Plug in the power supply screen, does the graphics card screen have anything to do with the power su

Please reinstall the graphics card driver first to see if it can be solved, in this case, the power supply is bad, and the output ripple voltage is more likely to be high, so it is recommended to replace the power supply.

Of course, if you understand electronic technology, you can measure whether the output voltage is stable, and if it is stable, you can add several filter capacitors to the output line to try (you don't have to change the power supply after adding filter capacitors).

In the words of the downstairs: Safe mode is used without the graphics card enabled.

I think the graphics card is okay because it's normal when you're running battery power. If there is a problem with the graphics card, there is no battery power supply. Yes, it's normal in safe mode, that's because a lot of programs don't start in safe mode, so the power supply interferes with it very little.

With the increase of the startup program, the output power of the power supply is not the same, the greater the power, the greater the ripple, that is to say, the greater the impact of the power supply.

The biggest possibility is that the graphics card driver is wrong, and the second is that there is a problem with the graphics card!
