At any other time, this type of BSOD [Blue Screen Of Death] signals some kind of hardware failure, like a hard drive crashing. But after an improper shutdown like a power outage, it usually means that the Windows file system has been corrupted.
If your C: drive [or wherever you've installed Windows] is formatted in the FAT32 file system, then it can be particularly susceptible to this. It is better for users of newer operating systems to format their drives in NTFS. After all, prevention of the problem is better than a cure.
Fortunately, this can be easily solved. All you need to have is your Windows XP installation disk.
o Insert the CD into your CDROM and boot your PC from it. You might have to configure your system BIOS to do so. o When the blue "Welcome to the Installation" screen shows up, press [R] to select the "Repair" option.
o If you're prompted for an administrator's password, enter it.
If there isn't any password, just hit [Enter] key.
o A black command prompt screen will be seen next. Type in "chkdsk/r" and hit [Enter] The Chkdsk utility will locate and repair the damaged clusters.
o Type in "chkdsk/p" and hit [Enter] This checks the disk's health status and notifies you accordingly.
o Once the checking is done, type in "exit", and restart your PC .
