Windows XP Home SP2. My PC is running very slowly & I have been advised to format the hard drive & reinstall Windows. The only CD I have is SP1. The XP2on my PC is uptodate. I've also been told that if I remove unwanted programs, save my data files using Acronis True Image Home 9.0 to an external USB hard drive, then defragment the PC's hard drive with only the system, antivirus, firewall & programs I want remaining on it, that that would not make the PC much faster. The only way is to format & reinstall - a real hassle. Is there a quicker way to use TI to help? Any advice would be greatly appreciated.
