Radeon HD7970: Screen blacks out, white noise plays through headset


In the last few months, I purchased a new gaming computer. It has the following specs:

Intel Sandy Bridge -E I7-3930K 3.2Ghz 12mb Cache Unlocked CPU LGA2011
Gigabyte X79-UD5 Motherboard
G-Skill Ripjaws Z 16GB DDR3 2133 Black Edition Ram (4 x 4GB)
Corsair Liquid Cooling System
OCZ Vertex 4 128GB SATA3 SSD
Bluray Rom/ DVD/CD Writer
Radeon HD7970 3GB Graphic Card
OCZ 750W Bronze Certified Modular PSU
Coolermaster 692 Advanced Gaming ATX Case.

I purchased this computer so that I was able to play the latest games on the highest settings, while also streaming them. In the end, I was unable to stream, because the Radeon HD7970 GFX card was not compatible with the program Xsplit (info here: http://www.xsplit.com/forum/viewtopic.php?f=2&t=5058) I was pretty annoyed, and did some more research, finding a new thread a short while later, with information referring to unofficial drivers that worked better than the current ones, (thread here: http://www.xsplit.com/forum/viewtopic.php?f=91&t=12055). I installed the Catalyst Control Centre that came with the unofficial beta driver (found here: http://www.rage3d.com/board/showthread.php?t=33992611) and I thought all would be well. I tried streaming and huzzah! It works! I can stream for as long as I want without the program crashing. But alas, with the good also comes something bad. When I enter a game, after a random period of time, the screen goes black with a message 'no signal' appearing seconds later. A few seconds after that, I get a kind of 'white noise' coming through my headset. I'm looking towards the drivers as being the main problem in all of this, however I'm not sure what I should do to fix the problem. It happens randomly in any game I play, and occasionally outside of games, which makes it difficult to use my computer. Hopefully I will be able to get some help! I'm not 100% confident with my computer skills in regards to fixing hardware faults, so I may need step by step guides, if possible, but I'm sure we can get to that later. Thanks so much, in advance, for your help!

  1. Alright, so I have done a few things, mainly running Furmark, which determined that my computer crashes when it gets over 50 degrees and also at 50%ish GPU usage. I also used Driver Sweeper, removing my drivers, and rollbacked my computer prior to when I installed the drivers. After doing this, I ran Furmark again, which still did the exact same thing. White noise no longer comes through my headset, which is a good thing I believe. I have no idea what to do from here, so any help is greatly appreciated.
