When pressing the power button, my computer starts making start-up noises, but after a few seconds it shuts down. Then, after 2-3 seconds, it automatically starts turning on again and a few seconds later it shuts down again. In other words, it is stuck in an infinite loop of turn on , turn off, turn on, turn off and the only way to escape the loop is by a long press on the power button (which turns it off). The turn-on phase of the loop is so short that you never see anything on the screen during the phase. But you can definitely hear the fan and see light from the bulbs on the case. The turn-on phase isn't followed by any BIOS bip. What could it be?
