You often observe that as soon as you start your Windows XP computer after an unexpected power outage, chkdsk starts running. If you allow it to complete, normally it won't run at the next reboot. But if you find chkdsk running each time you start the computer, the problem can be more critical than what it appears.

Registry hive might be corrupted and you might need to reinstall Windows from scratch. This solution in-turn necessitates the need for Windows Data Recovery tools, especially when there is no or incomplete data backup available.

After a brief overview of the problem, here is a specific example that illustrates the same issue. Let's say, you upgrade your computer to use Windows XP Professional or Home Edition. Now, when you boot your computer, chkdsk runs. The problem might be ignorable, but this runs each time you boot-up your computer, irrespective of whether the last shutdown has been clean or unclean.

Explanation

The above problem is most likely to occur if one of the below mentioned conditions is true:

You are using a Hewlett Packard (HP) ScanJet 5100c scanner. Since Hewlett Packard provides a different driver to be used with this scanner on Windows XP versions mentioned above, this problem can root if the specific driver has not been updated yet.

Software registry hive or System registry hive is corrupted.

User Action

Try disconnecting the Hewlett Packard (HP) ScanJet 5100c scanner from the computer and check if the issue still persists. If the issue doesn't continue, you need to update the driver required for your scanner. In other situations, your registry hive might be corrupted.

Boot your computer using Windows XP install CD, backup the original registry files to a temporary folder, and copy them from the repair folder to the System32\Config folder.

If copying the registry hive doesn't work, the last resort is to reinstall Windows and restore lost data from backup. But in case your backup falls short of restoring, use a windows data recovery software. Using powerful scanning algorithms, a Windows Data Recovery tool can help you recover all lost files and folders, and saving them at a safe location.
