As asked, the first thing to note is any signs of life (fans, front-panel LEDs, drive activity, keyboard lights or beep codes). As said, answering those basic observations makes it far easier to pin the fault.

  • Check basic POST signs first: fans spinning, motherboard LEDs, keyboard NumLock/CapsLock toggling, and any beep pattern. If literally nothing happens, suspect power or a short.
  • Try a minimal bench boot: power the board outside the case on a nonconductive surface with only CPU, one known-good memory stick, and video output. Remove all drives and add-in cards.
  • Reseat everything: memory, video card (if present), and both main power connectors (24-pin and CPU 4/8-pin). Inspect the CPU socket area for bent pins and confirm the cooler is seated.
  • Verify the display chain: test the monitor and cable on another PC and try alternate connectors/inputs. “Blank” screen vs “No signal” are different clues.
  • Listen for POST/beep codes: if there’s no onboard speaker, add one. Note the pattern and consult the motherboard manual for meaning.
  • Reset CMOS: clear the CMOS with the jumper or remove the battery for 30+ seconds to rule out a corrupted setting.
  • Check the PSU: swap with a known-good supply or have voltages measured. Avoid guessing with the paperclip test unless comfortable with mains wiring.
  • If power and POST still fail, swap memory sticks, try a different video output path, and consider BIOS/CPU compatibility as a cause (some CPUs require an updated BIOS to POST).

Report back the exact symptoms: which fans spin, any LEDs on the board, the beep pattern (if any), whether the monitor reports “no signal” or is simply black, and what changed when you reseated parts. These details will focus the next diagnostic steps.
