I have been struggling with this issue for months now. My original video card was a Nvidia GTX460 ... thinking this was the problem I changed it to an ATI Radeon R6850 but to no avail ....same problem. My conclusion is the driver stopping or TDR is the SYMPTOM
of the problem not the cause.
However had a breakthrough today when I caught the "crash" with the Afterburner graphs open .. screen shot is
here
to explain
1 - fired up rfactor racing sim, GPU memory & core speed come up from idle to 1100/860 mhz respectively
2 - 4 seconds later the spinner appears and GPU shoots to 100% as usual then....
3 - 9 seconds later, screen goes blank (but audio still running ok in background)
2 - 2 seconds later screen reappears back at spinner...MSI graph shows GPU usage drops to 0%, memory & core drop back to idle as does voltage. Message on at bottom of screen reads usual driver has stopped responding but has recovered. System then continues
as normal as you can see fro mthe screenshot the program is happily running in the background
System is a Intel i3 CPU 530 @ 2.93mhz with 4gb ram running windows 7 64bit service pack 1. H55m-UD2H motherboard latest F11 firmware. Graphics card is MSI AMD Radeon HD6850 1gb running lates 11.12 drivers. Power supply is a corsair GS600 and the whole PC
is only 12 months old. Memtests show all is ok, voltage test show all ok & you can run furmark graphics test all day too withouth inducing the problem.
Somebody somewhere must know what all this means and what is causing it........
