Sorry to ask yet another question, but I'm trying to install a GeForce FX 5200 PCI video card. I have had the same problem before, but need would like to fix it permanently. After installing the drivers (updated for my pc from dell.com, too), a restart with the card in fails. Everything works well until the Windows XP splash screen disappears, at which point the screen goes black and the power light on the monitor turns from green to amber. What am I doing wrong?
