I've had this computer for almost more than a year now, it never had any problem until today. When i try to turn the pc on it turns on for an instant and turns off right after. I don't have much computer experience so i have no idea what to do. Yesterday when i turned it off and removed the power i pressed the power ON button again by accident and it removed all power orsomething from my computer ( idk it just looked like all electricity was drained then it turned off)
