A few days ago, i was overclocking my graphics card, a 9800gtx. Weirdly, furmark and vantage were fine at 819 core, 2048 shader, and 1250 mem. When i tried farcry 2, it crashed and i got a blue screen. So...i put them down to 800,2000,1200, and then i noticed the monitor would flicker sometimes, the whole screen would go black, and then it would go back to normal, just for a split second. Gradually, the flickering increased in frequency, finally until the screen remained black. I tried another monitor in the same port with the same cable, and it was fine, and i tried the broken one in another computer, using d-sub rather than dvi...the same problem happened. So what i'm wondering is it possible for a graphics card with bad clocks to destroy a monitor?
