Toshiba laptop quit running Windows XP after what I believe was either overheating or perhaps a virus. The OS would operate in Safe mode but would lock at the desktop whenever I tried to boot into normal XP. The system would not install any network cards load any devices. I just tried to reformat the HD and made it to 76% but then installation was aborted due to a HD format incomplete message. When retried the installation I am now receiving a HDD password prompt.
