If you think this operation is too troublesome, reboot the system directly. If this is still the case, the above actions still do not work, and the system needs to be repaired or even reinstalled.

This situation is generally caused by the operating system not loading normally, restart the computer to try, if it still can't be solved, reinstall or restore the system.

Indicates that the system load was not successful, if the reboot is the same, considering the system is damaged, you need to reinstall the operating system.

This is the "blue screen"!If restarting the system still doesn't work, you may need to do a new system solution!

If you don't react when you move the mouse, it's a crash.,Maybe there are too many startup items at boot.,There are conflicts.,It should be good to restart it.。

I've encountered problems with settings but I forgot how to get it and don't play it often.

First, the cause of the failure.

If the word "nosignal" disappears after only a few seconds, it is most likely that the memory module is not properly featured, or that the memory module is not plugged in properly, or that there is too much dust in the memory slot.

The word "nosignal" is on the screen, and this type of failure is characterized by the fact that the word "nosignal" is displayed until the shutdown or restart, indicating that the fault is no longer a display, but:

1. Graphics card: Generally, the main control chip of the graphics card has poor characteristics, or the contact with the graphics card slot is not close, or there is too much dust in the graphics card slot.

2. Motherboard: Generally, the power dissipation of the on-board power circuit decreases, which makes the power supply of the graphics card insufficient, and the filter capacitor in the on-board power circuit seriously leaks, resulting in a decrease in the voltage of the corresponding power supply circuit.

3. The data cable characteristics are poor, or the contact with the graphics card and display is not close.

Second, the solution.

Open the case, remove the graphics card, and erase it with an eraser. Finally, don't forget to clean the slots with a brush. Because today's graphics cards generally come with their own fans, it is easy to accumulate dust, so just clean it up.
