Until recently I didn't even know why my graphics card lost its signal. I accidentally saw that when I turn on the table lamp, the graphic loses its signal. The table lamp normally has a neon bulb and its own power supply. Of course, it happens that the signal is lost even when I do not turn off or turn on the lamp. But the signal is always lost when I turn on the lamp ??? It's a low-power 11 watt lamp and it's just amazing to me that the card could be affected by some current induction. If induction exists at all and if it causes a problem. Certainly, it is very frustrating what is happening. to note that the computer continues to work, a tone is heard, I can even turn it off normally using a keyboard.
