files incorrectly name in history folder, after deleting, still no normal startup

I have windows 98 in my laptop and it is not starting up it seems that the
files in the history folder are of the incorrect file name length.

how can I remove these files as just deleting them has not worked, it still
shows up that the files are there after deleting them.
also I have done a delete temp files in the properties of internet explorer.

I can get into safe mode, but it will not start-up normally.

done a disk defrag and a scan disk and surface scan, still not starting up,
what else can I do to get it to work,

thanks in advance for any help given.
