Windows 7: Whys my computer beep when i turn it on?

It's a new computer when i turned it on before it didn't beep but no it seems every time i turn it on it beeps. It beeped only when i restarted before. Not saying system doesnt boot up it does but just asking is there anyway to stop the beeping and can you tell me why it beeps?

Thanks

Weclome,
A change in sounds indicates that there has been a change in the computer, many times a problem. How many beeps?

I have found this information on the beep codes

Computer Post / Beep codes

One beep then it boots up.

Read the information that I have provided, one beep seems to be OK.

Yeah i guess it's ok but why does it beep now and not when i turned it on for the first 2 times?

Don't know why, but ome beep means "everything ok, booting up"

YOu may have missed it, or the computer had to adjust. It seems that no beep means no power and that was not the situation. I suggest that you forget about it and enjoy the great new OS and the new computer. It feels great to have a new one.

If you have an internal speaker hooked up it will beep when you`ve past the POST.

Eh ok I'll just leave it alone so i don't mes up everything else after reading the article if it didn't beep and there was something wrong then i couldn't tell how many beeps, if i tried turning it off or something. So one beeps ok.

Thanks
