We apologize for the inconvenience, but Windows did not start successfully. A recent hardware or software change might have caused this. If your computer stopped responding, restarted unexpectedly, or was automatically shut down to protect your files and folders, choose Last Known Good Configuration to revert to the most recent settings that worked. If a previous startup attempt was interrupted due to a power failure or because the Power or Reset button was pressed, or if you aren't sure what caused the problem, choose Start Windows Normally. Safe Mode Safe Mode with Networking Safe Mode with Command Prompt Last Known Good Configuration (your most recent settings that worked) Start Windows Normally Use the up and down arrow keys to move the highlight to your choice. Seconds until Windows starts: 30 After I make a choice windows proceeds to only a blue flash of a screen and the it reboots over and over with the same blue screen. I have a Dell Dim. 4400 with 512mb and 80GB hard drive. Ive tried to boot from the windows cd and windows simply just rebooted to that same blue screen. Ive tried everything and im at the end of my ropes. So someone please help me.
