"Windows did not start successfully. A recent hardware or software download may have caused this.
If the computer stopped responding, restarted unexpectedly, or was automatically shut down to protect files or folders, choose Last Known Good Configuration.
If a previous start attempt was interrupted due to a power failure or because power reset button was pressed, or if you're not sure what caused the problem, choose restart normal.

System will restart in ___ seconds."
I have tried all options offered. I have tried force shutdown and then reboot. Each time (except the safe mode options), it appears as though Windows is resarting, Windows logo appears, then within a few seconds "power savor" sign, then dark, then brings me back to the above message. When I tried all safe mode options, it presents a "list", then goes into the repeated startup.
I followed the repair installation instructions found elsewhere in these forums and am now stuck because I only have a Windows XP Upgrade CD and the system is now requesting a "valid Windows CD". Should I go buy the full version of 7? Will this method keep me from losing my data??
