Sounds weird.. but i do not know if its a virus.. as iv never heard of a virus doing that.. and with a noise.. there could a lose connection somewhere? you could ask your parents or something to look at it.. remember to unplug from the mains before looking..
If you think its a virus have you done a virus scan? and perhaps try a spyware scan.. if you don't have a spyware scanner.. you can download Ad-Aware 2007 the free version from here:

make sure you click the free version..
umm i don't know what else to suggest.. if it keeps happening i think its either time for a new computer or you could call an IT technician round or something
