Strange awakening problems

[ewantheocelot]

After reawakening my pc, is freezes and looks like there is a problem with the monitor. Switching off and on the monitor just makes it say that there is no input from the displayport. I then press the reset button, login then restart and that fixes it. I thought it was Nvidia drivers as it only started appearing after I updated them (and nvidia control panel was causing a blue screen when trying to enable SLI which I had never switched off) but after reinstalling them the problem is still there.I am using Windows 8.1 Pro. I recently added the microphone but it didn't require any drivers so I don't why it would be that. Also I have tried using the displayport on the second GTX 780 Ti and it wouldn't fix it. Any help would be greatly appreciated. (I have tried in the troubleshooting thread but no one has replied)
