I have a Dell laptop with Windows XP. I am getting a blue screen with the message "Page Fault in Non-paged Area; STOP: 0x000000050 (0xC1B00000, 0x00000000, 0x8053A6A3, 0x00000000". When I hit reboot in safe mode, the same message appears. Dell Tech support indicated I need to reload Windows. I would like to recover some of the data on my hard drive. In order to do that, I purchased a SATA USB hard drive enclosure and inserted my hard drive in it. Several PC's that I have plugged this hard drive into go to the blue screen with the same message upon plugging in the USB. A couple of others just reboot over and over again. Is there a way to recover data from my hard drive. Also my Windows OS installation files are on the same hard drive (I do not have an installation CD for this PC). How do I go about reloading windows (I may have Dell help me with this even though my software support has expired. Any help on data recovery and windows reload will be appreciated.
