black screens in AAPG
 

Hey guys i run an i5 3570 3.8 with 8Gb mem with a Gforce GTX 660Ti. I ve been having black screens , with that i mean my screen goes black for 2 secs and just comes back , it does happend frequently like once a minute sometimes it takes longer. Ive checked for driverupdates but i have the latest.Ive also dowend every grafic setting ingame and check the resolution is the same as my screen ( it says native ). Ive run a Furmark test and it gives 79 degrees tops after running for 5 min. Any idea's on how to resolve this?
Kind regards Barts
