Windows XP Windows XP Registry Error

[moowithmeidina]

Hi, I recently got my old laptop out of storage to give to my sister, but when I try to boot it I get a message saying there is a registry error. It says STOP: 0x00000051 (0x00000003, 0x00000001, 0x00003000, 0xE11AC030). I've followed the instruction on Microsoft's website by loading the Registry Console, but once I press 1 and Enter at the next screen, instead of asking for the admin password, it goes back to the blue screen with the stop message. Can someone help me out here? I don't care if I have to reformat the harddrive or anything, just tell me what to do to get my computer working again.
