Sorry for the dumb question but I'm looking for a specific answer. I think I may need to build a new PC if the results come in from a guy that I'm having look at it aren't good. I may as well buy a new SSD with a new OS, but. I been using a HDD for everything else, steam, games, download, ect. Will I be able to hook it up to a new system without complications? I really can't afford to lose 500 GB worth. Would it be wise to just get Win10 or just stick with 7?
