I have an AMD Radeon R7 370 card with 8Gb of system memory. One (my secondary) monitor is connected via VGA and remains stable. The other, main, monitor is connected via HDMI and recently, has been going blank at random intervals. The amount of time the screen is off varies from short periods to quite a long time.
I have been getting screen blanking for very short periods for a while but when this happened, I could hear a clicking sound from the PC.
But with the recent and more serious blanking there has no clicking sound. It happens in silence!
I have checked all cable connections.
Hope someone can help.
