There are several reasons and solutions for the sudden occurrence of the screen of death on the win7

There is no way to crash, only press the power on and off button to turn on the machine, if it is always like this, look at the following method.

1. The antivirus software is installed more, and all the monitoring is turned on, less monitoring is turned on or not monitored, and the virus is often checked and killed.

2. The software or driver is not compatible with the system, reinstall or upgrade the driver.

4. Memory, graphics card, and voltage instability can also cause crashes (if the memory is too small, add a memory module).

5. The temperature of common hardware such as CPU or graphics card is too high, which is most likely to cause card and crash.

6. If the hard disk has bad sectors, use software to repair the bad sectors of the hard disk, format the hard disk, repartition and reinstall the hard disk, and replace the hard disk.

7. Upgrading the hardware causes an incompatible crash.

8. Too many junk files, too many disk fragments, etc.

9. If it always doesn't work, it is recommended to overhaul it.

Use the system that comes with the system restore method:

The system comes with the system restore: "Start" "Programs" "Accessories" "System Tools" "System Restore", click "Restore my computer to an earlier time", press Next, you will see that the date page has a dark date, that is the restore point, after you select, click Next to restore (win7 restore the system, in the control panel then the device and security sub-option and then the backup and restore sub-option).

The computer should not operate at full capacity, that is, when playing games, watching **, and watching web pages, it is most likely to crash and blue screen while doing other operations, so don't operate other things when playing games, watching**, and watching web pages.

If your memory is small, it is recommended to add a memory module to test whether the temperature of your CPU and other hardware is high. The other is whether there is a problem with the hard disk.

Do you know what are the reasons for the blurred screen of the computer?

1. The main reasons for the screen of death are the following memory reasons. Why does memory cause a blurred screen? Because integrated motherboards usually integrate the display engine inside the chipset's northbridge chip, a part of the physical memory is used as the video memory.

And if the video memory that can be shared by the integrated graphics card is too low, it will lead to a screen of death. Solution: Expand memory.

If it's just an office computer, 2G of RAM is generally enough. If you want to play large-scale online games, you need at least 4G of RAM, or even 8G. In addition, poor contact of the memory module may also lead to a blurred screen, you can remove the memory module and wipe the gold finger with an eraser to wipe off the oxide layer.

2. The reason for temperature. The temperature of the north bridge of the integrated motherboard is too high, which will also lead to a blurred screen, because the graphics card is integrated in this, and you can artificially add a fan to see if it can be alleviated.

3. The reason for the drive. This is also an important reason for the blurred screen, which mostly occurs after changing the driver version of the graphics card, and may also be caused by the corruption of the driver file. The solution is very simple, reinstall the graphics card driver, and the version does not have to be blindly new.

The first thing to check when the screen is blurred is the graphics card driver, which conforms to the principle of soft first and then hard.

4. The reason for the graphics card. There are many reasons for this. It is possible that the BIOS of the graphics card is defective, and this can be solved by flashing VGABIOS; It is also possible that the video memory is damaged or aged, which is a relatively common situation, so you can only buy a discrete graphics card to solve the problem.

Blurred screen on Win7 computers is a common problem that can be caused by hardware failures, driver issues, or operating system errors. Here are three common fixes::

First of all, you should check if your computer's hardware is working properly. You can try the following steps:

Check that the connection cable of your computer monitor is loose or damaged, and try to reconnect or replace the cable.

Clean the interface between the monitor and the graphics card to make sure the connection is working properly.

Try connecting your PC to another monitor, and if the problem is resolved, it may be a display malfunction.

Outdated or incompatible graphics drivers can cause screen blur issues. You can update your drivers by following these steps:

Open"Device Manager"and find it"Display adapter", the option.

Right-click on the name of the graphics card and select"Update the driver software"。

Restart your computer and see if the problem is resolved.

If the above methods do not solve the problem, it may be that there is an error in the operating system that causes the screen to blur. You can try the following steps to fix operating system errors:

Open"Control Panel", select"Systems and security", click Lead Min"Recovery"。

, select"System Restore"and follow the wizard to select a recovery point and restore the system state at that point in time.

If System Restore doesn't work, you may want to consider reinstalling the operating system.

Please note that it is advisable to back up important files and data to avoid loss before performing any repair operations.
