After turning my computer on today i noticed a weird sound coming from the back of my monitor. Its a little hard to explain but it kinda of sounds like my computer is passing gas

, it is just a quick sound and only happens every few minutes. Is my monitor dieing? I have left it unplugged for a few hours now and just recently turned it back on and so far it has not made any sounds? Ive tried some other forums asking for help but all i got was someone trying to sell me my dream home in India.
My monitor is a Samsung SyncMaster 226BW(Digital) 22".
If ya need any more info lemme' know.
