Yellow Triangle with Exclamation Point Icon in Task bar.

Solution
Open Control Panel.
Click on System.
In the upper left, click on Device Manager.
Something on that window should have the same yellow triangle.

It is most likely missing a driver is my guess. But it could be that some piece of hardware has failed.
Clicking dosen't work.
it won't react or did anything when i click on it.
it just disappear when i close the software or game i am running.
i think there is something wrong with the driver.
