30 points for help My machine used to play games without a screen screen Now when playing games it i

First rule out whether it is the display itself, then rule out driver and system problems, and finally consider the graphics card.

Update the driver. Clean the dust off the graphics card and blow it on the card with a fan. Then play the game again.

If flowers. The graphics card is broken! Change!

The probability of having a problem with the graphics card is relatively large, you first see if the graphics card fan is working normally, the temperature is too high, it will cause the screen to blur, if it still doesn't work, just change the graphics card and try it.

Disassemble the case to see if the graphics card fan is broken, it is likely that the temperature is too high to cause the screen.

The graphics card is broken, get a new one, GT240 is good, 500 yuan.

The replaceable graphics card is dual 512, and after that, the memory is also replaced with a 1G DDR2-800, which may be a matter of the picture tube.

The graphics card is aging, just replace it.

One. directx .DirectX is Microsoft's interface software developed specifically for gaming and entertainment.

Many games currently require a DirectX version ofMicrosoft Microsoft DirectX latest official multilingual version for Win9X Me 2000 XP 2003 (released on October 4, 2005).This release is intended for both developers and end users.

Two. 1.Set the BIOS to factory defaults.

2. Remove the memory, use the eraser gold finger, clean the memory slot of the motherboard, and plug it in; Increase the setting of virtual memory, and set the virtual memory to a partition with a large space outside the C drive.

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

4. Check whether there is any problem with the monitor, plug in the data connection of the monitor with the graphics card, and tighten the screws.

5. Check the heat dissipation of the CPU and graphics card, dust and oil the fan, or replace the fan. A temporary fan is added to the desktop chassis to assist in heat dissipation, and a cooling pad is added to the base.

6. Reduce resolution (800 600), color quality (16) and refresh rate; Lower Hardware Acceleration - Desktop Properties - Settings - Advanced - Troubleshoot - Drop "Hardware Acceleration" to "None" or Moderate.

8. Optimize visual effects. Right-click on "My Computer" - "Properties" - "Advanced", in the "Performance" bar, click "Settings" - Visual Effects, adjust to the best performance, or keep only some necessary items.

9. Set the desktop and screensaver to none, and do not exceed 10 desktop icons.

10. If the video memory is damaged, it is recommended to send it for repair and replace it with a graphics card.

11. The motherboard is broken.

Questioner's evaluation of the answer:

Reasons for the screen of the computer:

1.Caused by incompatibility between the graphics card driver and the system, 2Poor contact of the display line, irregular occurrence of the computer screen phenomenon, or the failure disappears after tapping and pressing the keyboard surface, which is often the result of poor contact between the LCD signal line and the interface.

3.If the graphics card is damaged or overclocked, after opening the overclocking software, if the video memory frequency exceeds the head, it is normal for the picture to have a texture error and a blurred screen, and it will also cause a crash in serious cases.

Computer Blur Screen Solution:

Kingsoft Guardian provides computer screen patches.

1.Use Kingsoft Guardian to update your graphics card driver. Open Kingsoft Guardian and enter the "Installation Wizard Tab" - click the button "Installation Driver".

2.Enter the "Reinstall System" interface, and it will automatically remind you that the driver can be upgraded to the version certified by the Microsoft logo; If you don't want to upgrade and don't want to be prompted to upgrade again, you can click "Don't prompt again". To restore the upgrade prompt, click "No longer prompt for upgraded drivers" to restore the prompt.

Something went wrong with the computer, and so did mine. Whether it is crossing or Tianlong Babu, it is all screened. It's useless to re-do it, rely on 、、、

Guess there could be two reasons:

1. The game you play is not compatible with your current system, for example, win7 can't directly play violent motorcycle games, and you need the next plug-in.

2. Your graphics card driver and graphics card do not match, it is recommended that the next driver life, update the driver to try, it is best to choose the official driver when updating, unless you are playing a very new game, otherwise the latest driver may not be very stable.

Computer problems, just take it and fix it.

It should be the reason for the display, you go check it out.

In terms of compatibility, there should be no problem, but there is only one graphics card for the blurred screen problem, and the problem types are general: poor heat dissipation, incompatibility between the graphics card and the motherboard, and driver problems.

The first two are more complicated and will be put aside. I see that your Luneng master, there is an update in the graphics card driver, you click Update to see.

The graphics card of the 640 is an entry-level graphics card, and the requirements are not too high.

Look at you like this, there should be a problem with the graphics card.

It could be a driver issue, or it could be a hardware issue.

Anyway, uninstall the driver first, go to the official website, install it yourself, and take a look.

According to your description, if you can play before, the configuration is fine.

It doesn't matter if you've fallen before! That's for sure.

You don't say anything else with the computer, it should be no problem, you can play for a few minutes, and it's a slow flower.

Accordingly. 1 is that a small number of chips in memory or video memory are broken, so that when the usage is high, there will be insufficient memory or video memory, you can use different software to run the test to test whether it is a problem with memory or video memory.

2. Due to which part is caused by overheating in use.

Turn on the chassis and check if all the fans are normal.

3. It's just that there is a problem with this game, a software problem.

You can try it yourself to rule it out.

Let me break it down.

1. This is directly related to the graphics card (it may be a driver problem or a poor contact with the graphics card).

2. The configuration is low and does not support high resolution.

Carefully check whether there is any poor contact between the graphics card slot and the graphics card, and whether there are foreign objects in the graphics card slot.

There will definitely be no blurred screen due to the small video memory, and the biggest reason is that the graphics card does not support high resolution.

If you run the game at a low resolution, see if there is a blurred screen, if not, it is said that the card performance is obviously poor and does not support high resolution, which requires a replacement of high-performance graphics cards.

If none of the above solves the problem, it is estimated that one of the parts plugged into the motherboard is not in good contact with the motherboard (you can try to replug all the parts once).

There is also a possibility that the heat dissipation of the graphics card is in trouble.

Because the system will increase the heat generated during the game, try to eliminate the heat dissipation problem. Due to poor heat dissipation of the case, the screen is blurred due to the increase in the temperature of the graphics card.

The solution is to eliminate heat dissipation issues.

It is caused by the graphics card or monitor not supporting high resolution.

Solution: (1) Restart the computer, press the F8 key continuously, pop up the advanced boot menu, select enter to enter the "Safe Mode" to log in to the system, then enter the display settings under Windows, select the 16-color state, click the "Apply" button, and click the "OK" button.

2) Restart the computer, in Windows normal mode, enter the Device Manager, delete the graphics card driver, and restart the computer.

You can follow the following tips for burying you, I hope mine is helpful to you! ~

Cause Analysis]:

The graphics card driver is abnormal.

The directx program is abnormal.

DirectX" and follow the prompts to install it.

Solution 3: Check whether the hardware temperature is normal.

1.Open the 360 security guard, and find "Master Lu" in the "Function Collection" on the right side, if you don't have it, you can add it in the "Unadded Functions".

On the homepage of Master Lu, observe the hardware problem on the right side after its automatic detection is completed, as shown in the following figure:

3.If the standard branch is red, it is recommended that you visit 360.com to select your area, query the merchants close to you to detect hardware conflicts, dust removal and heat dissipation, etc., and you can also communicate with the merchants to provide door-to-door services.
