I've been getting pretty frequent TDRs lately. My GPU is a GTX 760 2GB, and I'm currently using driver 353.06 (I tend to stay up to date).
The symptoms are that once in a while, the game crashes with a "driver stopped responding and has been restarted" message, or the game just crashes (with a "debug / close" dialog) or the game/window just disappears. I have had this happen with many games, from Skyrim to Assassin's Creed IV / AC Unity to Witcher 3 to even Minecraft! It seems random, because sometimes it will crash within the first 5 minutes of playing, while other times it will happen after 45 minutes to an hour.
I have left MSI Afterburner's monitoring window in the background while playing (which is helpful because it graphs various data over the last few minutes) and I cannot correlate the TDRs to a spike in GPU utilization, temperature, memory use, voltage or anything like that. At high load, my GPU temp is around 72 degrees C, and the fan speed is at 75% tops.
I've been able to run a few of the MSI Kombustor 3 stress tests for a long time without problems (the GPU memory burner 2GB, the Lakes of Titan 32X, etc.)
One test that gave me TDRs twice is the PhysX GPU one. But it doesn't seem reliable, just happened twice out of maybe 5 attempts, the other 3 times the test ran for 10 minutes with no TDR. That seems pretty consistent with what I'm seeing from games. However, I set PhysX to only use the CPU in the nvidia control panel before, and it didn't have any impact on TDRs at all (in actual games). So I doubt it is PhysX itself that is the culprit.
Can someone suggest something I haven't already tried? Some troubleshooting I may have missed?
This video card is already the result of an RMA (the first GTX 760 I got crashed Windows even when nothing was running!) and it's out of warranty anyways. I am thinking I may borrow a video card from a friend (a known-good one) to see if TDRs go away before going out any buying another one, but if there was another way to confirm that it's my video card (and that changing it will fix these issues) then I'd like to try.
Thanks in advance,
