Ok, I have a compaq 6300 US with 1.4ghz celeron processor, 256 mb ram, 40gb WD hd, and a geforce 4 mx4000 pci video card. A couple of days ago, when I tried to turn on the computer, it started to load windows, but i got a blue screen and the computer restarted suddenly. It kept looping like that until I turned it off. I tried the recovery discs that came with the computer, but when setup is done loading, I get the same blue screen, only this time, the computer doesn't restart by itself. The screen says: The problem seems to be caused by the following file:ntfs.sys PAGE_FAULT_IN_NON_PAGED_AREA STOP: 0x50 I don't know how to fix this. I tried reseating memory, but that didn't help. It would be nice to do so without reformating the hard drive. Any help would be appreciated.
