Frequent Black Screens Before and After Clean Install

I've been struggling with my computer display for over a week now. At random times the display will shut off entirely, the sound will loop for a bit, but the LED's on both my mouse and keyboard stay on. I thought that this was a corrupted driver problem so I reformatted my SSD that had Windows 7 on it and upgraded to Windows 10 with a clean install. nvlddmkm.sys was pointed to in the crash dumps on my Windows 7 installation. The clean install did not fix the problem, however, and my display still crashes every 1-2 minutes, rendering my computer near unusable. Luckily, safe mode seems to be keeping my display alive long enough to create this thread.

My system specs are:
CPU: AMD FX(tm)-8350 Eight-Core Processor
MoBo: ASUSTeK COMPUTER INC. SABERTOOTH 990FX R2.0
BIOS: BIOS Date: 01/06/14 14:17:13 Ver: 04.06.05
Drives: (1) ST1000DM003-1CH162 (2) Samsung SSD 850 EVO 250GB (this is my SSD that I wiped)
GPU: NVIDIA GeForce GTX 760
OS: Microsoft Windows 10 Home 64-bit 10586 Multiprocessor Free

I've been carefully monitoring my gpu temperature, as I've heard that that can be a cause of these crashes, but my temp peaks at around 70C, so I doubt that's it. Also, like I said before, I performed a clean install of my entire OS so I'm skeptical to believe that it's corrupted drivers. I'm really at a loss as to what could be the problem, so help from you lovely people would be greatly appreciated.

This is my first post of this kind, so please let me know if any more information is needed.

I'm aware that my system isn't activated, but getting my win7 activation to transfer is rather low on my list of priorities at the moment (at least until my computer stops crashing!). I'm not running any programs like CCleaner, my C: drive has very little on it because I just reformatted it. I do find it quite odd that I don't have crash dumps, though. If it's not producing crash dumps when I black screen does that mean the problem lies more in the hardware?
Thanks for your response, by the way.

1) I monitored the temperature of both my CPU and GPU, but the temperature that I mentioned was for my GPU.
2) No, I haven't. Not sure why I didn't try this.
3) I'm using two monitors, my main one is this and my other one is an old Samsung TV. I disconnected the TV to troubleshoot.
4) I have. The cable looks fine and is securely connected.
5) I've tried 365.19 and 365.10. I started crashing the day 365.19 came out so I thought rolling back to 365.10 would fix the problem but it didn't.

My cpu cooling is this, and my PSU is this. I was a little generous on the wattage to leave room for upgrades and prevent problems like this.

I realize now that this thread is becoming more of a hardware discussion rather than BSOD analysis, so I apologize for putting it in this section.
