Crashing with buzzing noise?

I am playing some games and about 20-30 minutes in to the game my middle monitor turns black, I get a loud buzzing noise from my headphones, than all 3 of my monitors say "No Signal" and I have to turn off my PC.

Specs:

Intel 2500k @ 3.6GHz
NVidia GTX 580 3GB SLI (x2)
Gigabyte P67A-UD7-B3
Corsair 16GB RAM
CoolerMaster H212+
Corsair HX1050w
Windows 7 Ultimate 64 Bit
Intel 320 120GB SSD
WD 1TB Cavier Black

Was going to add the info and the attachment button don't do anything. :/

EDIT: Using the diagnostic tool in the eventapp.txt I found this:
