x1900xtx screen flashing blank for a second

[obsidianzero]

I started noticing the screen flashing blank for a second just a little while after playing games, Could this be a "side effect" of the switching from 3d to 2d/desktop clockspeeds from the ati drivers or is it a hardware problem? It never happened in game. Is this something I should worry about or?

It does it on my computer after I exit games. X1800 XL. Actually, every card Ive ever had done it. I never worry about it, and you shouldnt either. Not a hardware problem IMO

f.e.a.r. has ran on 1280x1024x32 4x AA rest of the options maxed out for hours.
I think if it was something with the hardware it probably would have occured in game too
