Random Reboots without BSOD, Windows 10, Can't Pinpoint The Issue

So I've had this rig I've built been rock solid since 2011 until about two months after upgrading from Windows 8.1 to 10. I kept getting random resets while playing a game, watching videos, even clicking through my settings or doing nothing at all! I decided since it went bad two years prior it might be my hard drive, a 1.5 TB Western Digital Caviar Green. So I wiped it and reinstalled windows 10. I get a reset and a warning that my i5-2500k is overheating so I put a almost new coolermaster 212+ Evo on it. Resets persist. I then decided to put another HDD in, and since money is tight, I set up an XBox 360 S 250 GB HDD to run windows and installed 10 on it. Again it resets randomly. I test my two corsair vengeance 4 GB RAM sticks using a physical button on my Asus H67 (I think that's what it is) motherboard called MemOK! It runs the test, and comes back without errors. Still resets, so I remove my Sapphire Radeon HD 6970 graphics card and try again. More reboots. Out of frustration and out of ideas I take the battery out of the motherboard and plan on putting a new one in when I get off work today (I'll update the status after I test that)
I get no BSOD even after disabling the bypass and auto reset by windows so I can get an error code to troubleshoot with.

So here is a rundown of what I've done:
-Wiped and reinstalled Windows 10 on my 1.5 TB Western Digital Caviar Green HDD
-Swapped out my stock Intel CPU heat sink for a Coolermaster Hyper 212+ Evo
-Wiped, Cleaned, converted to GTP a 250 GB XBox 360 S HDD and installed Windows 10 on it

-Disabled the auto-restart (skips the BSOD)

-Checked the two 4 GB Corsair Vengeance RAM with the MemOK! physical button my Asus H67 motherboard
-Removed my Sapphire Radeon HD 6979 graphics card
-Removed my motherboard's lithium battery (will install a new one this evening)

Basically my question is this: Is there anything I could've missed? I believe its got to be a hardware issue but I don't know what it could be at this point.

Any help would be greatly appreciated, this rig is very sentimental to me and I'm on a budget so this is my only means of a computer.

Thanks,
Zack

That is a bit older, of a PSU. I suspect it is time for a new one. I know it is only a matter of time before my TX750 needs replaced, as it is also an older unit.

Cool, my younger brother has a PC he built like maybe a year ago with a 750TX that isn't even half the age of my build, I'll test my rig out with his PSU and see if that solves it. I'll check back in later tonight with an update. Thanks man

Yep it was the power supply, I underclocked my CPU first for a test and had no reboots and then swapped my PSU with a newer one and the problem is fixed! Thank you my friend.

Well bud I posted prematurely I guess because its doing it again. I've taken the graphics card out and installed ram that I knew worked but it still kept rebooting. Its either the motherboard or CPU. The mobo shows no signs of corruption and neither of them are overheating. Do you think the overheat I got the one time before all this started has ruined my CPU? It only did it the one time and I never turned it back on until I installed a new heat sink. Its getting proper voltage, and staying at 40C but still reboots.

I would probably lean towards motherboard, before I did CPU. They tend to fail, before a CPU does. I have only managed to kill a single CPU, a Sempron 145, in 14yrs of building. That was due to low quality PSU dying, and taking it and motherboard out. It was before I learned the importance of PSU quality.
