my friend recenlty built me a new PC, everything was going well but after a week i heard a very loud noise coming from the tower. this only happens when I turn the computer on, it lasts for about 15 seconds then stops, but im sure this time is now getting longer.
the fan is making all this noise, and its a Blue one thats attatched to the motherboard. i havent got the spec on me at the moment (i'm in work) but its a brand new one, compatible with my 3.0 Ghz pentium proccessor.
any ideas why its started making the noise nad how i can stop it!
