Common faults and solutions of graphics card

This type of failure is typically caused by bad contact with the motherboard or a problem with the motherboard slot. For some motherboards with integrated graphics, if the memory is shared with the main memory, you need to pay attention to the location of the RAM, generally in the first memory slot should be inserted in the memory bar. Due to the video card cause of no display failure, usually after the boot issued a long two short beeps (for award BIOS graphics).

Common faults two: Display the flower screen, cannot see the handwriting clearly

This type of failure is typically caused by a display or video card that does not support high resolution. When huaping, switch the boot mode to Safe mode, then enter the display settings under Windows 98 and click the "Apply", "OK" button in the 16-color state. Restart, delete the graphics driver in normal mode in Windows 98, and restart the computer. can also not enter the security mode, in the Pure DOS environment, edit the System.ini file, the display.drv=pnpdrver changed to Display.drv=vga.drv, save the exit, and then update the driver in Windows.

Common fault Three: color display is not normal, such a failure generally for the following reasons:

1. Bad contact between the display card and the display signal line

2. Monitor itself failure

3. In some software running color is not normal, generally common in the old machine, in the BIOS has a check color option, turn it on

4. The graphics card is damaged;

5. The display is magnetized, such phenomenon is generally due to the magnetic properties of the object is too close to the cause, after magnetization may also be caused by the display screen deflection phenomenon.

Common trouble Four: the crash

This type of failure generally occurs when the motherboard is incompatible with the video card or the motherboard is not in contact with the graphics card, and the video card incompatible with other expansion cards can also cause the crash.

Common trouble Five: abnormal clutter or pattern on the screen.

This type of failure is generally due to video card memory problems or bad contact with the motherboard card. Need to clean the are finger part or replace the display

Card.

Common Failure VI: Graphics driver missing

Graphics driver loading, after running for a period of time the driver is automatically lost, such a failure is generally due to poor graphics card quality or the video card is incompatible with the motherboard, so that the video card temperature is too high, causing the system to run unstable or panic, the only time to replace the video card.

In addition, there is a special case where the graphics driver was previously loaded, but crashes when entering windows after the graphics driver is loaded. Replacement of other models of the video card after loading its driver, 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.
