Why does the computer suddenly restart with a blue screen, the resolution becomes low and I can t ad

Restart the computer, press F8 to select safe mode to enter the system, and see if there is one in the device manager. Or! If you don't restart the computer and choose to enter the normal mode, it should generally be fine.

If there is a belt? Or! device, you can delete it, restart the computer, and let the system automatically install the driver for this device.

There are several reasons why your computer may have a low resolution after it restarts:

1.Driver issues: After a reboot, there may be a problem with the device driver that prevents the operating system from correctly recognizing and configuring the monitor's resolution.

In this case, you can try updating or reinstalling the graphics drivers, or use the automatic driver update feature of the operating system to resolve the issue.

When you restart your PC, it might revert to the default or lower resolution. You can manually adjust the resolution through the graphics card settings screen or the display settings of your operating system.

3.Operating system updates: Sometimes, macros allow certain settings to be reset when the operating system is updated, including the monitor's resolution setting. You can check the resolution in the display settings of your operating system and adjust it to the desired value.

4.Hardware issues: In rare cases, a decrease in resolution may be due to a problem with the display itself or the connecting cables. You can try checking if the monitor connection is loose, replacing the connection cable, or testing the monitor on a different device to determine what the problem is.

If the above methods don't resolve the issue, you may need to contact your computer manufacturer or seek technical support for further assistance.

After restarting, the image is blurry, the resolution can't be 640 480, look at this, 2, the problem is the same as me, the graphics card was deleted by mistake, and the graphics card driver was installed. If you buy a computer, you will automatically search for the installation of a disk.

1. If there is a problem with the desktop resolution, reset it.

3. The graphics card is damaged, and the driver cannot be used due to the damage of the graphics card, which needs to be repaired.

This is the exact location, and it is okay not to type all of them to find "defaultsettings", so as not to be very troublesome in the future. The default value is the horizontal resolution, default

The value is vertical resolution) Once you find the key-value name, double-click on the default data entry, select the "Decimal" radio button, change the number to 800, and then below it the default

entry, the same method changed to 600. (These are the most initial resolutions and are supported by almost any screen). I guess that's OK. Hope it helps you o(o
