Currently running a GTX970 on an xfx nforce 780i sli
core2quad Q9550
4x1gigs G.Skill kit
evga 80 600w psu
windows 10 64-bit home

this was a handmedown system for my nephews. problem occurs 1-2 hours of power-ed on time, whether its idle or running games the system either completely freezes and/or display shuts off and I'm forced to cut power and power it back on. event viewer shows around 12 errors back-to-back "Display driver nvlddmkm stopped responding and has successfully recovered."

*swapped out 3 different power supplies, current one is the newest one with problem still occuring
*swapped out CPU for E8400, problem still occured so swapped back
*swapped motherboard for another xfx 780i sli board, problem still occured
*swapped GTX760 for the GTX970 problem still occurs
*swapped all 4 GB ram sticks for 4 others, still occurs
*formatted drive, reinstalled windows. no change
*used DDU and reinstalled latest drivers, still occurs
*added 64-bit TdrDelay 8 to driver in registry edit, problem still occurs
*double checked GPU seating and PSU cables
*made sure maximum performance was enabled for PCI-E
*updated BIOS to P09

The only thing I can think of is the PCI-E 2.0 is conflicting somehow with pci-e 3.0 GPUs even though they are backwards compatible. have not tried a legacy driver, but I doubt this will work.

any experienced help is appreciated.

1| You didn't mention the OS you're on.

2| Pertaining to ram, what are the sticks of ram? Are they identical? From a kit?

3| In all honesty you shouldn't be able to be able to power up off of a GTX970 seeing how they need a UEFI BIOS environment to boot up. That being said, the error code you've mentioned indicates that the drivers are at fault. You will need to reinstall your drivers with previous(perhaps much older revisions of) drivers to see if the GPU is stable.

Does the issue crop up after breadboarding?

1. windows 10 64-bit home.
2. 4 sticks of 1GB g.skill identical
3. the 970 requires UEFI BIOS environment? the 760 too? problem persists on that card as well. 3.0 cards are backwards compatible to 2.0 so that seems counter productive.
I have no experience bread-boarding PC components

the issue was in fact the compatibility with the UFEI video card on the old motherboard. the fact that I was seeing the same symptoms on the 760 before replacing the motherboard must have been a coincidence. computer is running fine with the new board and 760 on windows 10.
