Random Shutdowns Most confusing case I have ever dealt with.

So I recently built a computer in February my specs for the purpose of this post are
CPU: AMD FX8320 Black edition
Mobo: Gigabyte 990FXA-UD3
OS:windows 7 64bit
PSU: Thermaltake TR2 600w
GPU: Radeon HD6670 2gb
Heatsink: Cool master Hyper n520

It was all running fine and dandy I was gaming on it and everything. About 3 weeks ago it started to just random shut off(not the standard "windows is shutting down") but i mean literally seemed like the light went out and it shut off. It would only shut off when I opened or launched more than one program. Everyone I talked to including thermaltake told me "its the PSU." So I did an RMA, got it a week and a half later. Installed it annnnnnnnnnnnnnnnnnd It shut off again! Only this time I started hearing a sound before it shuts off, the best way to describe this sound like listen to rice crispis the snap, crackle, and pop. I decided to boot into safe mode, when it came back up and it stayed on. I told my buddy about this and he said it might be a software issue. So we did a clean install of windows 7 and after much updating and blah blah blah. BAM its shuts off again. So I resat my RAM and my GPU still did it, I even tried using a second PSU just in case I have the worst fucking luck ever, and still shut down. Then I check all my cable everythis is fine. My mobo capacitors are still clean and shiny. I told my friend that its still happening and he told me to try a different GPU, so I did and still happened. Only in normal mode, whenever I open a programs almost any program do I hear the snap crackle pop before it shuts down which makes me believe its still the psu. I booted up in safe mode again and decided to push the computer in safe mode. Meaning I opened up steam to update it, origin(started downloading dead space because its currently free), opened 10 chrome tabs, and ran a PSU stress test with OCCT at the same time. To my surprise the damn thing stayed on and everything worked flawlessly not to mention there is no snap, crackle, pop. Im currently writing this post in safe mode.

I forgot to mention my heating doesn't seem to be an issue, I have 3 fans as well. My usual cpu temps range between 25-40c. Also my buddy used an external psu testing device and it said it was fine.

I have never felt this lost or frustrated while trying to fix a computer before. Idk what to do, and I don't really have the money to take it for a $150 diagnostic.

So, after you re installed Windows, did you JUST update Windows or did you also download and/or re install all your games and things? This would include driver and other software related to your hardware.Given that you seem to be operating fine in Safe Mode, my guess would be software as well, specifically drivers.

What I would do personally would be to reinstall Windows 7 and all available updates (or at least the ones I want) and test it as best as possible. No games, no anti-virus software (stay offline though). Not even drivers for my GPU. Just windows. Open a billion things and see if it goes down. Try swapping the PSU before moving onto the next steps. If possible, you could also try swapping the RAM.

Next, install drivers for any hardware you added, one at a time, testing between each. If you've downloaded new drivers recently, especially beta ones, consider sticking with what you've known to work the longest for the time being.

Next start installing your personal software, fastest stuff first (like Chrome), testing between each install. When you install your first game, play it for a while and see how that goes.

Now, assuming you've installed new drivers for your hardware, like the GPU, install those new drivers and see how that goes.

You'll want to keep going like this until you've either installed everything or you've begun crashing. If you get a crash, remove whatever it is you installed and try again. In this way, you'll most likely find your culprit. This will feel monotonous but its likely more time efficient than just trying random fixes.

Hi, you can't pinpoint where the noise is actually coming from? The snap, crackle, pop sounds heat related or something shorting out. It sounds like you've done every trouble shooting countermeasure there is. The only thing left is your motherboard.
