I got my 9800 Pro OC'd to 430/370 with a Koolance water cooler on the GPU, not generating any artifcats, and those frozencpu monster copper ramsinks on the ram. When I first boot, and not every time, all these little lines will move across the screen.. UNTIL, i click or do anything that makes video movement, this will only happen then right after booting and never any other time.. What causes this? I'm just sorta paranoid I dont think it's an actual problem cause I can't recreate it in 3dmark or anything.. Is it cause Rage3d applies the video OC at that time or what??
