      Hello

       

      I have an issue with my 2nd monitor which drives me crazy as he goes black for a few seconds and then turns on again, without any error (like no signal found or something similar)

       

      Here the specs of my system

       

      Motherboard

      Manufacturer Gigabyte Technology Co. Ltd.

      Model Z97X-SLI-CF (SOCKET 0)

      Intel Core i7 4790 @ 3.60GHz

      So far I have tried a different DVI cable, a different monitor and checked on a updated driver (apparently i have the last version) but noting has helped

       

      The weird thing is that this happens even during the time that the pc is not doing anything and it is totally random. Sometimes it stays on for hours, even when i work on heavy 3D files using 3ds max.

      And then it starts again without any warning.

      I've also checked on the temperature, which usually stays between 45 - 50 °C

       

      Anyone has an idea what could cause this and what i could do to get it fixed?

       

      Thanks
