I have a HP pavillion 6623 system,having problems with the video. I can't get it to stay on the new video card, it keeps switching back to the old setting. I've done a total format the reinstall everything , done a system restore pulled the video card out and reseated it , I also uninstalled the old one . So now need to know the procedure for disabling the onboard video ? Maybe that solve my problem ? The video card is a Geforce 2 32meg.
