PROBLEM: NVIDIA GTX 760 does not run games well at all anymore, fps drops a few minutes into the game

Hello Tom's Hardware,

I've seen this forum in the past and it has helped me out a lot, and hopefully, it can help me out again. Here's my problem:

I've had my NVIDIA GTX 760 graphis card installed on my Windows 7 desktop computer since last Christmas (of 2013). I installed it with no issues, and ran games (the reason I bought it) at an amazing fps rate, no failures, great great product.

Fast forward to this year. After a Christmas trip (from Christmas to January 5th), I arrive back to my computer. For the first week and a half maybe it works as normal (play games fine and such), however, I stopped playing until perhaps last week or something.

This is when I encountered the problem: for perhaps the first few minutes of playing the game, it works fine, maybe a bit laggier than it should be, but overall fine. Then, a bit in (not necessarily during me playing - this has happened while I was waiting at the main menu), the FPS drops super low that it is almost impossible to play the game. I've tried on games that can run well on even integrated low-quality graphics card, and still run better than what I'm encountering. It usually freezes, then continues at low fps, then freezes again.

It eventually becomes impossible to play the game properly, so I force quit it (since it keeps freezing up). When I quit, my computer itself is super laggy and I can hardly do anything for the next 5 minutes or so, until it sorts itself out. From time to time (very rarely), even when using a normal program (Firefox, Word), it might also do this weird laggy thing.

I thought perhaps Windows 7 was going out of date, so I updated all the way to Windows 8.1, yet it still happens (in fact, a bit better, since it doesn't freeze, but still so laggy).

Hopefully somebody can assist me in this problem. Thanks!

SIDE NOTE: I couldn't find anything anywhere else (everything else was game-specific problems). On some forum I read it could possibly be the temp, however, with my fans and the fact that nothing even close to this has happened before, I'd like to believe it isn't.

Specs:
Intel i5-3570K CPU @ 3.40GHz
16gb RAM 1333MHz
NVIDIA GTX 760
3TB HD (won't really be specific since I don't think that is the problem)

Thanks again!


EDIT: I downloaded a hardware monitor (it is actually lagging right now), and these are the results:

CPU: 100C degrees
GPU: 33C degrees
TOSHIBA Harddrive: 36C degrees

I have a feeling that the CPU might be a bit hot...

I just posted my heat things, and I believe the CPU is getting too hot (it was just running at 110C). I looked online and apparently that is a lot...

I am running Avast! and I do have the latest driver.

Do I have to buy that or should that be on the CPU or something? Any brands (if I have to buy) that is recommended for my CPU?

This is a really good thermal paste and I've used it several times. Use rubbing alcohol to remove the old paste from the heatsink and CPU. Apply a little of the new paste to the CPU and re-install the heatsink and fan. You can look up videos on YouTube for a visual on how much paste is appropriate.
