I have a HP Pavilion p6130y Desktop and there isn't a signal getting to the monitor. I have done all my checks and it isnt the monitor or cable. It is somewhere from the port back, Im guessing mobo. It was working fine the night before, but when i booted up the next day nothing. It seems to start booting, but i dont think that it is booting all the way. The mouse and keyboard arent lighting up either. Has anyone had this problem before or have any input? Am i on the right path with mobo diagnosis?
