Get yourself a copy of Acronis True Image and do a clean install including the major programs you need. Then save the image - you can restore this image later in 15 minutes. Why? Because windows XP SP3 RC is out and your system will run faster with it! So its worth doing a clean install of SP2+ your software and saving the image and then adding SP3. In a few months the final SP3 will be available and you can save the SP3 version.
You can run "cleanup" and "repair" programs.. and they are usually effective to a degree. However, XP still needs a fresh install periodically to clean up additional schmutz and to eliminate errors which Windows has accumulated.
Ditto on Acronis. If you can wait for SP3, it might be advisable to postpone doing a fresh OS install. I have a hunch that the "recommended" installation of SP3 will be "immediately after a fresh install of XP and before installing programs". This may not be correct, but I'm going wait.
Linux Boot cd Formatting HD procedures: * dd if=/dev/urandom of=/dev/hda * dd if=/dev/zero of=/dev/hda * dd if=/dev/random of=/dev/hda && dd if=/dev/zero of=/dev/hda (random takes longer than urandom) For the paranoid idiot inside you..Execute all minimum 7x
Did you say "schmutz"? Ha! I love it. Oh, and I agree that nothing beats an occasional clean install.
Of course. And if you do a fresh install, I strongly recommend this software: http://www.nliteos.com/ It lets you configure the install process in many ways.
