Hello, 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. I'll list specs below:

Nvidia GTX 570
Intel i5-2500k
8 GB RAM

It's becoming rather annoying and I would really love some feed back. Thanks.
