I get the following error message:
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 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.
Any choice cause the system to hang. Specifically, when trying safe mode, it hangs on agp440.sys.
I have tried repairing with both the HP Recovery CDs and a Windows XP Home Edition installation disc. I have tried Windows Recovery's FIXBOOT command as well.
