Hi all!
I have an iMac Mid 2010 that I bought around 2012. It was running very well until last year, I guess. I only did a RAM upgrade on this machine (it has 14GB of RAM). I wasn't using this computer for a while (8 months or so) and now I got a job that I need to do on this machine. It was stable and running smoothly as I recall last year or two years ago. I recorded / produced some music on this machine with Logic Pro X without having performance problems. I was able to open more than 40 tabs on Chrome without slowing down the system as well. But now, I don't know what happened, it became very sluggish. There's delay / lag while performing simple tasks like scrolling down a long page on Chrome and it's almost impossible to use it for multitasking. Well, it's not even possible to use it only to browse the web (I tried to use Google Chrome with 12 tabs opened and things went south). I'm so sad because last week I told a friend that my 2010 iMac was flying and that this would be impossible in an old PC running Windows.
The HD was almost full, it only had 10 GB free so I got an external hard drive and moved some stuff to free up space. Now it has 250 GB free. I thought that freeing up space could solve the problem, but the performance actually got worse. I did two scans with CleanMyMac and now I repaired disk permissions with DiskUtility. And I don't know what else to do. I'm thinking about doing a fresh install. So here are my questions:
I don't have any money to upgrade to a new machine or even to upgrade stuff on this machine (I was thinking about putting a SSD on it but I would had to send this computer to a professional to do that and that would be very costly).
Well, I think that's it. If you have any suggestions or if you've been through this please reply!
Thanks everyone in advance!
TL;DR: My iMac 2010 was a fast and reliable computer until recently. I would like to know if I should do a fresh install and which OS version runs better with this iMac model (21.5-inch, Mid 2010 / 3,2 GHz Intel Core i3 / 14 GB RAM)

And I don't know what else to do. I'm thinking about doing a fresh install. So here are my questions:
— As for possible causes of loss of performance, anyone has any guess? Should I try to find out possible causes before doing a fresh install? Should I run a speed test to check where's the trouble (HD, CPU, RAM)?
— Is there such a thing as "the best" or "most stable" OS for an iMac? I'd love to know that before doing a fresh install. I'm running Yosemite (10.10.5). As I said above, this OS was running smoothly for some years. I don't know if it's "healthy" (performance-wise) to run an old OS with updated software on it. I felt that after updating Chrome to the last version things got really bad (I've updated some other softwares to their last versions as well). Does this makes any sense? Does it makes sense to use an old OS with older software (maybe they're optimized or run better with an old OS, I don't know?)
