Continuous high noise on start up

[High1]

Hello
When I switch on my Packard Bell PC it has started to make a continuous high pitched noise and no screen or keyboard lights appear. Nothing appears on the screen
 It was OK earlier today when I shut it down
 What could be wrong, please?

It's most likely the fan on the CPU...replace it.
You can remove the side panel to confirm this...

Hi

Most likely the power supply is screaming due to an overload or it can't support the load of the computer. If you are not comfortable working on computers it would be best to have a technician check it for you. In the mean time leave it tuned off at the wall.
If you are comfortable replacing computer parts, plug the computer in and see if you can isolate where the noise is coming from. If it is the power supply please post the model of Packard Bell or some pictures of the current power supply and motherboard so a suitable replacement can be found.

Thank you for your replies.

I changed the position of my screen on the computer desk and the noise disappeared. All seems to be working well at the moment - fingers crossed.

Thanks again
