I have a Latitude L400 and I installed XP Service Pack 3 in hopes to repair some issues I was having.  I now have too little hard drive space to do anything pretty much and have so little space I cannot delete SP3.  Therefore I tried to do a new install of Windows XP Professional in hopes of starting fresh.  In setup I received an error message stating I do not have enough hard drive space (I believe 1021 MB) to install the operating system, hence my problem.  I would like to know how to "clean up" my hard drive so that I am able "start fresh" with just the basics of Windows XP, nothing more.  It's a 4 GB hard drive and I tried deleting unnecessary programs and have used disk clean up to try to free up enough space.  Please Help!
