Mouse movement causes FPS drops - which part of my PC is failing?

Hey guys!

I've had my computer for several years now, replacing parts bit by bit. Only recently have I suddenly had the problem where moving my mouse in a game like CS:GO or Rocket League causes FPS to drop from 100ish to 20-30. I've never had this problem before. Using a controller doesn't cause any FPS drops but I feel like the PC isn't performing as well on Rocket League as it used to. Anyway, I changed my mouse's polling rate from 1000Hz to 500Hz and it really helped the issue. However, I still notice frame drops when looking at the FPS counter whilst playing Counter-Strike, when I'm moving my mouse. Switching menus also creates a considerable drop which I don't think I noticed before. There doesn't seem to be anything unusual in Task Manager, each game takes up "40-50%" of the GPU.

With this knowledge, can I determine which component of my PC may be starting to fail? I've tried switching mice and the same problem occurs.

Specs:
Processor - AMD FX-8350, c. 3 years old
RAM - 10GB DDR3, c. 3 years old
Mobo - Gigabyte GA-78LMT-USB3, c. 1.5 years old
Graphics - 2GB Nvidia Geforce GTX 770 (Palit), c. 4/5 years old
Storage - 1TB Seagate HDD, c. 5 years old, 240 GB Kingston SSD, c. 3 years old
PSU - Corsair VS 550, c. 2/3 years old

Static? With plastic? LOL, compressor blows more air and can spin up fans more than regular vacuum cleaner (unless disconnected or wont burn out)

And while doing this to PSU please stop it with wooden stick or something (NOT METAL), i've cleaned it with vacuum and typing right now (if you...


Also add onto this list. Have you reinstalled/reset windows once in those 3 years?

I've tried a clean reinstall of my graphics driver. I need to buy some compressed air to clean the PC which I'll do after the new year, and I have reinstalled/reset windows about a year ago.

The HDD is being "optimised" weekly, I suppose that counts as defragmentation? The SSD hadn't had an optimisation in a month.
I just ran a manual optimisation on my SSD and HDD and it seems to have made a slight improvement.

My PSU is a VS 550.

Not sure, isn't compressed air the best way to handle it? Or is using a vacuum cleaner fine?
 


Vacuuming is a terrible thing to do. It creates a lot of static. I always just use a compressor to blow dust out of my pc.
