i tested RAM TEST by KARHU and no errors in 24 hours. Ram its fine , i think. Gpu not crashed because its not driver crash,even not app crash in event logs.
Game not crashed because there is not app crash in event viewer,and no bsod. Game just hanging + music in background from GAME is on + i cant move with character,character is freezed. So yeah in some way its crash. But i think resolved. Its because random EPIC LAUNCHER notifications in down right corner pops up making game hanging. But still unsure.
Today for example game was running 24 hours without issue.
