Possibly silly question here. Please help!

About 6 months ago I bought an Apple Certified refurb MBP. An early 2013 model. Long story short, I worked for about 5 months on it with faulty RAM and faulty SSD. This was due to my local Apple store not correctly repairing my computer when I brought it to them. I was experiencing crashing applications, terribly slow performance, glitching GUI's for plugins. It was hell, but I had to work on very time sensitive projects so I just kind of powered through and kept working until they finally fixed my computer properly. Now, I finally have a 100% working MBP. All the hardware is good, and the hard drive was completely wiped and I have a like new, fresh installed OS as if I just bought the computer. Here's my question! Will restoring from my backup of those 5 months worth of work damage the computer in any way? I've heard using a computer with RAM issues can ruin system files. I know that would be software damage, but could trying to run something like that cause hardware to overwork somehow or cause hardware damage in any way? My plan was to create another partition on my MBP hard drive to restore the old backup. That way I could have a fresh partition that I could have a clean computer to start from scratch on, and also the old one that I could reference periodically. I would like to keep them separated.
