ASUS GTX 970 Locking at Max Clockrate (Boost Clock)

[NothingsReal]

So I have no idea on what's going on with this card or how to fix it. This happens whether I'm sitting on the desktop for 20 minutes, browsing Facebook or gaming. About 20-30 minutes into my system being logged into Windows 10, my GTX 970 will lock itself at the max boost clock (1508mhz in my case) and will not clock down until I either log out of my user account and log back in or restart my PC. This has happened before when the card was at stock speeds. I've used DDU to boot into safe mode and uninstall the drivers and then restart and reinstall them, no luck. I've tried installing nothing but the graphics driver itself, no NVIDIA software, no audio drivers, nothing. No luck there either. I'm really hoping someone can help me out. Here's the full PC specs.
