I was starting the CPU of my PC as usual I do on other days. But by chance, it gave a false start. I mean, the UPS made a sound, the sound indication of power failure, but there was not any, only the monitor had started, but booting has not started. Then, I pressed the CPU power button, and the CPU started as normally with Windows booting operations running. After that, the Windows start screen showed up normally as usual with all operations running smoothly. My query is, why this has happened? Is my PC OK? Has anything gone wrong?
