hey I am not an expert but I had similar issue with 8800 GT where I get to a point where no AV wizard. I can show you my trick, its not technical but it works.
1. you said, you had your system up and running with your 220 out. if so, get your system up running without 220, hope you will see your basic UI1 on the screen and everything else is fine.
2. from there you want to rerun AV wizard from advance. the system will try to restart. as soon as you see the bios screen turn it off. in other words do not let it completely restart. at this what you want to do is,, put your 220 back in and let it restart. it is the same way as pressing the "shift" key between two beeps unfortunately for some reason my system does not make that beeps so I follow this weird method.
3. now assuming you have 220 card in and your system is trying to restart and it should try to get AV wizard. the problem is the system will try to give the screen from basic connection. in my 8800 GT it was s-video connection. since I had two DVI and one S-video. try to connect all inputs VGA preferable, if not the svideo and it will give you the AV wizard screen.
if you dont see any thing... press 3 wait,,,,,, nothing then try press 4 ,,, wait... for DVIs there is a list for number but for latest it does not corelate and also varies from card to card. after all,, the system will try the basic input on your card first followed by DVI then hDMI... thats how it goes....
I hope my steps make sense to you. please dont give up. you are almost there. as you had it up running once. its just few steps and you will be happy.
let me know, thanks.
