I built a new PC about 20 days ago. Until 9 PM yesterday, it was working properly. I normally powered it off. When I tried to restart at 11 AM, it didn’t turn on—no lights, no fans, nothing. The next day at around 9 AM it worked again, so I used it for a short time. After that, I restarted it several times, but it never came back. Today at about 9 AM it started fine again. All updates were applied recently and everything seems normal. Temperatures stayed below 40°C. It appears to power up every 12 to 24 hours. What might be wrong and why? Please help me understand the situation.

The power source could be faulty, so it needs to discharge a capacitor before the soft switch functions properly. Probably a guess—consider using another power supply.
