Every 1 minute GPU, BUS and FB Usage drops to 0%. Voltage is stable.(IMAGE INCLUDED). It appears for 1 sec and after that it's working fine for ~1 min.
Played Outlast 2 everything was fine. Games with less requirements as cs go are working properly. FPS drops in Hitman, Sniper Ghost warrior 3, Mass Effect Andromeda.
ITS NOT TEMP ISSUE. PC is stable (benchmarking for over 30 mins). Drivers up to date.
