Yeah, all the fans are spinning and everything is running but the monitor is detecting that a VGA or HDMI cable is being plugged in but not outputting any image.

Thankyou for correcting me on the HD part, that was the iPad's fault, I was round my friends house trying to work out why it wasn't working but now i'm home I can write a better reason.

He is upgrading his computer from a stock Vi Box that he bought on eBay numerous years ago and he was sick of being unable to play high end games so I told him what he needed and to go any buy it, so he did and over the next couple of weeks the parts started to arrive. Once everything had arrived I built the computer for him as I have computer building knowledge after building my fair share of them, but this is the first time I have encountered a problem such as this. All the fans in the case are spinning, the board is receiving power from the 4Pin ATX because the Heat Sink fan is spinning, So I know its not a board issue also it was brand new, even the fans on the GPU are spinning because yes, the 6pin cable is plugged in but it's not giving an output off, is this a compatablitiy issue? SPECS: | MOBO = Gigabyte 970A-SD3 | GPU - MSI HD 7850 | GPU - PSU | Ambiance 80+ 700w | I usually work with Intel but I don't think that with it being AMD it would make a difference?
