Hi all I just received my pc today but as I put the cables together I found my first problem. Neither of my mouse or keyboard are wireless and there only appears to be one socket which is half blue half green with the symbols (keyboard)/(mouse). He can I use both? My problem number 2 is that the pc turns on properly but despite being connected to my Samsung E1920 monitor via a blue signal cable the monitor power button keeps on flashing and the screen remains blank. I just can not think what it could be other than my cable needs replacing. Thanks for any help
