Hi, I have just built my PC but I'm very new to this game. When I turn on the PC Everything seems ok but I get the 'no input signal' from the montior. After turning the power off at the the PSU and turning the PC on again everything works fine. This happens everytime. As the PC works I know this may not be a major issue but is there anyway to getting it to work first time? Help much appreciated. Thanks
