First off, I apologize for the wall of text but I have had this problem for quite some time without a solution and I am trying to be as descriptive as possible.

I built my computer a year and a half ago. I have a 500w PSU, GIGABYTE 7770C, AMD FX-8120, 2x4GB Corsair Vengeance, a 3TB WD Green, and a 240GB SanDisk SSD.

When I initially built my computer, I used an old IDE drive until the following Christmas in which I got my current storage system. I use the SSD for my OS and a few applications, and the 3TB for my games and other media.

About a year ago, I had been gaming from dawn until the next dawn when my computer screen went black, and the game audio did some rather interesting things. The current sound file playing finished and began to loop. This ranged from a 3 minute music file to a half-second gunshot noise. The monitor lost signal and proceeded to turn off, while Skype continued to work completely fine. Keyboard inputs do not make a difference while the monitor is off. The only way to end it was to turn my computer off. I booted the computer again, and launched back into the game followed by an instantaneous crash after rendering a single 3D frame. I assumed it was overheating, so I let it cool for several hours.

This issue has been occurring in random intervals since, not being affected by overclocking, reseating of GPU/RAM, or temperature of the CPU/GPU/HDD/RAM. It either happens at the launch of a game, after 20 seconds, or after several hours. Recently, it has been doing it more and more often, to the point where I have not successfully played any full screen game in the past week. Notably, it has crashed playing Starbound and Terraria, so I do not believe it is limited to 3D games. Anything moderately demanding of my GPU seems to cut the signal. This has been of the utmost annoyance for the past 10 months, and I cannot seem to find or figure out a solution. I have updated drivers multiple times.

Any and all help is greatly appreciated. I will be happy to provide more details.
 
Because you have the combination Fx 8 series cpu with the MB that only has 4+1 power phase, so that it will be little bit trick. Here is the link https://spreadsheets.google.com/spreadsheet/pub?key=0AgN1D79Joo7tdE9xMUFlMEVWeFhuckJEVF9aMmtpUFE&gid=2 you can see that "User-experience: Will throttle on overclocked FX 8-core" because the power phase count is lower, sometime you will have that problem, like the PC is freeze or BSOD because the MB is over head that caused by the lower power phase (VRM).
Try unclock the cpu frequency if you can. or install a CPU cooler with a top-down blowing design so that is can cool the MB components that surround the CPU.
Let me know that will work or not.

I overclocked the CPU a very long time ago with no problems. My fan is more than adequate (almost doesn't fit in the case) to supply sufficient cooling to the CPU, and it only reaches around 50 Celsius when gaming. It also cools top down, and the airflow reaches most of the motherboard as far as I'm concerned. I restored default BIOS settings, even though my CPU was on the default clock, and the problem has not been changed. Also, I do know that my mother board is the ASRock 970DE3.

I greatly appreciate your concern and willingness to help, but my problem persists.
