Is it like a siren? then it may be that your CPU is overheating. Check your heatsink and Fan.

Have you tried to let it cool down and try booting again? Does it then still do that? and is the sound heard immediately or after a delay?

If it is a series of BEEPs then you need to understand the beeps and then look up the beep code for your BIOS here:

You have not said what the beep code is. You have not told us anything about your system specs, or about the BIOS on your PC.
The answers you get or dont get depends on the quality of your question and information that you provide.

Try telling your doctor I am unwell without telling him your symptoms. He won't know what is wrong. Same here. So give us more to go on.

For a start have you checked your beep code against the links I posted?

That alone does not help.

Which BIOS?
What make is your motherboard?
Is the graphics separate or on board?
If separate which graphics card?

In short what is your system specification?

Have you checked your beep code against the links I posted in post #1?
You should be able to do so yourself now you know your beep code and only you now your BIOS as you have not given us this information. This is what we would do. So why not do it yourself?

How do you expect help when you do not provide adequate information?
