Question / Help Some games for some time continue to operate the game a black screen

[BIGWEI]

我的電腦
CPU:i5-3470
GPU:GTX970(gv-n970ixoc)(driver 362.00)
系統:Windows 10 64bit

實況遊戲測試
戰艦世界(directx 9)(黑畫面遊戲持續運作有聲音)
救世者之樹(directx 9)(Tests are normal)
鬥陣特攻(directx 10)(Tests are normal)

測試軟體
OBS Studio 0.15.2
OBS 0.658b

實況模式
nvidia nvenc
quicksync

問題:戰艦世界
測試時間1小時，通常1小時內遊戲就會"黑畫面遊戲持續運作有聲音"必須手動重開機！
剛開始以為是驅動與遊戲問題，調整過後繼續實況測試一樣問題存在！
我嘗試不開實況玩遊戲測試，結果正常玩了好幾小時！
麻煩幫忙修正此問題～

-Live game test-
World of Warships(directx 9)(The continuing operation of the game a black screen with sound)
Tree Of Savior(directx 9)(Tests are normal)
overwatch(directx 10)(Tests are normal)

-Software Testing-
OBS Studio 0.15.2
OBS 0.658b

-Live Mode-
nvidia nvenc
quicksync

problem:World of Warships
Tested for 1 hours, usually within 1 hour of the game will be "black screen game continued operation of a voice" you must manually reboot!
At first I thought the problem is the drive with the game, continue to exist as a live test question after adjustment!
I try not to play the game to open the live test, the results of normal playing for hours!
Trouble to help fix this problem ~
