Howdy!
Just got a second monitor. Hooked it up and got it all setup
Works like a charm!
However, when I boot into tf2, portal 2, from the depths, or even Worms revolution my screens work fine. It's whenever I actually start getting into things like loading into a server or a map that my screens go black, my audio start repeating itself indefinitely and I can't use any shortcuts to do anything. I have to perform a full system restart. Any help?

My CPU is an old LGA 775 piece of OEM junk. My GPU is an HD Radeon 7570 and my monitors are both LCD televisions. One is on HDMI coming from a display port adapter, and the other is a VGA connection coming from a DCI adapter.
