So the problem is quite simple and yet very strange. Every time I turn off my PC, it wont turn on again until I press reset CMOS button on the motherboard. What WILL happen before I decide to press the button is this: 1. I press power button. 2. PSU turns on for half a second. 3. Some click sound happens. 4. PC turns off. The whole process is repeated infinitely. The computer is about 2 years old and this problem hasnt occured before. Also I didnt make any changes prior to this problem. note1: after I press reset cmos button, the pc works perfectly once is boots up... I can (if I want to) make changes to bios even and it will work. It only has problem to turn on from "powered off" position. note2: I will add detailed specs if needed but I really dont think its neccessary. note3: I dont make any changes to bios after I reset it using the button.
