a week ago this computer started acting a little nuts. Out of the blue, it would say the c: is running out of space. It generally goes down to about 100mb left, but it has gone down to 0 - 10mb several times. No viruses, scan disk, didn't find anything, defragmenting didn't help. I am considering reinstalling XP...If that doesn't work then I assume my harddrive is dying. Any help?
