Computer starts up yet screen remains dark, fans operate and illuminate, no USB connection detected
Hi, your PC was functioning properly before, but after shutting it down and restarting, it stopped booting and showing nothing. When you power it back on, the fans spin and RAM lights up, yet there’s no display output. The RGB keyboard and mouse also don’t activate.
You’ve already tried several fixes with a friend: re-seating CPU and RAM, using another A320M-S2H board, switching to an A320M-S2H with integrated graphics, testing RAM in different slots, checking SSD connectivity, inspecting GPU placement and power cables. Even when using the CPU with integrated graphics on another board, no display appears. The Ethernet port still lights up when powered.
Your system specs are: Ryzen 5 2600 Gigabyte A320M-S2H (two tested), RX 570 16GB RAM, 500W cooler, CoolerMaster (model not specified), Windows 11. You don’t have another PSU available right now, but you suspect a failing power supply might be the cause even though fans and LEDs work.
Could a weak or failing PSU be responsible? This could explain why components power on but nothing appears on screen. If you can, check the PSU’s voltage output and look for any error codes—those might give more clues.
You confirmed the steps were followed correctly. The system ended with a standard shutdown, as expected after modifications.
