I have a pc with XP Home edition which has stopped responding in respect of windows. I had a message that hal.dll was corrupt in the system32 folder and now it will not load windows at all, so I cannot download any of the utilities which purport to fix this error! On boot up I cannot now enter safe mode either! What I can do it to boot up from the CD with my original Windows disk and then I get the C prompt under the repair function or I have the choice to re-install Windows. So...... unless there is something else I can do...if I re-install Windows, will it delete the directories I had in my C: drive (where windows was installed), or will it just overwrite the windows files? I have some knowledge but not much (I am conscious of what a little knowledge can bring!) All the programs I have installed on the computer I have disks for, but it is the spreadsheets I have and my files for my published websites that are giving me cause for concern.
