A white screen suddenly appears on my computer, how to solve it?

I was playing well on my computer and suddenly the screen went blank. What should I do?

1) When your computer screen goes blank, what are you doing on the computer? Can you tell me? I will answer you more accurately based on what you said.

White screen is usually caused by incorrect operation, so we should remember some operations that easily cause white screen and try to avoid it. First of all, do not let your computer run at full capacity, such as playing games, watching videos, downloading files, and browsing the web at the same time. Such multiple operations can easily lead to crashes and white screens. Therefore, when playing games, watching videos, downloading files, and browsing the web, it is best not to perform other operations at the same time.

No matter what you are doing, as soon as there are signs of lag, stop the current operation and exit the application immediately. This prevents the screen from turning white. If the problem persists, it is recommended to stop using or temporarily stop watching.

Hardware: If the memory capacity is small, please consider adding a memory module. In addition, you also need to check whether the hard disk has bad sectors and whether there are incompatibilities or malfunctions in the hardware. It is recommended to use Master Lu to test the temperature of hardware such as CPU to ensure that it is not too high.

White screens are often caused by incorrect computer operations, and lagging is the root cause of white screens. As long as you avoid stuck operations, you can reduce or avoid white screens.

2) If the white screen turns on, is it related to your improper operation before shutting down? For example: playing games, watching videos, operating large things, using the computer for a long time caused by card? Or you downloaded something inappropriate, and the fault doesn't happen for no reason, right (if it's caused by this problem, just make sure your computer doesn't get stuck, have a blue screen, or suddenly shut down, and it won't be like this when you start it up)?

Indeed, if you are unable to reinstall the system yourself, it is recommended that you seek help from maintenance personnel. If you have tried various methods and still cannot turn on the computer, the disk may be damaged due to a sudden shutdown. You can try taking out the motherboard battery to let it charge, or leave it for a while and try to turn it on again. If the problem persists, it is recommended that you go to a repair shop to repair it.

One is to leave it for half a day or a day and sometimes it will recover on its own, and the other is to reinstall the system.

As long as you pay attention to your computer not to freeze, blue screen, or suddenly shut down, it will not be like this when you start it up.

If you have any questions, please ask me.

The desktop switches to the game card and the screen goes blank for a second

A computer uses Intel 810 motherboard and Windows 98 operating system. Recently, I found that in some

When the mouse pointer is moved quickly in the window, blank spaces appear.

analyze

Mainly caused by the DMA buffer reserved by the "Direct Memory Access Controller" being too small.

Exclusion process

After determining the cause of the fault, the troubleshooting process is as follows.

(1) Right-click the "My Computer" icon, select the "Properties" command in the shortcut menu, and open the "System Properties" dialog

frame. Switch to the "Device Manager" tab and select "Direct Memory Access Control

under the "System Devices" option in the list

Controller" option, as shown in 4-21.

(2) Click the "Properties" button to open the "Direct Memory Access Controller Properties" dialog box. Switch to "Settings" and select

tab, select the "Reserve DMA Buffer" check box in the "Reserve Memory" option group, and increase the DMA buffer,

Set reserved bytes to 64 KB.

(3) Click the "OK" button continuously to save the settings and troubleshoot.

Why is the computer stuck and the mouse has a white screen on the desktop?

How to use the computer to freeze or freeze as follows:

1. The CPU load is too large, or it is not working properly. Check the heat dissipation of the CPU and graphics card, remove dust, oil, or replace the fans.

2. The power supply voltage is unstable and the power supply power is insufficient. Replace the power supply with a high-quality, high-power one.

3. Clean the disk frequently and defragment the disk.

1. In the "My Computer" window, right-click the drive letter you want to clean - "Properties" - "Clean Disk" - check the files you want to delete - OK - Yes.

2. Clear temporary files, start - run - enter "%temp%" - OK.

3. Use Optimization Master or Super Rabbit to clean the registry and junk files.

4. Close some startup programs, start-run-msconfig---start. Except for anti-virus software and input methods, general programs can be closed.

5. Delete unused program software.

6. Defragment the disk--Start--All Programs--Accessories--System Tools--Disk Defragmenter--Selected Disk--Analysis--Defragmentation.

7. Reduce the memory burden and do not open too many programs. If there are too many documents opened at the same time or too many programs running, there will not be enough memory to run other programs, and unused programs and windows must be closed at any time.

4. Upgrade the graphics card and network card driver, and change to a higher-grade graphics card.

5. Increase the physical memory. Now the memory is generally at least 2G.

6. Set up virtual memory reasonably.

1. When playing games, the virtual memory can be set larger. The maximum and minimum values ​​are set to 2-3 times of the physical memory. If it is larger, it will take up too much hard disk space.

2. The virtual memory setting method is: right-click My Computer--Properties--Advanced--Performance Settings--Advanced--Virtual Memory Change--Select the partition where the virtual memory (page file) is stored in the drive list- -Custom size--Set values ​​in "Initial size" and "Maximum value", then click the "Set" button, and finally click the "OK" button to exit.

3. The partition where the virtual memory (page file) is stored must have enough space. Insufficient hard disk resources will cause insufficient virtual memory. In a computer, setting virtual memory in one partition is enough. It is not necessary. Set up in multiple partitions.

7. Use Optimization Master, 360 or Super Rabbit to optimize your computer.

Changing the operating system is a universal method
