As a job chosen by the day, I believe I have to deal with computers every day, and it is common to encounter some computer strikes.
Computer boot failure also occurs the most frequently, specifically manifested as computer poisoning, Windows registry destruction, no display on the computer, and the motherboard cannot be recognized.
Today, Jijie will teach you how to solve several types of faults that occur when the computer is turned on.
1, no display on the computer
This situation is manifested as the indicator light is on after booting, but the screen does not display. In other words, the computer is in a state of black or blue screen.
You need to check whether the motherboard is burned in time, and then check whether the data on the hard disk is intact. If it is damaged, replace it in time.
2, frequent crashes
If there is a crash, it may be that there is a problem with the motherboard CPU, and you need to replace CPU. If you are in a dead state for a long time, you need to touch whether the surrounding CPU is hot. If the temperature is very high, you need to replace the fan.
3. Display the screen, and the words cannot be seen clearly
If the screen appears, it may be caused by problems with the graphics card and does not support high score rates. When powering on, switch the startup mode, select safe mode , and then select the correct installation mode in the 16-color state and select Restart.
If you cannot enter safe mode, you can only edit the corresponding digital code in DOS mode to re-drive the program to see if it can be fixed.
4. The motherboard port fails
Another situation is that the motherboard port fails. At this time, the corresponding prompt will be displayed on the main page. You need to check whether the COM port that comes with the motherboard can be used normally.
5. The color display is abnormal
This may be due to the poor contact between graphics card and the graphics card signaler. You can remove the graphics card of the computer, clean it up and then reinstall it. If not, it means the graphics card is damaged and needs to be replaced in time.
6, computer poisoning
If the computer frequently crashes or the file is deleted, the program is too slow when used, which is also a manifestation of viruses in the computer.
As long as you install antivirus software, clean up the virus in time and delete some damaged files.
