I'm having trouble with several games opening their pre-game menus properly but then disappearing. They are running in the background but can only be seen in task manager and do not appear on the task bar. I have had this problem with multiple different games from different publishers so I'm assuming it is an error on my end. The games I have tried are Starcraft 2, Half-life, and a multitude of Steam games. I have a self-built computer running Windows 7

Please help.

I didn't find the right solution from the Internet.
