non visible display due to incomplete unistall?

On the advice of a friend I downloaded the new tweakable omega video drivers but instead of uninstalling nvidia driver he removed at add remove programs... on reboot display vanishes behind black wall after windows xp logo is featured but before log on screen. safe mode brought dreaded bsod I was able to log on by typing password and hear the computer logging on but still no display need help getting back from black. last known config etc no help
windows xp pro

ASUS A7N8X deluxe MB
AMD Athlon XP 2600 CPU
512 mhz ddr
fx5200 agp

 

So...how exactly do you get a 'dreaded bsod' if you can hear it logging on in Safe Mode but cannot see anything?

 

I should have stayed with the sequence, scuzi. Blue screen of Death occurred when I attempted safe mode otherwise system boots as described
