Computer Randomly Reboots (Sometimes BSOD)

[xcaptaintjx]

so ive been having random reboots for the past 2-4 weeks sometimes it freezes then bsod (DPC watchdog Violation) then restarts
and sometimes it just freezes and then restarts no bsod
sometimes one of my monitors goes completely black before going to bsod or restarting as well
it mainly happens when gaming it seems to be completely random tho and has happened a few times while browsing the web
ive used bluescreenview and it appears that it was caused by
dxgmms1.sys (showed up in 1 minidump Files)
nvlddmkm.sys (showed up in 1 minidump Files)
ntoskrnl.exe (showed up in 4 minidump Files)

here is my minidump folder:

PC specs:
https://pcpartpicker.com/user/xcaptaintjx/saved/ZtDNNG
(built my PC in mid 2016) (also my mobo is refurbished from amazon, its the only part that i bought refurbished)
also idk if this will help but i have an xbox one controller, logitech g105 keybored, logitect g430 headset, and a utech smart venus 16400DPI mmo gaming mouse, and these speakers

Things Ive tried
I let Memtest86 run overnight it did 4 passes without any errors
Ive replaced my cpu's thermal paste, (this made it restart less often and dropped my temps dramatically. up till now it had the thermal paste that was on the stock cooler by default)
Ive stressed tested my cpu with prime95
Ive Used furmark to run a stress test on my gpu for about 30-45 minutes
Ive Used error checking on my C: and D: drive in the tools section of the properties and repaired the errors it found
Ive taken my computer apart dusted it and put it back together
Ive reset my bios to optimized defualts
Ive ran virus scans
Ive Refreshed windows 8
Ive Formated my C: drive (SSD) and reinstalled windows 8

Things Ive yet to try
I have not formated my D: drive (Hard Drive) as it has all my documents pictures videos etc etc on it
I have not updated my bios since i bought Mobo (MSI's website only has like 1 update released for my mobo so i figured it wasnt that big a deal)
I have not replaced my CMOS battery
I have not tried a new power supply (i plan to buy one on the first and swap it out to see if thats the issue, if that doesnt fix it ill pry replace my mobo and hope that fixes it)

If anyone can help me i would Appreciate it
Also is there any possibility its my GPU, i really cant afford to replace it especially with the prices how they are now, It should still be under manufacturer warranty but i don't wanna send it back for a replacement unless im 100% sure its causing the issue.

Most likely causes:

- Malfunctioning video card drivers. Boot into safe mode with networking, download and use DDU to remove all GPU drivers, boot into normal Windows and use nVIDIA autodetect to install latest drivers. Do not use Geforce Experience and do not install anything but the display driver and Physx. Another trick is after DDU do not install drivers and use the PC in low resolution mode for a few days or leave it for a few days with things running.

- Overheating. Post your Max CPU and GPU temps when you use stress tests tools. Get these numbers from HWInfo. Furmark and Prime95 are good stress tools, use them for this.

- Bad Windows 8 update. Try reinstalling Windows 8 again. Get your GPU drivers on a flash drive as well. Do the installation with the Ethernet unplugged. Disable Windows update service completely and install the GPU drivers. Connect to the web and use it for a few days. See if it crashes with a fresh Windows 8 install with no updates. Recommend installing a few basics like Chrome/Firefox and an antivirus program.

- Failing motherboard. AM3+ FX boards are known to have bad electrical issues. Very poor quality. Refurbished as well....
- Failing GPU.
- Failing PSU.

It's not: CMOS battery, other HDD, RAM. Recommend you try a BIOS update as well. If we get to the point where it's either the PSU, motherboard, or GPU and you don't have spare parts, take it to a shop and have then run diagnostics for you. Do not buy parts guessing which one will fix the issue. You will not be able to tell with hardware issues what is the problem part without swapping parts.
