For Online Computer Support, Ask a Computer Technician
Hello my name is***** am sorry you have encountered this kind of problem. Just to verify is the machine not turning on at all or powering up?
Ok when you push the power button any response at all and on the back of the machine do you see an led light at all anywhere?
Also check the power supply, usually there is a light on the black power cord brick assuming I'm looking at the right model.
Sounds like there is either a problem with the power supply or a motherboard malfunction causing this problem I am sad to say. Does the noise sound like it's inside the machine?
Do the fans on the back of the machine look like they are running at all when you push the power button?
Sorry for the late response we had power outage here. If the fans are running or shutting off or not running at all I would first try and have the power supply changed if that fails then you may want to have the motherboard serviced.
If you have any further questions for me please let me know. If not don't forget to leave positive feedback for my time and information using the rating option thank you.
