Hmm...... did you install the VIA 4-in-1 drivers? It might help. Thing with SS7 motherboards is video card problems. So they came up with patches/revised drivers to be able to fix this problem. You should try installing the VIA drivers first and then install the one for the video card. Quite weird though this problem you're having coz' the problem with SS7 mobos is usually with AGP. Anyways, do try my suggestion coz' it might work.
