Since reports the system powers (fans spin) but there’s no POST beep and no video, the likely causes are: front-panel/BIOS/speaker, video output (GPU/monitor/cable), RAM seating, missing CPU power, motherboard short/fault, or a PSU that can spin fans but fails under load. ’s point about connectors and /’s suggestions about PSU or motherboard are all valid — the next step is a short, ordered isolation routine to avoid replacing parts blindly.

Recommended troubleshooting (follow in order):

  1. Confirm monitor and cable: power LED on monitor, correct input selected, try another cable or monitor.
  2. Check POST speaker: many boards don’t include one. Install a small chassis speaker or use motherboard debug LEDs if present. No speaker can hide POST codes.
  3. Minimal boot outside case: motherboard + CPU + one RAM stick + PSU + monitor (use onboard video if available; otherwise GPU). All other drives/peripherals disconnected.
  4. Reseat/try RAM: use a single stick in the recommended DIMM slot and try each module one at a time.
  5. Verify power connectors: 24-pin ATX fully seated and the 4/8-pin CPU power connector present and latched. Also ensure any GPU 6/8-pin connectors are plugged if the card requires them.
  6. Clear CMOS: power off, unplug, remove the CMOS battery for 5–10 minutes or use the clear jumper per the manual.
  7. Inspect for shorts/damage: check standoffs, no extra metal between board and case, look for bulging caps or debris in the CPU socket. Breadboard the board on cardboard if a short is suspected.
  8. PSU check last: swap with a known-good PSU or have the PSU tested. Avoid improvised tests unless experienced — PSUs can be dangerous.

If minimal boot still produces no video and no beep with a confirmed speaker, likelihood rises that the motherboard or CPU is faulty. Document the steps tried before pursuing an RMA so the vendor won’t reject the claim as “untested.”

Just listing the components isn't helpful. When you turn it on, does ANYTHING work, such as fans and such? Have you verified that you plugged the power supply into the correct headers/plugs? If it doesn't even turn on the power supply fan, have you checked if the power supply circuit breaker / fuse hasn't tripped / blown?

I have built a lot of systems from components, but many people have problems doing so because they don't utilize due dilligence in making sure that all the i's are dotted and t's are crossed properly.

I have plugged all of the cables in. The fans start working but no display shows up and the speaker dosent beep at all.

It's the problem in Motherboard. Does the indicator (power/hdd) blink? if it does, the motherboard needs to check or replace

Try changing the power supply. The right amount of power isnt going in to power the computer up.
