My PC boots normally whilst using the integrated gpu however when I try using my gtx 670 it does not display a signal at all! I've tried different connectors hdmi, vga and dvi and it hasn't worked, I've even bought a new power supply and motherboard to see if that would resolve the issue but to no avail I've connected everything correctly and I've even tried one ram in each slot etc.
My specs are
MSI Z68A-GD55 b3
Msi gtx 670
I5 2320 3ghz
xfx pro 750w
