Sorry havent been on in a while have been busy. Fn + f9 does nothing I'm afraid. A USB mouse works fine and the performance option for high is not available to me.
I'm near positive it could be a hard drive problem but before forking out for one and having to pass on the costs to the owner I just have to be sure. The noise is repeating like this : click clk,clk,clk,clk,clk,clk....click. This goes on and on for ages aswell..
Thanks in advance.
