After a while time of playing the
screen becomes black - it looks like that from
the videocard there is no
signal. But the sound is and game
goes further. After pressing
"Alt+Enter" (returning to fullscreen mode/to windowed) picture comes back. But
after that some characteristics
of the videocard (supervision
with help of EVGA Precission X) changes from (this data I got when I played Sleeping Dogs before incidence):
Memory clock 1701 mhz
Gpu clock 550 mhz
And normal 30 fps.
But after incidence with Dolphin, when I try to play in Sleeping Dogs here is another data:
Memory clock 324 mhz
Gpu clock 405 mhz
And only 9 fps.

After rebooting pc games starts normally in full power of videocard, while I again won't start emulator till black screen.

Im using Dolphin 3.5 x64 on Windows 7 x64. My vc is Geforce GT240 (512 mb), not overclocked. Videodriver has version 310.70 WHQL.

Im playing Dolphin many times before, but this problem apears first time.

Maybe GPU overheating . Use Nvidia Inspector to check GPU temp when game is running

Maybe it connected with next error: "Display driver
has stopped working and has
successfuly recovered", which appears only when I playing on Dolphin (with pc games, pcsx2 all is norm)

Nothing changes, when I try dx11 and opengl full of graphical glitches (non playable).

Settings is:

Dx9, internal resolution 2.5x, scaled efb copy set on, ignore format changes set on. Efb copies to texture. Texture cache set fast. External frame buffer set disable. Fog disabled too.
Dualcore set on, idleskip set on, jit recompile, dsp hle emulation for sound, bios skiped.
I hope, its all.

May it depends from concrete game?

I try to play: cursed mountain, endless ocean 2, no more heroes 2, tales of symphonia: dawn of the new world, project zero 2 jpn ver.
