Important Info If You Have Received a STOP Code
If you received a blue screen error, or stop code, the computer has shut down abruptly to protect itself from data loss. A hardware device, its driver, or related software might have caused this error. If your copy of Windows came with your computer, call the manufacturer of your computer. If you purchased Windows separately from your computer, Microsoft provides support. To find contact info for Microsoft or your computer manufacturer, Contact Support.
If you have experience with computers and want to try to recover from this error, follow the steps provided in the Microsoft article Resolving STOP (Blue Screen) Errors in Windows.
These actions might prevent an error like this from happening again:
Download and install updates and device drivers for your computer from Windows Update.
Scan your computer for computer viruses.
Check your hard disk for errors.
Cause
A driver has called
IoCompleteRequest to ask that an IRP be completed, but the packet has already been completed.
Resolution
This is a tough bug to find because the simplest case -- a driver that attempted to complete its own packet twice -- is usually not the source of the problem. More likely, two separate drivers each believe that they own the packet, and each has attempted to complete it. The first request succeeds, and the second fails, resulting in this bug check.
Tracking down which drivers in the system caused the error is difficult, because the trail of the first driver has been covered by the second. However, the driver stack for the current request can be found by examining the device object fields in each of the stack locations.

Microsoft
To put it simply, the system installed a driver that too precedent over another causing the system to have a conflict. Since it is not known which driver(s) are causing this there is no way we can assist you in correcting it. The only real thing we can suggest is to try a Windows Repair using the XP CD.
