On my WinXP Laptop I can boot normally to the Welcome Screen but when I try to login it makes the sound it usually does, the screen blinks, and I am back to the welcome screen again.
I tried to boot in safe mode but that does not work at all. It just fails with a bluescreen that I can't read because right after it appears on the screen the computer shuts down and reboots.
What can I do? Ideally I would like to go back to a restore point.
