After installing card, my system will not recognize that the card is installed. Removed new 4890 reinstalled 3870 that been in my system for a while everything works normal. Installed new 4890 a 2nd time and used an old pci card so I could see if system was working properly. Checked BIOS PCIx is still set as primary card, skips the new 4890 and loads old pci card. Once Vista starts I go to Device manager, vista only see's standard VGA adapter. The new card is powered and fan is on. Any suggestions or just rma the thing?
