Windoze XP Pro. Tried to install a new video card w/ DVI support for my new Dell monitor. They looked up my system and recommended this card. Nvidia 2400XT AGP 256MB DDDT It goes through the Dell bios load screen, the Windows loading screen, then it goes to a blue screen w/ nothing but a mouse cursor that is way oversized (like if you turned it on to grandma resolution). Tried messing w/ drivers, disabling the motherboard video card. Updated to latest bios. Blue screen. If I pull out the new card, system boots normally. Any idea? The Dell guy said it could be a defective card. But it works for the bios and Windoze screens. Thanks!
