[Solved] PC starts but no signal to monitor

I hope this post can help someone having the same issue as I faced.

Symptoms

• Motherboard green light on when power cable plugged in
• On start up:
  – No signal to monitor
  – Can’t enter BIOS POST check
  – Fans are spinning as normal (including CPU cooler fan)

Fix Solution

Check your power supply. In my case a replacement of power supply fixed the issue.
