FPS Problem (Major Spikes/Drops)

I have a problem that I am unaware of how to fix it. So I usually play most of my games like for example CS:GO above 80+ fps average on medium-high settings (with normal resolution), and League of Legends on 140+ fps high settings, and NBA 2K16 on 40-60+ fps high settings. Now all of a sudden my FPS dropped to anything below 30. I have to play CS:GO on 800x600 resolution with the lowest possible settings, NBA (which I deleted because it is unplayable at this point), and other games with major FPS drops. I don't know what caused this to happen all of a sudden, but I kept my task manager and MSI Afterburner open to check the CPU and GPU usage and it was spiking up to 80 average and 100 max usage for both. I'm sure I don't have any viruses as I did a full 5 hour scan with Windows Defender and a scan with Avast, and also used CCleaner to clean up a bunch of files and delete junk and any harmful malware. At this point it has been affecting me as I cannot play any games. I use old hardware (and bare mind I haven't cleaned my PC of its dust collection for a long time) however the games I play don't require modern hardware in order to play it at a minimal FPS rate. Can anyone figure out what may be the problem? A virus (which I doubt because I did a scan)? The high and random CPU and GPU usage on my PC? Do I overclock it too much? Do I use my computer too much? Is my hardware being destroyed? I don't know.

Here are my general PC Specs:
GPU: NVIDIA GeForce GTX 460
CPU: Intel(R) Core(TM)2 Duo CPU E6850 @ 3.00GHz
RAM: 8 GB
OS: Windows 10 64-bit

P.S. I use MSI Afterburner to overclock my GTX 460 to 2200 Mhz memory clock and 870 mhz Core clock and also don't use it that often unless I have trouble running games.

I had done this in another section however it didn't get many solutions, I defragged it using defraggler and it helped actually make my FPS back to normal, then after a day it went back to FPS drops. Please help
 
Solution
Start by cleaning your system from all dust and monitor your temps.

An overheated CPU/GPU will clock down to avoid hitting its thermal threshold, such clock down will inevitably produce very low fps so lets make sure first that's not the problem.
