PLS Help.. Suddenly getting low fps on Good PC

[CaptainWaffles]

Disclaimer: I have already tried troubleshooting my problem by going through many internet forums which is why I am writing here. I tried cleaning my registry, defragging my hard drive, running an antivirus check(Avast and WIndows Defender), and reinstalling nvidia graphics card drivers.

 

Suddenly, I believe after I installed a windows 10 update and updated nvidia graphics card drivers about two weeks ago, my PC got really slow (although not sure those are the cause for my issue). For example, I used to get around 280 fps on csgo but now i get 140 fps that sometimes drops to 60 and my fps in league is now around 80 when I used to get over 200 fps on all the same settings. This is more problematic for games like Battlefield 1 where I used to get around 80 on all max settings but not i am getting around 30-40. 

 

My PC specs are: 

Geforce GTX  980ti (not overclocked)

i7-4790k (not overclocked)

12GB Ram 

MSI Z97S SLI Krait Edition

CoolerMaster G650M PSU

Windows 10

 

I'm really not sure what else I can do about my issue except trying a clean install of windows. Note that my temperatures for my 980ti should be fine, they are always under 80 degrees celsius due to the fan curve I set on MSI afterburner. Also my CPU temps are under 60 degrees Celsius so I dont think the problem is my temps.

Any suggestions are welcome.

 

TL:DR suddenly getting low fps on good pc after trying fixes on the internet 

 

Sorry if my formatting sucks

Have you tried installing the old one that you had before getting these problems?

I havent, where can I find the drivers. The one im looking for is two driver updates before the last one that came out (on 8/13)

Use this:  http://www.guru3d.com/files-details/display-driver-uninstaller-download.html

 

Then here is the driver from 2 releases ago, assuming you are runing WIndows 10 64 bit: http://www.nvidia.com/download/driverResults.aspx/120486/en-us

@TahoeDust posted a link, in general you can find legacy drivers on nvidia's website going back a couple of releases at least.
