Last night, while using my HP laptop (with Windows XP Pro), I experienced a power failure. I did not try to turn the laptop back on until this morning (when power was restored). However, the computer goes to a black screen where I have an option to start using Safe Mode, Safe Mode with Networking, Last Known Configuration and Normal. No matter which option I choose, the laptop just loops back to that screen. I have tried to move the computer to a different area of the house and plug into different outlets to no avail. I am at a complete loss! Can anyone help me? (The last thing I did prior to the power failure was to remove a software program - WinMX and reboot, then about 20 minutes later the power failed.) Thanks!!!
