Hi phantom9056,
Please let me know the status of the power light on the system tower. Do you hear any beeps when you turn on the system? I will recommnd you to drain the flea power and see if that makes a difference:
- Disconnect all the external peripherals.
- Unplug all the cables connected to the system including the monitor's cable and the power cable.
- Press and hold the power button for 10 to 15 seconds.
- Connect the power cable and the monitor back and check if the system is working fine.
Keep me posted. Please reply for any further questions.
