Would I also be correct in saying that you no longer get the "Black screens" and now only the random lockups?
It could be possible that there are two independent issues here and wondering if you may have addressed one of them already...
This may NOT be related BUT: IMO it seems to have something to do with static electricity issues. I get lockups also occasionally when it "seems" my O/C isn't stable... even when the settings are "known stable". The strange thing is that the O/C could be stable for days/weeks and then all of a sudden for whatever reason it isn't anymore.. Shutting down/rebooting doesn't always help as it will start to lock up when loading the desktop. I learned that there is a "trick" to "fixing" it when this happens, I discovered sort of by accident... If I just reboot/reset or even shut down the system it doesn't always help however if I literally shut down then UNPLUG the power supply from the wall, press the power button on the PC (to in theory discharge any capacitors but could be placebo) plug it back in and start up the PC, I get a "overclock has failed message", I ignore it and then just reboot the system where it re-loads my O/C settings and then it is fine again for weeks. If I do this when I lock up, 100% of the time the next boot works just fine with the exact same O/C settings.
This time of year the static is everywhere being so dry and I have a habit of touching the case (mine is metal) to discharge any static before I touch any of the components inside. I get the "zap" when I touch the case... or sometimes when plugging in a USB drive... and if the PC was running that "zap" will usually lead to instability/locks.. it may take a few minutes or be instant but I find that in almost all cases I need to shut down, unplug from the wall, discharge and start over to return things to normal. I can't explain why unplugging/plugging clear this static issue (maybe someone else can) but this has happened to me so many times now it isn't a fluke and the "fix" is consistent for me. This only started this winter when it became super dry here.
I'm still getting the lock up followed by the black screens. The black screens happen because the system locks up. The interesting thing is that event viewer still records the nvidia error if I am not there when it locks up and sits for awhile. The error is an "nvidia driver has stopped responding and has restarted", and it shows in event viewer like ever few seconds so if it sits for a few hours there are hundreds of those errors. So the system is running but everything is frozen.
Note that if I am at my computer when it happens first things start acting weird then everything on the screens freeze including anything video wise, the program showing fan speeds and temps, and the mouse. The backlighting on the keyboard also stops responding. I reset the system and boot it back up, but there is nothing in event viewer except for the alert that the system was restarted without completely shutting down first.
Also it is not static. I thought the same exact thing like 2 years ago when it first started happening. But it has been happening for about 2 years going through all the seasons from the cold and static laden weather to the higher humidity non static laden weather.

Going to go through the painfull process of swapping PSU with another one I have in another PC.
If problem still exists then i am starting to feel its something on the board ? another thing i have noticed that plugging in USB devices into back of M/B locks the PC up sometimes ????
I once though I was also getting the lockups whenever I would jar my desk enough for things on top to rattle because it seemed to happen twice, but those times must've been by chance because I am unable to reproduce the effect.
If you get these lockups when you jar your system or some other means and you can recreate the lockups when you do those things then you have a different problem than I do. But I have also thought it is an issue on the board.
