After I have changed my video card to MSI N770 TF 2GD5/OC, nVidia GeForce, GTX770 is started to blink (turn black for a few seconds) while watching full screen video (with MPC-HC).
The blackouts occur random, but very often tends to occur at the same place of a video. I.e. if rewind then it will appear at the same place in 90% cases (not 100%). These blackouts are not embedded into video, because they do not occur in windowed playback and not occur in 100% in the same place.
Also these blackouts occur while playing fullscreen video games.
Looks like videocard turns of for a few seconds if some video event happen.
No any error messages or log entries appear.
What can it be?
UPDATE
I don't have any overheating, reported by monitoring software.
I don't overclock yet.
My driver is 340.52, which is latest.
My power is 650 W. I can't imagine, how can power problems manifest at specific places of video. I can rewind back a second and have blackout exactly at the same place for dozens of times.
The same blackout occur both in MPC-HC and VLC Player. Playing with rendering options didn't fix the problem.
UPDATE 2
Updating firmware for motherboard ETC didn't help.
UPDATE 3
Also I noticed, that narrow blue horizontal lines are blinking from time to time at the right side of the screen (while watching full screen). This is somehow reminding old-era ELT television screens...
Sorry people, it was just a problem with HDMI cable connection. Never thought bad cable connection can cause such specific glitches as it was...
