I've got massive problems going on here... I'm running Windows XP Pro, and after rebooting the computer after a crash, I am no longer able to properly login. If allowed to boot normally, the computer crashes while loading the Welcome screen, before I even get a chance to login. I've tried not using the Welcome screen, and using the other login method, but it still reboots. I'm able to boot into safe mode with no problems, so I'm able to get online to look for help, but so far I've found nothing helpful. Does anyone have any idea why this might be happening and how I could fix it?
Windows XP Pro, no service packs installed so far as I can find and remember
IBM Aptiva, Model Number 2171-545, S/N AM7D8RY
Upgrades from standard: 160 MB of RAM, LITE-ON LTR-16102B CR-RW drive, NVIDIA GeForce2 MX/MX 400
I haven't installed much in quite a while, but since last reboot I've installed and uninstalled Ares and the East Asian Language Packs.
