My steps to my problem. Really hoping someone can shed some light, for a possible quick fix. :(

I first removed my old 460 card (still working)
.
I inserted the 660GTX
.
I installed the latest drivers [347.25]
.
Simple tasks work fine. Browsing, watching 1080p rips etc...
.
Launched Call of Duty 4: Modern Warfare Multiplayer: Works fine, until the map loading completes. I chose my weapon and started sprinting and the display goes blank. Not for a few seconds, but forever, until reboot. The fan on the tower still circulates. the keyboard lights are on but unresponsive.
.
The system would make a quick *tsp* or *hiss* sound, as the screen goes black..
.
Rebooted
.
Launched FIFA15, screen goes blank even before a match begins.
.
Hard shutdown
.
Unplugged the DVD drive, just in case it was a power issue with a simple fix.
.
Reinstalled GPU drivers.
.
Ran FurMark. The 720p and 1080p tests ran flawlessly. GPU temps went up to 70-71 Celsius at max. test ran for a few minutes without an issue.
At this point, I was thinking thinking "hey maybe, problem solved".
.
Smile inserted to face " :) "
.
Relaunched Call Of Duty 4: Modern Warfare
.
Display goes permanently blank again, until reboot. [No signal] on TV.
.
