Question Video output to monitor randomly stops ?

[Metelskki]

This problem is happening after 8 months, suddenly i don't have any video output to the monitor, but after about 15s the video signal comes back.
When the video is back again, some games have a DirectX problem and game closes itself.
I already change my PSU but the problem continues.
The problem happens randomly, isn't in game or in high temperatures.

PC specs:

ASUS B250 G GAMING
Intel i7-7700
GTX 1080 TI AMP EXTREME
RAM: 16GB Crucial Ballistix 2400MHz
PSU: EVGA 600W

More information needed.

When games have a DirectX problem what pop-up window or error appears?

What version DirectX are you using?

What games have the problem? What games do not?

GPU: make, model, memory?

Look in Reliability History and Event Viewer.

Do you see any error codes, warnings, or even informational events that correspond with the times that the video output disappears?

Try another known working video cable.
