Windows 10: Black screen and high pitched buzzing noise on start up.

I have an Acer Aspire Z series desktop on Windows 7 Home Premium, it's about 12 or 13 years old, I have E Set anti virus. In the last few months it occasionally shows a black screen and high pitched buzzing noise on start up so I switch it off and restart later and it's ok. But now it is permanently on black screen and buzzing noise. I've read some proposed solutions but can't get past the black screen. Has it just slowly died due to its age and would a technician be able to save any files on the hard drive before I ditch it?

High Pitched Screching Noise

My pc is making a high pitched screeching noise and I can't make it stop without muting the volume. It doesn't start until I increase the volume to 100%. In the meantime, I can hear my hitting keystrokes or tapping on the pc echoing back through the speakers.
How do I make it stop doing this? I'm not sure what I did to make it start doing it. It also make a high pitched noise when I close the lid until it shuts off.
