My mobo MSI Z87 G45 doesn't detect my GPU GTX 670

Hi guys,

I've just build my new computer with,

MSI Z87 G45 mobo
Intel i7 4770K
G skill 2x 8GB 1866
Gigabyte GTX 670 4GB GPU

I am struggling get a signal from my GPU.
Once I turn the computer on I doesn't get any signals to my monitor.

But when I use on board graphics it works perfectly.

Tried GTX 670 on another computer and it works perfectly on that one.

Any help would be really appreciated.

What make/model/wattage power supply are you using?

I think this card requires a PSU with at least 550 watts of constant (not peak) output. If you're up to it, try swapping the power supplies between the PCs and see what happens.

 

Take a look at your BIOS as well, you may need to set the card as preferred video.
