Okay, so I turn my comptuer on today, and the video randomly sends blanks. I thought it was just my video card going to stand by at first and then the mouse got tapped or something, but it keep doing it. Now my setup is my comptuer to a monitor switch (an old on) then the monitor. I have another computer on it too. Now, I'm wondering, is it my video card, my switch, or monitor. I'm going to redo all the wiring soon, so it someone thinks it's the swtich (which your guess is as good as mine) then I might as well put the 2nd comptuer else were...I hope someone can help me, k, thx, bye.
