Games stutter all the sudden

Have had the rig for 3 years about a few weeks ago it started as a mouse stutter. Games would run fine but it seemed like the mouse would lock up at certain times. Now the mouse seems fine but games lag. I did a fresh install of Windows 10 and problem still occurs.

Operating System
Windows 10 Home 64-bit
CPU
Intel Core i5 4690K @ 3.50GHz 72 °C
Haswell 22nm Technology
RAM
12.0GB Dual-Channel DDR3 @ 666MHz (9-9-9-24)
Motherboard
Gigabyte Technology Co. Ltd. Z97-HD3P (SOCKET 0) 34 °C
Graphics
VG248 (1920x1080@144Hz)
Intel HD Graphics 4600 (Gigabyte)
4095MB NVIDIA GeForce GTX 970 (NVIDIA) 36 °C
ForceWare version: 390.65
SLI Disabled
Storage

117GB SanDisk SDSSDP128G (SSD) 21 °C

Check CPU/GPU temps while gaming. They can increase over time due to dust buildup, and cause throttling which can show up as stutter. I seriously doubt your 970 GTX is running at 36C under load. If temps are high, make sure all coolers are firmly attached and working.

Manually download and install drivers for all components, even if Windows says there's already a driver (no red Xs or yellow ?s in device manager). Win 10 tends to be overly optimistic about its ability to find appropriate drivers, and will show the "proper" driver is installed even if it doesn't work.

Be careful of programs which are installed as part of a driver package. Some of these are known to cause performance problems and stutter. Intel seems to be pretty...
Did you put a pagefile on the HDD? People with smaller SSDs often do that to try to safe space. Don't. Windows considers pagefile accesses the highest priority (it is basically the same as RAM to the computer), and will literally freeze the mouse and screen if it needs to wait for the HDD to process a pagefile request.

Or to put it another way, disconnect your HDD and try playing the game off of only the SSD. See if that eliminates the stutter.

Any other changes, upgrades, or updates around 3 weeks ago?

I moved Windows 10 to SSD for the first time to see if it would help a couple days ago. When I removed the HDD to try what you said Windows wouldn't boot to the system. The HDD is completely empty as well.

I do not even know what a pagefile is so I dont think I have lol.

In CrystalDiskInfo The HDD health status does come up as "caution". That is the reason I moved the OS to SSD but it didnt fix anything.
 

Ok, the HDD *could* be the cause of the problem if it's health status is caution. Windows tries to set up pagefiles automatically, and in a situation like yours (where the HDD used to be the boot drive) it could still have a pagefile which is causing the problems. It's a hidden system file so doesn't show up by default.

The system not booting without the HDD is a common result of installing Windows with multiple drives connected. The HDD is actually your boot drive (even though nothing is on it). The system is booting off the HDD and the boot sector on it is telling the system that the boot partition is located on the other drive. This boot sector is missing from the SSD, which is why the system won't boot without the HDD.

You need to disconnect the HDD, boot off install media, and run an automated repair to make the SSD bootable. Most of the time that works. Sometimes you have to resort to a manual repair. I assume you have a backup of your data and files? There's an outside possibility the process can totally hose your system.

Once you've booted with only the SSD connected, then we can conclusively eliminate the HDD as a cause.

I got it to boot from SSD, and only have the SSD connected and it still stutters. Its playable, but its not smooth like it used to be.

Have you tried cleaning the mouse's optical port? I've noticed when a hair gets stuck in there, than can cause laggy/stuttery mouse movement.

There's an outside chance your stutter is related to the Meltdown/Spectre patches. I haven't heard much complaining about performance problems related to the patches. But on my computer at least, I've definitely noticed more laggy behavior after getting those patches.
