Chosen Solution

I removed my processor and cleaned motherboard and installed it (Processor)but now

  1. cpu fan is running
  2. Mouse light is coming But the 1.display does not come
  3. The keyboard light does not come on and does not start my computer

The first step to fixing No Display on Boot is to restart your PC properly. Hold the power button for at least 5 seconds to turn your PC off, then turn it back on. If your PC was set to sleep or hibernate before the problem started, this could solve the issue right away. Regards, Will
