The computer fails to transmit the signal to the screen, input devices, and mouse.
I mistakenly powered off my PC using the button on the case. Now, when I turn it on, the fans start spinning and the lights flash, but the display isn’t getting a signal and the mouse and keyboard aren’t responding either. I’ve verified all cables are properly connected. This issue has happened before; I resolved it by swapping out the case and relocating all components to the new one. That change seemed to fix it somehow. I’m considering taking apart the old case, reinstalling everything, and seeing if that works.
Attempting a power reset or shutdown for my Wi-Fi adapter. The device stopped working until I tried this method, and it now functions properly. I've included the YouTube link for your reference.
