Constant Stuttering in most games

Hey everyone,

I am having some problems with freezing and stuttering on my computer. I'll be playing at 60 fps, and it'll drop down to about 21-23 fps. This number is almost always constant. This happens in most every game I've been playing recently(Black Desert Online, Forza Horizon 4, Verdun). I can't speak for BDO or FH4, but Verdun I played a little while back, and I did not have any stuttering whatsoever, even on max graphics. The catch? Lowering settings doesn't really do anything for performance. Still a locked 60, but is determined to drop to 21-23 fps no matter what occasionally. I turned BDO from very high to very low, and even with the iPhone graphics, it will still drop from a locked 60 fps to an agonizing 21-23.

Background on computer:
CPU: i5-6500, bought from a friend recently, good condition(upgrade from i3-6100)
MB: MSI Z170A PC Mate, bought from the same friend, for that CPU(upgrade from H100MHDS)
GPU: RX 470 STRIX 4GB, one of the fans has a broken sleeve bearing, so it doesn't spin very well
SSD: Brand new, mx500 250 GB, 150GB free
HDD: 2 years old, seagate 1TB, 120 GB free
PSU: EVGA, 450W
RAM: 16GB, Crucial

Things I have looked into:
Ran a 3 hour prime-95 stability test for CPU, no errors
GPU and CPU running at stable temps while under load, <50 C
Ran drive health checks on both drives, and latest firmware for SSD
Updated CPU and GPU drivers, windows update
Ran full scans with Norton, Malwarebytes, and adwcleaner(to eliminate possibility of cryptomining)
Ran Memtest to insure memory is working fine
Furmark GPU Benchmark, GPU is mysteriously performing at only 63% of the average(why???)


I'm just at a loss here. With task manager open I can see that these games aren't using more than 70% of my CPU, and 60% of RAM/GPU. The programs I have running in the system tray are Norton, Malwarebytes, Steam, Discord, Afterburner, Synapse, and iCUE. This doesn't seem like having a lot of programs open to me, which makes me think it's hardware-related. Another thing that's a tad confusing is the Furmark benchmark I ran on my GPU. It put my score at around 2500, while the average for an RX 470 is about 4000? Not sure what that means, either. I have a small stack of bills to pay for right now, but I will be replacing the GPU in about 2 months(it's getting old, and I would like a working fan), but I'm not sure if the power supply is super under-powered for my system? Not that I'm running an enthusiast build here, but I have an RGB keyboard, headset, mouse, mouse pad, and WiFi dongle, and a PC on 450W. Not sure what to do here, but would prefer if I didn't have to spend a bunch of extra money replacing parts and such. Just curious if anybody had any suggestions; I would be more than willing to try them. :D

So, when I had built this computer, I flashed an ISO image on to a disk and sorta kinda installed it that way. I wasn't running a legit copy of Windows, but other than it occasionally bugging me to spend $100 on a product key, it was fine. Every since upgrading the motherboard, though, it's saying that I have Windows 10 home now. How would I go about reinstalling?
