A lot of people who are not proficient in computers are generally afraid of graphics cards, such as CPU problems, but the graphics card out of the problem is trembling. Well, actually, this type of failure is usually caused by faulty graphics card contact with the motherboard or problems with the motherboard slots. For some integrated graphics boards, if the video memory sharing main memory, you need to pay attention to the location of the memory bar, generally in the first memory slot should be inserted in the memory bar. Due to the video card caused by the boot-free display failure, the boot will normally emit a long two short beeps (for award BIOS graphics card).
Common fault 1: Panic
This type of failure is generally seen in the motherboard and the video card is not compatible with the motherboard and graphics card contact is not compatible with other expansion cards will cause panic.
Common fault 2: abnormal clutter or patterns on the screen
This type of failure is usually due to video card memory problems or graphics card and the motherboard contact caused by bad. Need to clean the Kakin finger parts or replace the video card.
Common Failure 3: Graphics driver missing
Graphics driver loading, running for a period of time after the driver automatically lost, such failures are generally due to poor graphics card quality or graphics card and the motherboard is not compatible, so that the video card temperature is too high, resulting in the system running unstable or panic, at this time only the replacement video card.
In addition, there is a special case in which the graphics driver was previously loaded, but there was a panic when you entered Windows after the graphics driver loaded. Other types of graphics cards can be replaced after loading their drivers, insert the old video card to resolve. If this type of failure is not resolved, the registry fails, the registry is restored, or the operating system is reinstalled.
Common fault 4: Display the flower screen, can not see clear handwriting
This type of failure is typically caused by a display or video card that does not support high resolution. Switch boot mode to Safe mode when Huati, and then enter the display settings under Windows 98 and click the "Apply" and "OK" button in the 16-color state. Reboot to remove the graphics driver in normal mode in Windows 98 system and restart the computer. Also can not enter Safe mode, in pure DOS environment, edit System.ini file, will display.drv=pnpdrver to Display.drv=vga.drv, save to exit, and then update the driver in Windows.
Common fault 5: color display is not normal, such failures generally have the following reasons:
1. Display card and monitor signal line contact bad
2. Monitor own fault
3. In some software run when the color is not normal, generally common in the old machine, in the BIOS has a check color options, it can be opened
4. Video card damage;
5. The display is magnetized, such a phenomenon is generally due to the magnetic properties of the object is too close to the result, magnetization may also cause the display screen deflection phenomenon.
