Evo,
With a Hard Drive that is about full and only 128Mb of RAM, it does not matter if the Hard Drive is fragmented or not, it is going to be extremely slow.
Still the best option is adding enough RAM to get the machine to stop accessing the Hard Drive's Swap File. In most cases 512Mb of RAM is enough.
If you want Defrag to work, you should try either Safe Mode, or turn off all the extra processes in Normal Mode, including Anti Virus and Screen Saver, before running Defrag.
Take Care,
Richard
P.S. It would be worth running HJT! on it too. Thanx to Liam, I have found that program to be very useful.
