ok, i installed some drivers for my monitor and for some reason when i play bf9142/desert combat it will keep flickeringmaking everything disapear except for the other player, kinda like a wall hack, qhy is it doing this? im still having problems with my screen going black after a period of time, some people say it overheats, need better power supply, could be dusty, not recognizing the monitor or video card. which is it?
