Common troubleshooting for installing video driver drivers

1, the problem of graphics driver failure

Q: After reinstalling the operating system, I found a yellow question mark before the video controller (VGA compatible) in "Other Devices" in "Hardware Device Manager". Students say this is because the video card does not have the driver installed, but my motherboard and video card is integrated, do not know the model of integrated graphics.

I used the Everest software to test the graphics card model but couldn't detect it. Later found the motherboard manual, which says that using the Via K8M400 chipset, where can I download the chipset's graphics driver?

A: This is a classic problem, some hardware because it is too old to identify the motherboard, but know the motherboard chipset model, then the driver is not a problem.

2. No display on boot

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).

3, display the flower screen, cannot see clearly the handwriting

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.

Color is not displayed properly, this type of failure generally has the following reasons:

1). Bad contact between display card and monitor 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, this kind of phenomenon is generally due to the magnetic properties of the object too close to the cause, after magnetization may be caused by the display screen deflection phenomenon.

4, freezing

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.

5. 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. You need to clean the are finger parts or replace the video card.

6. Missing Graphics driver

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.

7, the video card driver caused by the restart failure

This could be after installing Windows XP, not using its own graphics driver, but reinstalling the graphics driver on the hard drive, because this driver is dedicated to Windows 2000, and I think Windows 2000 and Windows XP is a 32-bit operating system based on the NT kernel. And some of the articles, when some graphics card can not find the Windows XP-specific driver, you may try to use Windows 2000/nt instead, after I use the most of the programs and games, but ultimately due to some small differences in the drive caused by the above failure. It appears that installing the graphics driver should also be the remedy!

8, install the video card and modem driver after installing the sound card driver crashes

This is due to the conflict between the modem and the video card. The sound card should work properly before installing the modem driver. If the problem still cannot be solved, you can first hit the boot box, the built-in modem from the motherboard to unplug, and then install the WINDOWS98 operating system, and then install the video card, sound card driver. Then exit the operating system and shutdown, plug the modem into the motherboard, restart the computer, the system will be prompted to find new hardware, according to the prompts to install the modem driver, and finally restart the computer.

9, after the normal installation of the graphics driver, the resolution can only be adjusted to 640x480, why?

This may be caused by incorrect installation of the driver for the monitor in the Windows 2000 operating system. The resolution steps are:

(1) Right-click the desktop, select the "Properties" option from the popup shortcut menu, and in the "Settings" tab of the Pop-up Properties dialog box, click the "Advanced" button.

(2) Click the Properties button on the Monitor tab, click the Update Driver button in the Driver tab of the popup dialog box, and follow the prompts in the wizard dialog box that appears to step into installing the driver.

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.
