Is your monitor connected to the mobo or Gpu?
GPU.
Is the power connector in the gpu ok.
Connect it to the mobo. You will need to update the Bios. There seems to be a problem with the Gpu on some of these boards. But the update should fix it.
If you're getting frustrated, maybe take an hour away.
When you get back, make sure everything is seated correctly in the mobo by giving it a firm push (but no more). Forget about the USB and speaker connections for now, as you don't need them to boot the system.
Have you put the ram in?
Are you using DVI-VGA or HDMI to connect the monitor. And the monitor is turned on,yes.
DVI-VGA, I think. is it possible to just have VGA?
BTW, the atx mobo I fitted is pretty close to the edges, is this normal? I have a regular tower case, maybe it's just because I'm used to all the room mATX mobos leave?
