My computer went into a black screen and my keyboard did not light up and my gpu's fans did not spin, nor did the startup noise appear in windows. What I saw was just a black screen. Bios on ram acted strange since I replaced the power supply. Thinking about replacing the entire computer if it is a motherboard issue. Recently sent in for repair. Computer acted strange when I was submitting online homework for college.
