Display abnormality processing method

[Fault 1] Booting without display This type of fault is generally caused by poor contact between the graphics card and the motherboard or a problem with the motherboard slot. For some motherboards with integrated graphics, if the memory shared the main memory, you need to pay attention to the location of the memory stick. Generally, the memory stick should be inserted in the first memory slot, about the difference between full-width and half-width. There is no display failure due to the cause of the graphics card. Generally, a long and two short beeps will be issued after booting (for AWARD BIOS graphics cards). [Fault 2] Display color is not normal. This type of fault generally has the following reasons: 1. Poor contact between the display card and the display signal line; 2. The display itself is faulty; 3. In some software, the color is not normal when running. It is common in old-fashioned machines. There is an option to check the color in the BIOS, and it can be turned on; 4. Graphics card is damaged; 5. The display is magnetized. This type of phenomenon is generally caused by excessive proximity to a magnetic object, which may cause deflection of the display after magnetization.

[Fault 3] Display the screen, can't see the writing. This type of fault is generally caused by the high resolution of the monitor or graphics card. When the screen is displayed, you can switch the startup mode to the safe mode, and then enter the display settings under Win 98. In the 16-color state, click the “Apply” and “OK” button. Restart, delete the graphics card driver in the normal mode of Windows98 system, restart the computer. You can also enter safe mode, edit SYSTEM in pure DOS environment. INI file, will display. Drv=pnpdrver changed to display. Drv=vga. After drv, save and exit, and then update the driver in Windows. [Fault 4] This type of failure occurs when the motherboard is incompatible with the graphics card or the motherboard and the graphics card are not in good contact. The graphics card is incompatible with other expansion cards and can cause a crash. [Fault 5] The graphics card driver loses the graphics card driver loading. The driver is automatically lost after running for a period of time. This type of fault is generally caused by poor quality of the graphics card or the graphics card is not compatible with the motherboard, which makes the graphics card temperature too high, resulting in system operation. Unstable or crashes, only the graphics card is replaced at this time. In addition, there is a special case where the graphics card driver was previously loaded, but after the graphics card driver is loaded, it crashes when entering Windows. Other models of graphics cards can be replaced by inserting the old graphics card after loading its driver. If this type of failure cannot be resolved, the registry is faulty, and the registry can be restored or the operating system can be reinstalled. [Fault 6] Text and screen display are not completely resolved according to the above-mentioned flower screen scheme. If the screen can be seen clearly, just delete the graphics card driver, restart the computer, and load the graphics card driver. [Fault 7] Abnormal noise or pattern on the screen This type of fault is usually caused by a problem with the graphics card's memory or a bad contact between the graphics card and the motherboard. You need to clean the gold finger of the graphics card or replace the graphics card.
