For — a blank monitor after a normal shutdown is usually one of four things: monitor/cable/input, graphics card, system board/CPU/RAM, or power delivery. The following checks go from least-invasive to more involved so the faulty part can be isolated without guessing.

  • Confirm whether the PC actually powers on: front-panel LED, case fans, drive activity, and any internal speaker beeps. If nothing powers up, check mains, the monitor power, the PSU switch and the mains lead.
  • Check the monitor itself: power LED, correct input (HDMI/DP/DVI/VGA), and try the monitor on a known-good device (or try a known-good monitor/TV on the PC). Swap the video cable and try a different port.
  • If the PC shows power but still no picture: reseat the graphics card and make sure any PCIe power cables are plugged. If the motherboard has video outputs and the CPU has integrated graphics, remove the discrete GPU and test using the motherboard port.
  • Test RAM quickly: with power off and unplugged, remove all memory sticks and try booting with a single stick in the primary slot; test each stick one at a time.
  • Note any POST beeps or motherboard status LEDs and consult the board manual for their meaning — beep patterns vary by BIOS.

Safety and next steps: always unplug and ground yourself before touching components. Clearing CMOS (remove battery briefly or use the clear-jumper) can help if BIOS settings got corrupted. If none of these restore a picture, common failing parts are the GPU, PSU, or motherboard/CPU. Diagnosis is fastest with a known-good spare GPU or PSU; otherwise a local repair shop can run those component swaps safely.
