I use AOMEI Backupper for this. It's free. All you need to do is install the SSD in the computer and then fire up AOMEI Backupper. Chose the source drive as your current hard drive and the destination drive as the SSD. Chose the clone option and the align option. You don't have to chose sector by sector.
Once the clone is complete turn off the computer, remove your old hard drive and boot the PC. It should boot right from the SSD like nothing ever changed.
