I just installed a PCI graphics card on my computer. I am running XP. I used to have an AGP card, but it started to get funky on me. So I replaced it. The new card is great, but when I start up my computer with the new card, I don't get an image on my monitor until it has gotten into the windows login. I used to get an image at the startup and post (where I could go into BIOS) at start up. Now I don't, any advice?
