Hi I just moved my system (Asus M2N sli deluxe) to a new Antec computer case, and installed a large Noctua heat sink. Still using the same video card (Asus en7200gs). when I tried to boot up I got the error code. Makes sense b/c I don't get any video. I tried re-seating the video card and tried a different slot. No luck. I just ordered a new video card to try out (I could use the HDMI upgrade anyways), but I have doubts that will fix it based on other inconclusive threads I have read. What else could the problem be? Could it be the new CPU heatsink? Maybe the motherboard is bowed? Anything else I can try?
