ever few minutes a very annoying buzzing noise comes from the computer
if i bang the side of the computer, it stops... but only momentarily
the buzzing noise comes and goes every so often, but it very annoying
i dont think it is the fan, because the fan has a noise of its own, but this is a separate annoying buzzing/hissing noise
theres about 5 minutes of no noise, then 5 minutes of buzzing, and its a cycle that repeats
what should i do?
thanks a lot
