一打开游戏 直接出现HDMI或dp 无信号

[hellish]

启动有时会出现小绿点组成的横线。然后要再次启动才能进入系统。进入系统后一切正常，只有在打开游戏后 要不直接黑屏 要不就是在改变窗口时 比如鼠标拉大窗口或者直接选择全屏都会出现HDMI或者DP 无信号。2个接口我都换了2条线，问题依旧，后用别人的显示器hdmi线转接AGV进入系统，打开游戏也出现黑屏。所以我想问下这个是什么问题。还有我想问下 10700配2060s的电脑 HP才给400w电源有点不地道吧。我也是这次打开盖才看到。

When playing a game, the video signal disappears and the screen goes black. Changed the dp line. hdmi lines are the same。The game can be seen in the game window mode 1024x768. In the game, choose full screen or enlarge the window to lose the video signal prompt, and then the screen goes black.Any game. World of Tanks. War Thunder and other 3d gamesIn addition to games. Everything is normal when watching web videos. There will be a horizontal line when you start the computer, composed of green dots. Then there is no response. Wait for the host switch to restart.
