Yes you can. The first thing you should do is back up all of your saved information or files including pictures and music you don't want to lose and simply do a Google search on how to install an ssd hard drive. There is a ton of info on the Internet to help anyone do this. Then you need to decide if you want to copy your old drive or do a fresh install of Windows. This will depend on whether you have a copy of Windows on a disk or not and if you don't then you can buy a copy for around $100 but the best and easiest option is to clone the drive if possible and if there isn't any issues with Windows like having a virus or corrupted system files. I hope this helps and remember if you have any questions, then Google is your best friend!
