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)

 

Operating System

Windows 7 Ultimate N 64-bit SP1

 

CPU

Intel Core i7 4790 @ 3.60GHz

Haswell 22nm Technology

 

RAM

32.0GB Dual-Channel DDR3 @ 799MHz

 

Motherboard

Gigabyte Technology Co. Ltd. Z97X-SLI-CF (SOCKET 0)

 

Displays

2nd monitor (connected using original DVI cable)

BenQ GL2450 (1920x1080@60Hz)

 

Graphics

ATI AMD Radeon (TM) R9 390 Series

Manufacturer ATI

Model AMD Radeon R9 390 Series

Device ID 1002-67B1

Revision 81

Subvendor ASUStek Computer Inc (1043)

Current Performance Level Level 0

GPU Clock 1050.0 MHz

Driver version 15.300.1025.0

BIOS Version 115-671GPI0-100

 

Power Supply

EVGA SuperNova NEX750B

 

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

 

Uwe
