My video card's stock fan recently died so I ran it for the longest time with just a floor fan on my computer but eventually i decided to replace the fan so i went out and bought a new heatsink/fan. After many attempts I couldnt get it to work so I switched back to the stock heatsink and now im getting poor video. I have OC'd the card before back when the stock fan was actually working. Currently have the 6.14.0010.6575 driver of ATI. Here are some Pictures to show my problem. Also to state everything is plugged in correctly.
