Summary of common troubleshooting solutions for notebook video cards

Failure 1, graphics driver missing

Graphics driver loading, running for a period of time after the driver automatically lost, generally due to poor graphics card quality or graphics card incompatible with the motherboard, so that the graphics card temperature is too high, resulting in the system running unstable or panic, at this time only the replacement of the video card can solve the problem.

Failure 2, no display on the boot

This failure is typically caused by faulty graphics card contact with the motherboard or problems with the motherboard slot. For some integrated graphics card board, 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 of the card due to the cause of the boot without display fault, Typically emits a long, two-short beep (for award BIOS video card).

Failure 3, computer crash

This type of failure is generally seen in the motherboard and the graphics card is incompatible with the motherboard and the graphics card contact is not compatible with the card and other expansion cards will cause panic.

Failure 4, monitor display color is not normal

The reasons for such failure are: 1, the monitor itself failure; 2, display card and monitor signal line contact is bad; 3, in some software running time color is not normal, generally common in the old fashioned machine, in the BIOS has a check color option, it can be opened; 4, the Monitor is magnetized; 5, the video card is damaged, This kind of phenomenon is generally due to a magnetic object too close to the cause, magnetization may also be caused by the display screen deflection phenomenon, you can replace the video card.

Fault 5, abnormal clutter or pattern on the screen.

This type of failure is generally due to video card memory problems or video card and motherboard contact caused by the need to clean the Kakin finger parts or replace the video card.

Malfunction 6, display the flower screen, can't see the handwriting clearly

This is generally because the monitor or video card does not support high resolution, the flower screen can switch to boot mode to Safe mode, and then under the Win98 into the display settings, in 16-color state click "Apply" and then click "OK" button. Reboot, delete the graphics driver in normal mode of WINDOWS98 system, and restart the computer. Of course, can not enter the Safe mode, in a pure DOS environment, edit System.ini file, the display.drv=pnpdrver changed to Display.drv=vga.drv, save the exit, and then update the driver in Windows.
