So I have been trying to get ARMA 2 to launch ALL DAY and all I have been able to do is crash my computer over and over and over. Finally, after using a friends video settings, i play the tutorial. Then I go into campaign and then while we are on the ship, my TV turns black followed by "No Signal". This has been happening all day. Either that happens, or ARMA minimizes and gives me no cursor, forcing me to CTRL ALT DLT my way out. Which then after that, STEAM wont launch until i reset my entire computer. Why is my game being so stupid? Specs: GPU: GeForce GTX 660 CPU: AMD A4-3400 APU with Radeon HD Graphics Memory: 8GB OS: Windows 7
