether the connection cable of the computer is loose, and if it is loose, plug it back in and turn it on. 2.
Check whether the hard disk of the host is loose, and if it is loose, plug it back in again to boot it on. 3.Check if the memory module of the host computer is damaged, and if it is broken, you can simply replace it with a new one.
4.Connect the monitor vibrator cable to the vulnerability integrated graphics card interface on the motherboard, check whether the discrete graphics card is damaged, if the computer can be turned on, it means that the discrete graphics card is broken, it is recommended to go to a professional repair point to repair it. Hope it helps
If a computer crashes when it starts, it can be divided into two types: POST and crash when loading the operating system. The specific troubleshooting methods for crash faults during computer self-test are as follows. >>>More
There are many reasons, which should be analyzed and excluded one by one: >>>More
The laptop won't turn on.
1.The laptop power supply is low. >>>More
The computer is slow to respond, and it may be that the frequency of the CPU is too low. It is also possible that the memory is too small, and you can replace it with a larger memory. If you are watching ** or the card is slow when playing, then you also need to add 1 external graphics card with better performance to solve this problem.
In fact, there are many reasons why it can't be turned on, such as no power and memory sticks, which need to be checked one by one, if there are no problems, you need to take it to the repair shop to check.
