The biggest thing you left out of this is the make and model of your graphics card.

IDK how, but the creaters update has caused alot of headaches, and does not perform better in gaming, although that was one of its intended uses.

If your OS is on your SSD, and you're booting to your OS, then your drive is probably fine. If it wasn't, you would have likely gotten a SMART status alert on bootup.

My HDD on my ASUS board doesn't show up on the boot order. It only says SATA HDD, ect. There's another section in there that should say Hard Disk Priority or something like that, where, if you have multiple drives, boot priority for those HDDs is here and not on the main boot selection. Alot of ASUS board BIOS's are setup like this.

Google on how to disable the creators update. Grab the benchmark and see if that runs for you. Make sure your GPU drivers are updated, and if your hardware is overclocked in any way, remove this. Try these things and post back here.

Thanks.
