Hi Orcinus,
My operating system is Windows 7 64 Bit, and a full disk check before has shown no threats. Also, not having this PC long, about a month, ive not downloaded anything other than ArmA 2 Mods such as DayZ and @TCG for playing Island Life.
Under very tight circumstances I can get ArmA 2 OA to launch, by opening the .exe right as the computer loads into the desktop, if it is left any later the symptoms above occur. This is however not convenient for if i want to play DayZ or other mods.
Because of this the game has written new .cfg files. All other large programs run fine EXCEPT Grand Theft Auto 4, which I have consistently had problems with, exact same symptoms to this problem.
Also, how would one find the Windows event viewer logs? Maybe this could find the issue. Thanks for your help so far
