I can't work this one out. I built a machine for a friend-120Gb WD SATA-Asus A7V880 mobo-2Gb RAM and a PNY GEForce card that they had already bought. All was well but they decided soon after to have a better card,I supplied and installed a RADEON9600 Atlantis and now the machine gets through POST and stops with an error message saying Windows cannot load, reinsert the old card and voila XP boots and all is fine. The RADEON is a good card, its fine in my home made PC. Any Ideas ????
It could be a conflict between the Nvidia drivers and the ATI ones. I had a problem when I went from a GeForce card to a Radeon one. There is a program to remove all traces of the old drivers before installing the new ones and this may cure it, unfortunatly I can't remember what its called. But someone on the Forum will surely know and provide a link.
