Hi people, I am having major trouble with my computer. Yesterday windows had some sort of fatal error somehow code c000021a or something like that. My primary objective is to make sure all of my files on my harddrive are backed up before i can re-install XP. My dad is a computer support technician and tried all sorts of ways to try and backup my files. Up until now, my dad has installed a second copy of XP on my laptop and used "Winternals" to access my old files and tried to move them onto the working copy of XP. I managed to get all i needed moved onto the new copy of XP and when i restart and boot up this copy of XP and try to open the files, in most cases I am denied from them...with all kinds of files I am getting messages like Access is denied...the file is currently being used by another program access denied...etc etc...I know that the files are not being used by other programs etc, but they still dont allow me access. Can anyone please help me on this asap ? Thanks.
