I have a problem with my desktop. It was working fine yesterday and we put the computer into sleep mode. A couple of hours later we moved the mouse / pressed a key on the keyboard and nothing happened. Had to resort to holding the power button down on the tower unit, this turned the pc off. Left it a few minutes and re-started it. The unit powers up but nothing comes up on the screen, also the usb ports arent working (tried charging phone and doesnt do it) - the pc is only a couple of months old. Any suggestins i can try myself before i take it back to the shop under warrenty?
Thanks in advance
