I used a disckchecker from glaryutilities (technically, it's used via the command prompt, and thus from windows itself). I thought it was enough, since I did it on my own pc. I have NOT had a bsod... lucky, maybe? Especially since I defragged my pc using PC Tool's Performance Toolkit right after! Then, I did the same on my mother's pc for her... but this time the BSOD appeared! The technical info is this: STOP: 0x0000007e (0x0000005, 0xbaadc63f, 0xbacfbc68, 0xbacfb964) I tried FIXBOOT, FIXMBR, BOOTCFG All to no avail... Later, I even ran the diskchecker to fix the problems that it had detected. Via the windows cd (Windows XP Home Edition) I could reformat I suppose, it looks straightforward and simple. But, I NEED to retrieve my mother's files (not many, but VERY important for her). Is there ANYTHING I can do???
