The problem of entering the system with a blurred screen, the boot screen can enter the system

This is because you are using two different capacities of memory, so you can unplug one of them and try to see if your graphics card connector is plugged in.

Most of them are symptoms that occur after overclocking your graphics card.

Quick troubleshooting methods for graphics card failures.

You may encounter a lot of problems with the monitor when using the computer, so let's give you some simple fault analysis.

1. There is no display when you turn on the machine.

This type of failure is usually caused by poor contact between the graphics card and the motherboard or a faulty motherboard slot. For some motherboards with integrated graphics cards, if the video memory shares the main memory, you need to pay attention to the location of the memory module, and generally there should be a memory module inserted on the first memory module slot. There is no display failure when booting due to the graphics card, and there will generally be one long and two short beeps after booting (for Award BIOS graphics cards).

2. Display the flower screen, and the handwriting is not clear.

This type of failure is usually caused by the display or graphics card not supporting high resolution. When the screen is blurred, you can switch the boot mode to safe mode, and then enter the display settings under Windows 98, and click the "Apply" and "OK" buttons in the 16-color state. Reboot, delete the graphics card driver in Windows 98 normal mode, and restart the computer.

You can also not enter the safe mode, in the pure DOS environment, the file will be changed to the back, save the disk to exit, and then update the driver in Windows.

3. The color display is abnormal.

Such failures are generally due to the following reasons:

a. Poor contact between the graphics card and the display signal line.

b. The display itself is faulty.

c. The color is not normal when running in some software, which is generally common in old-fashioned machines, and there is an option to verify the color in the BIOS, which can be turned on.

d. The graphics card is damaged.

e. The display is magnetized, which is generally caused by being too close to the object with magnetic properties, and the phenomenon of deflection of the display screen may also be caused by magnetization.

4. Crash This kind of failure is generally seen in the incompatibility between the motherboard and the graphics card or the poor contact between the motherboard and the graphics card; Incompatibility of the graphics card with other expansion cards can also cause crashes.

5. Abnormal noise or patterns appear on the screen.

This type of failure is usually caused by a problem with the graphics card's video memory or poor contact between the graphics card and the motherboard. You need to clean the gold finger of the graphics card or replace the graphics card.

6. The graphics card driver is missing.

The graphics card driver is loaded, and the driver is automatically lost after running for a period of time, this kind of failure is generally due to the poor quality of the graphics card or the graphics card is not compatible with the motherboard, which makes the graphics card too hot, resulting in unstable system operation or crash, at this time the only way to replace the graphics card.

In addition, there is a special case where the graphics driver used to be loaded, but after the graphics driver was loaded, it crashed when entering Windows. Replace the graphics card of other models and insert the old graphics card after loading its drivers. If this failure does not resolve the problem, the registry is faulty, and the registry can be restored or the operating system can be reinstalled.

1. Set the BIOS to the factory default;

2. Remove the memory with an eraser gold finger, clean the memory slot of the motherboard, plug it in now, and remove the memory suspected of being problematic; Increase the setting of virtual memory, and at the same time set the virtual memory to the partition with large hard disk space;

3. It is an independent graphics card, remove the graphics card, wipe the gold finger, clean the slot, install it again, and plug it tightly;

4. Use the exchange method to try whether there is a problem with the display to repair or replace the display; Check that the display data cable is connected to the graphics card, plug it in, and tighten the screws;

5. Check the heat dissipation of the CPU and graphics card, dust and oil the fan or replace the fan;

6. Reduce resolution, color quality and refresh rate; Reduce hardware acceleration desktop properties, settings, advanced, troubleshooting, and reduce hardware acceleration to keyless smart change or moderate.

7. Upgrade the graphics card driver;

8. Optimize the visual effect, right-click the "Advanced" attribute of "My Computer", and in the "Performance" column, click "Set the Hunger" and "Visual Effect" to adjust the best judgment performance;

9. If the graphics card memory is damaged, it is recommended to send it for repair and replace it with a high-grade graphics card;

10. If the motherboard fails, repair or replace the motherboard;

11. Insufficient power supply may also cause a blurred screen, and replace it with a high-power power supply;

12. If you are hit by a Trojan virus, enter the safe mode to fully kill the virus.

1. External interference, such as electric sparks or high-frequency electromagnetic interference near the use site of the display, this interference will cause the display screen of the display to produce white horizontal stripes. Solution: Avoid using the monitor in this situation;

2. Internal interference, this interference will make the display screen of the display appear black horizontal stripes, in this case, you can open the case to check whether there is a poor contact inside the display, whether there is a problem with the output end of the power supply or the output transformer, etc., because the reasons for this situation involve more professional technology, so it is best to ask a professional to repair it.

2. Improper display resolution setting causes blurred screens.

When the monitor is set incorrectly in Win and Win95, there may be a blurred screen failure when starting Windows, that is, the picture is layered, shaky, serious and even black screen of death. Solution: Enter the setup of win or enter the security mode of win95, and reset the display mode of the display.

Third, the graphics card and the Chinese system conflict In this case, when exiting the Chinese system, a blurred screen will appear, and there will be no response to random keystrokes, similar to a crash. Method: Enter at this time"mode c080"can be resolved.

Fourth, the main control chip of the graphics card has poor heat dissipation effect This will also produce the phenomenon of blurred screen failure. Solution: Improve the heat dissipation performance of the graphics card.

5. The video memory speed is too low When the video memory speed is too low to match the speed of the host, the screen will also be blurred. Solution: Replace the video memory with a higher speed, or reduce the speed of the host.

6. Video memory is damaged When the video memory is damaged, there will be a phenomenon of blurred screen and confused characters when the system starts. Solution: The memory card must be replaced.

7. Viral Causes Some viruses can also appear during the outbreak of flowers. Solution: Use anti-virus software to eliminate it.

The screen of the computer is one of the more common problems when using the computer, and there are many reasons for the screen of the computer, which may be a hardware problem or a system problem.

If it is normal, it means that it is a driver problem of the graphics card, you can update the driver of the graphics card to try. If it is abnormal, the screen is broken or the screen cable is faulty. It is recommended to go to the service center for testing.

Graphics card screen is a relatively common display failure, most of the graphics card screen failure is caused by the graphics card itself, the following solutions may be helpful to you.

If the screen is blurred as soon as the display is turned on, first check the heat dissipation of the graphics card, touch the temperature of the graphics memory chip with your hand, and check whether the fan of the graphics card is stopped. Then look at the AGP slot on the motherboard to see if there is any dust, check whether the gold finger of the graphics card is oxidized, and then clean up the dust according to the specific situation, wipe the gold finger with an eraser to polish the oxidized part. If there is a problem with heat dissipation, change the fan or install a heatsink on the video memory.

Or go into the BIOS and see if the voltage of the AGP is stable nearby.

Reinstall the graphics card driver, if it affects your operation, and it's not too troublesome, reinstall a system to try, I hope it can help you.

There are many reasons for this problem:

1. If you have a problem with the driver of the graphics card or motherboard, you can update the driver (it is recommended to use the disc that you brought when you bought the computer, if not, use the driver life or the driver wizard).

2. System problem: change the system and reinstall it.

3. If the contact of the graphics card is not good, dial the graphics card and use the eraser to remove the gold finger and plug it back in.

4. If the power supply of the motherboard or graphics card is insufficient, the power supply with a higher rated power can be replaced.

5. The graphics card is old, observe whether the capacitors on the graphics card are bursting or bursting, if there is, send it to the computer for repair, and replace it, which is very cheap.
