Any of the pc techies on here like to run me through how I'd go about doing this?
Im am an absolute n00b when it comes to computer components.

1st off, is there anyway of silencing my computer within the processing itself (.i.e. removing unnecessary background apps and things?)

and 2nd, I'm looking at spending no higher than £80 on whatever it needs,

I know this is an extremely vague description so im not expecting a load of replies but if any of you guys know how to help with this (or think you do) then please chip in :)

It sounds as though its coming from either the Harddrive or the fans, its definitely not coming from my interface/monitors/computer monitor or anything else electrical nearby
