Why does the picture disappear on the video card under load?

Question

GPGPU

On the desktop, it rarely disappears once every 10-15 minutes, but it only costs to load the gpu (DotA at different graphics settings from low to high), the image disappears immediately after 1-10 seconds, then returns after 5-10 seconds, and so repeats periodically.
Video amd 6950
the problem is not dependent on the OS, and in ubuntu 16.04 and win10 everything is also
the gpu temperature is not higher than 65 degrees.
tried to reduce the frequency to a minimum - it did not work
. video driver error messages are not displayed.

Answer 1

Maybe the capacitors are swollen? Maybe there is a bad connection somewhere and when heated it goes away. Take it in for repair to "warm up".
