Well it shouldn't buzz. You can always hear the fans whirring, but if they break down, then your system can overheat and basically fry - yes, it has the potential to cause major damage. Get it checked out.
Hi.
Anyone know what may be causing that noise? Only comes on every now and then. And/or know of a computer technician who can come and have a look at it? it's a PC. Thanks very much.
