Unfortunately the only thing found at Packard Bell without knowing the specific model number is the support page where you choose that and then go from there to see if you find what those codes mean.

The other PB articles and links found are at least 5-6years old and of no value on determining what those codes point at. But you could try a boot from the XP disk and try an "install to repair" method if XP is already on the drive. If the errors are not pointing at the drive but the lack of detection from a corrupted boot sector due to electromagnetic whatever that would be a minor software glitch correctable with the repair method. A code like this after a storm sounds like the board could be what saw damage. To try the repair on the current installation,

One other thought would be the bios information having been effected and possibly the EProms could seen something during the storm itself if the likely line surge happened. Or by simple coincidence something has decided to let go at this time. The one to see whether Windows or a hardware is the problem would be the repair option. If you suddenly see a normal running pc it was a simple glitch of drive information. If not it seems most likely the bios is seeing a failure from either damage or factory defect if the system is rather new.
