I recently formatted my harddrive and reloaded all of my software. I installed Win 98SE and upgraded to XP Home. I got all of my other essential software loaded up and the computer worked fine for at least 1 week. The system locked up the other day after my kid loaded a game and I needed to turn if off. Now when I start it up, it stops at the Dell logo screen and stays there. I have tried to boot it from a floppy recovery disk and a cd recovery disk. Neither drive engages. I have power and the monitor works. Any suggestions?
