    As of late my mac pro seems to have gotten slower. Yesterday it took about 3 minutes just for Safari to open up. I shut down the mac and restarted it and the loading bar was stuck for over an hour. On the 5th restart it decided to work again, but still extremely slow.

    Can anyone give me advice on how to fix this step by step.

    Did you install anything recently (software-hardware)?

    Would help if you could provide more information about your Mac Pro desktop machine, the OSX you're using. 3 minutes for Safari to open up is weird.

    With this limited info, possible failing HDD.

    or the HD is 99% full.
    or you have something doing a lot of HD IO stuff going on in the background like backups or anti virus scans.

    backup all your data is the first thing if the drive is going bad.
    (it's always good to have a backup just in case)

    Recently took it to Apple because i couldn't fix the question mark folder and it was the SSD dying on me. Well we installed the startup software on one of the hard drives and was working fine. Just as of a couple days it has started to drastically slow down. It's currently on the latest Yosemite.

    Even though it's a 840 Evo, and the SSD really suffer from that performance issue. It still has at least 20MB/s reading performance, by considering it still has much lower latency than normal HDD. There is no way that the computer respond in such slow motion. And TRIM may help to improve performance in some case, but not that extreme either.

    So, I think I can safely assume that problem is nothing to do with the 840's design fault, or TRIM related.

    So I haven't touch the Mac Pro in a couple days and today it took over 1 hour to get to the login screen. Any ideas on what it could be?

    I have 3 - 1TB hard drives in there so if the one is dying what do I need to do to fix the issue? Thanks.

    Try doing a clean install of OS X on one of the other drives.

    Replace the faulty one, or at least remove it.

    How do I go about doing that? Obviously I am not super computer smart.

    Step by step please.

    One way would be to make a USB OS X installer. You would need access to another Mac to download the El Capitan installer then make a bootable USB flash drive.

    Once that's done, plug the USB flash drive and hold the Option key while you power up your Mac Pro. When presented with choice of bootable drives, choose the USB flash drive. Then, it's just a matter of following the on screen instructions.

    Download the installer from the App Store. Then search for the freeware app called DiskMaker X to make bootable USB flash drive.

    Thanks for the help. I now have the OS X on the USB. How do I need to start my Mac Pro with the new USB. Thanks.

    1. With your Mac Pro powered off, plug in the USB flash drive to one of its USB ports.
    2. Hold the Option key on your keyboard and power on your Mac Pro.
    3. When you see the drive icons from which you can boot, select the USB flash drive.
    4. Follow the on screen directions to install OS X.

    First remove all of the hard drives apart from the one you want to do a clean install to just so you don't wipe anything you need by accident.

    Hold down ALT when the machine starts and select the USB stick as your boot choice.

    When it loads up (can take a while), choose disk utility from the menu bar and format the drive you want to do a fresh install to. Once it's wiped close disk utility and follow the instructions to install OS X.

    Sit back and let it do its thing.

    If Apple has determined my SSD is dead in the Mac should I remove it or is it fine just sitting there?

    I'd take it out. Whenever you access certain parts of Finder where it needs to do a check on what's connected then it'll be reading the drive which will slow down the system while it does this. I can occasionally hear my non SSD Windows drive fire up now and again, it doesn't cause any performance issues but it could do if it had a problem.

    If I were you'd I'd remove everything other than what you need and discard anything broken. Also if your SSD is dead and you're moving to a spin drive I'd consider buying a new SSD as soon as possible, you're going to notice a horrendous performance decrease.

    Open Disk Utility, show us what options you have.
