I just bought a new setup:
Intel i7 3770K
MSI GTX 660 TFZ
8GB corsair vengeance
I've connected them all correctly... there mobo has a panel for debugging, and it says: "97" which means:"Console Output devices connect (ex. Monitor is lighted)"
i tried to remove the GFX card and to use the onboard. It worked. I tried to install windows, but the keyboard and the mouse is not working on the installation process...
Not sure what's going on wrong here...the gfx card should work just fine.
