Hello, I guess I will start off with my system specs before I get into the problem itself.

AMD FX-9370 processor (corsair H100i water cooling)
16GB (4x4GB) of DDR3 corsair RAM running at 1333MHz.
Gigabyte 970A-DS3P motherboard
MSI HD Radeon 7970
I honestly forget the PSU brand, but it wasn't one of the odd off brands. I know its a 650watt Gold certified with enough voltage to run my card twice.
250GB PNY SSD (primary), 500GB WD and 2TB WD storage HDDs, both 7200rpm
Coolermaster HAF 932 case with the top fans replaced with the H100i for the CPU, 120mm fan in the back, 240mm in front and side.
Currently, windows 8 Pro 64-bit. Windows 7 Home Premium 64-bit at one point.

So the build has been working fine for about a year since the last upgrade, which is when I swapped the mobo and cpu as well as got the water cooling. The system before that had no issues either, I simply decided it was time to upgrade. The computer is kept in a wide, mostly empty well ventilated living room. It is out in the open and not boxed in or covered. No pets and I keep it clean.

The issues began about a month ago and has not lessened or worsened much over that time. Randomly while idling at the desktop after being turned on, idling after being on all day, watching a video, typing this message, playing a game - you get the idea, I cannot find any sort of pattern. The system seems to "lock-up" somewhat. In chrome for example, I can see the page I am on. I can highlight text and move the mouse and type if I have a text box selected. When the freeze up happens though, clicking a text box or right clicking anything or trying command keys does nothing. No messages about stuff not responding, as if the screen has frozen up. Sound also stops, however not entirely. When playing Saints Row 3 for example, it will happen quite often. I can continue driving and shooting but any npc talking will stop, bystanders will walk into walls and cars will crash. If I keep driving I will soon hit the end of the loaded world. All sounds of engines, car tires, yelling, explosions - all gone. Gunshots and my character saying things in pain remain, however. If I try to pause the game, the pause menu will not come up but the game will lock up and I will have to wait until the issue is gone again. The usual time is between 30 seconds and a minute and a half.

Now at this point it sounds like a video card driver or video card issue. However if I play Arma 3 or TERA for example the issue does not happen. At all. If I tab out and go search something on google however it can happen as usual. There are several different errors in event viewer but none of them match in time with the freezes and the freezes are much more numerous than the number of errors and as far as I can tell none of them have to do with it. I will however post them anyway in case someone has an idea.

I stress tested everything as well.

Video card: Stress tested for 30 minutes on Valley Benchmark 1.0 maximum settings, 1920x1080. FPS was between 5-20 depending on the scenes but no freezing and the sound played fine the whole time. Temperatures eventually topped off at 71C which although high is still within safe range.

CPU: Left on Prime95 blend test and the high heat option for an hour each. All cores ran fine, none failed or stopped or slowed. Temperatures never exceeded 57C thanks to the H100i. I also tested the CPU with QA+Win and it passed fine.

SSD: Tested for failure with QA+Win diagnostics and Western Digital Data Lifeguard Diagnostics. Passed all of the tests fine.

Motherboard: As far as I can tell / know there are not specific tests for motherboards apart from telling if they work at all really. The temperatures during testing of the other components however never exceeded 48C.

RAM: QA+Win diagnostics ran twice, memtest went fine as well.

With all of the hardware diagnostics turning out fine, I tried a fresh install of the operating system after formatting the drive. I put windows 7 back on again with no luck. Then put windows 8 on and the issue seemed fixed for about 2 days, the longest I had gone without an incident. There was no change in my habits during that time however besides that I began playing TERA, so I suspect that is another game not affected by the freeze. When I tab out to check things it still freezes sometimes but I spent most of my time doing early game stuff so I didnt need to tab out much.

I tried pulling out the RAM and putting it back in stick by stick, no luck. With each OS install came different drivers, since win 7 and 8 have different ones of course. I also tried both the stable and beta versions of the drivers for each, straight from the manufacturer where I have gotten them for years.

Here are the errors I currently am getting sometimes in event viewer on windows 8:

"The system firmware has changed the processor's memory type range registers (MTRRs) across a sleep state transition (S5). This can result in reduced resume performance." In the four days that windows 8 has been installed, this one always happens twice a day, no more or less. There is no relation in the times though as far as I can tell.

"The Service KMSELDI service terminated unexpectedly. It has done this 1 time(s)." Despite what the message says this has happened twice.

"The IP Helper service terminated with the following error:
The service cannot be started, either because it is disabled or because it has no enabled devices associated with it."

"A timeout was reached (30000 milliseconds) while waiting for the Windows Error Reporting Service service to connect."

"Crash dump initialization failed!"

"The server Microsoft.WindowsLive.Platform.Service.RemoteProcess did not register with DCOM within the required timeout."

"The Network List Service service terminated with the following error:
The device is not ready."

I honestly can't think of anything else to do. Today I will swap the video card out and see how that goes when I get home from work later. I don't have another board or CPU to swap out, or a PSU. Ill take any ideas though, and I will try my best to try them. I known some people I can borrow parts to test with from but I would prefer not to if I can. Thanks for reading and hopefully helping out.

Be sure to not just get any PSU, or just any PSU that says it's got this or that certification. 80plus certification is worthless. Lot's of them are fake in fact. Even when the rating is accurate, it means little about the quality or reliability, much less the ability to consistently maintain it's rated sustained capacity. Many units advertised ratings are peak rather than continuous and looking at the specifications label often indicates a MUCH lower sustained capacity and amperages well below what you would have on a similarly rated but high quality unit.

Your HD 7970 calls for a 550w unit but if you have any overclocked hardware I'd increase that to at least 620w. I'd highly recommend finding a unit of Tier 2B or higher ranking...
Clearly you're no novice, but I have to say, in all honesty, every time, and I mean ALMOST every time, I hear this:

Or something similar, it's usually the PSU. I'd try another one if possible. Even if yours was sufficient at some point, it's still possible there has been a failure. I've seen Platinum EVGA and Seasonic units take a shit for no apparent reason. Electronics just fail sometimes. Since your issues are widely varied, about the only component that affects EVERYTHING and can present as a failure common to EVERY other component, that's where I'd begin looking.

I am going to purchase a new power supply on my way to work tonight and see if that fixes it. If it does, cool, cheapest part to replace. If it doesn't, I will return the PSU and start setting aside a bit of money for a new motherboard I guess.
