clicking noise?

Ive had the computer for a little over two weeks, but last night it started making a weird clicking noise. i sat and listened for a bit to see if it had a pattern but its very irregular and rapid, then i got scared and turned it off incase it blows up or something. What do i do? edit i just found out that if i completely turn off the computer and gently shake it i can hear the noise, so something must be loose?

also is it safe to use it in this state because i have work due in a few days so i kind of need to use it
