Hello guys,
I have a Evga GTX 1070Ti black edition graphics card. There is no problem in normal use and everyday work. Shortly after the game, the computer freezes and I''m kick out of the game. When I kicked out, sometimes I get an error(dxgi_error_device_hung). Sometimes the image goes and gpu fans are turning very fast. It happened twice. I''ve tried different nvidia drivers. Nothing changed. I''m telling you once again that there''s no problem with everyday work. The problem is when I enter the game. I just bought my graphics card. I think the problem is with the video card or power supply. What do you think?
 
I tried it today
I installed the Aida64 program. I created an alarm above 75 degrees for the GPU temperature. I got into the game, the alarm rang about 30 seconds later. I did the system stability test with Aida64. Failed. There was a similar problem in the game. The screen goes out and Gpu fans turn 100%.

Thanks. Very kindly
 
My graphics card is new, about 1 month old.  I installed a clean installation after I tried DDU.

Yeah, that psu is suspect.

I tried something different today.  I  clamped the PCE-I (6   2) power cable connected to the video card with my hands. Then I started a system stability test with Aida64. I kept squeezing it with my hands to power cable for about 5 minutes. And yes, the problem is solved. I think the power cord is worn or damaged. I just ordered a new PCI-E power cord. When I test it with the new cable, I will share the results with you. Thank for your help. 

Hope the new cable is compatible with your psu. If it isn't you could fry something.
