Hello! I have a problem with my system. My screen goes black at random times for 1 sec. Has some pixelating effect also ms before the flick. It has happened with my ASUS r9 270 OC maybe 2 weeks or more. These black outs seem to not be connected to loads, game etc. They do not change system stability, everything is ok. Sound dosen't change, music keeps playing. I use Afterburner and i have 1040/1450 clock, power factor was 15% up. My system spec should be in my profile. Although, the problem remains at stock clock. 975mHz and 1400mHz ram clock CPU i3570k @ 4.2Ghz, have had no issues for 2 years with this clock/settings. Also i have my ram at lower clock than reference? 1333 Mhz. I got system instability when i used 1600 mHz.
