Just got my Msi GTX 760 and installed it into PCI-E slot #2 and started computer, windows loads and asks for my password, I continue and proceed to "windows is loading" screen; then after windows is finished loading the screen turns black. I can press ctrl+alt+del and that shows up, but that is all. Please help. I have a msi z87-45g motherboard and a 650 watt PSU.
