I have had some problems with my PC (I think more specifically my graphics card over heating). I am not certain this is the problem, but my monitor will randomly go off. What I have done is whipped the side of my PC off and put a full size home fan (http://www.argos.co.uk/static/Product/partNumber/4251824.htm like that) next to my PC - blowing inside. Is this likely to be too much wind for the PC components or will it be OK? It has brought the temp down a good 5 degrees or so.
