Hi guys..I received my system yesterday and i'm over the moon with it apart from a couple of little problems, 1st ..when I come back to the pc after manually putting it in sleep mode I click the mouse button and the pc fires up but the monitor stays in sleep mode and nothing I do wakes it up not even the 'reset' button works so I have to hold my finger on the power button to turn it off. 2nd there seems to be a lot of fan noise and im wondering if the bios is set so that the cpu fan runs quiet or is this not possible with it being overclocked. 3rd Will i void the warranty if I install the tv tuner out of my old pc into my new scan pc and finally when it is turned off but still switched on at the wall there is a very high pitched screech.squeel sound coming from inside although it is very quiet, I noticed it when I came down to it this morning...it carried on after I had started the pc then disappeared after a minuit or so. Sorry for the long winded post, I thought it best to sort out all the teething problems at once
