I was in the middle of playing BC2 when all of a sudden my entire screen except for the HUD info went black. You can't see the play, the scenery or anything except for the hud. Has anyone else have this problem. I did not run into this problem prior to installing my second card but I have also updated the drivers since. I tried a single 5850 and no problem but two and it happens. It doesn't happen often but now and then and it can be ended by Alt-Tabing out and then back in. Any thoughts? My specs are listed below.
