I find it really hard to believe that it was windows which "broke" the hard drive, but that's beside the point. You shouldn't consider moving to windows 10, you should seriously DO IT. Like the moment your new SSD arrives. AFAIK you can still use your windows 7 key to install and activate windows10 for free - just make sure you're using the same version as your W7 (so W10 Home for W7Home key, or W10Pro for W7Pro key). While at it, might as well make a microsoft account and tie your license there - it's super convenient when changing hardware. Windows 7 is End-of-life since over half a year now - which means new found system vulnerabilities aren't being patched, which leaves you open game for hacking by botnets exploiting those vulnerabilities.
Also W10 allegedly has tons of improvements under the hood and runs games faster. Didn't benchmark but probably someone on the internet did. Seriously. Upgrade.
