Laptop making funny noises when typing?

I have recently bought a new laptop. It's an Advent Modena M201, however everytime I press any key on the keypad the laptop starts making a weird buzzing sound (it's it quiet but still noticeable). Also when i have headphones in there is a loud noise, kind of like white noise when you tune between two radio stations through the headphones and also the buzzing sound from the keys is amplified through the headphones. Also i have noticed that the buzzing happens for as long as my finger is on the touch pad as well. Has anyone else experience these problems with an advent (or any other) laptop? Do you think i should take it to a computer shop to get it checked out, or does anyone know of a website with a email service (or something similar) who I would be able to contact and who would be able to tell me what the problem is? Cheers.
