So, I logged into Safe Mode and it worked. I uninstalled the Nvidia Display Driver, and now XP don't freeze on the loading screen, but on the blue alternate log-on screen, without the 'log-on' box.
In Safe Mode, everything works. I really need to get this fixed, since I wrote a 4-page, 1000 word essay on why someone became religious.
My GFX card is a 8800GTS, and I have a GA-8N-SLI Pro mobo. Please, help me get this fixed!
ALL HELP APPRECIATED!
