That's exactly why I choose not to get that board LePaul. Too many people are having problems with GF 4 cards on that board, indeed with a lot of boards. (VIA, Sis, Intel, all but nVidia it looks like... ) I was having a boot up issue with my old Asus A7V (KT133 chipset) board, but everything works perfect on my new Asus A7N266-C. I hope you get it working LePaul, but if not you might want to consider using this board too. So far I'm very happy with it. Other than the funny little ACR card with the audio ports not being easy to put in, everything has been a snap. (Let me guess, you bought the board because Tom's Hardware recommended it... )
