My build:
Graphics Card: XFX Radeon 7970DD
CPU: Intel i7 3770k
PSU: HX850 corsair
RAM: Corsair Vengence 8x2GB 1600MHz
Sound Card: Auzentech HomeTheatre HD
Motherboard: MSI Z77 MPower

My computer can perform regular tasks without crashing. But when I put stress on it, such as playing Assassins Creed Black Flag or sometimes League of Legends my computer crashes (Just restarts with no error message). I've been monitoring temps with MSI Afterburner and the GPU and CPU temps are normal. My GPU maxed out at 75C. I made sure all connections were sturdy, I fully cleaned out dust from my computer, and I ran a GPU stress test with FurMark and as soon as I clicked OK to start the stress test my Comp crashed.

I'm not sure what's wrong here but I would like someone who maybe had a similar issue or is experience with this kind of thing to let me know. Thanks :)

I'd venture to guess the PSU, when a GPU has issues, it generally will crash the video drivers and you'll lose picture or never even get picture (though it can definetly reboot the PC as well depending on the cause) but a random reboot sounds more like your PSU can't handle the load the GPU is putting on it and it's triggering a reset to protect itself from being pushed too far. that being said, the HX850 is a massively capable PSU that should have no problem with your setup, so i'm going to say you got a lemon

If you take out the 7970, is the pc still stable? If it is not then you have a power supply issue.
Run a memtest to see of you have a faulty ram sticks.
Reset everything to default. Set both cpu and gpu to stock speeds.
Test your pc without the soundcard in.
