Hello. I need serious help. 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 This message appeared. I have a Acer Extensa 2000 laptop and I have tried everything. I do not have XP CD recovery. PLease HELP ME!
