Computer suddenly became extremely slow

I bought my computer about 6 months ago with hopes in having a gaming computer that would last me a very long time. A long time meaning 3-5 years. I have currently spent 2.3k dollars on such computer, and up until now have gotten my monies worth. I used to be able to run mass effect, Starcraft 2, and League of Legends at full graphics without ANY lag whatsoever, but as of right now I can't run Mass effect, I can't run Starcraft 2 when fights with large masses of creatures occur, and I can't run League of Legends when team fights of 9-10 people occur. My specs are listed below:

Intel(R) Core(TM) i7-4770K CPU @ 3.50GHz (8 cores BUT ONLY FOUR ARE SHOWN BEING USED).
NVIDIA GeForce GTX 770.
8 GB of RAM.

I have already checked for component failures using multiple programs, and have already cleared my computer of all MALWARE.

Please, please, PLEASE help as I am a extremely avid gamer and love doing it and helping me out would mean the world.

If either reaches 90 degrees C at full load, there's a problem. Ideally they'd be well below that, especially the CPU, but it doesn't hit performance until the 90s. Coolers clogged with dust is one possible cause, and clearing out the dust (eg. with compressed air) would fix that.

Sorry, I'm new to this computing and so I don't have a hole lot of knowledge when it comes to this subject. As for the hardware temperatures, what would be an abnormal amount, and how would I fix such a problem?
