Also have a master cooler 212 evo.

Had this computer for about 1 year (starting from July 2013) and had a problem where when I am playing games my computer would stutter (minor freezes like half a second), I also want to note that this problem occurred at the start of using this computer. Eventually, my computer would stutter so much, I had to restart my computer. After I bought an after market cooler (Master Cooler 212 Evo.) for my cpu, the problem minimizes to certain games (I can play games like League of Legends normally but not games like Counter Strike Global Offense or Battlefield 4, which are games that need a good computer which my computer can handle). So I was curious to see if it was the dust that was causing the problem, so I used compressed air to blow the dust away and now my computer starts to stutter after booting up! I had used compressed air before on my computer to clean dust away and this would not happen. I desperately need help now!
Typing this in safe mode.

Things I tried:
-To further note about the stuttering problem, I sometimes get this problem which can be seen in this screenshot, http://imgur.com/3ybSeM3
- Uninstalled my gfx card by going into safe mode then used a software to uninstall it. Rebooted normally and downloaded and installed 337.88 driver for my gfx but still not worked. (was 332.21 before).
-I also sent my gfx card back to EVGA for a new one in November 2013 but I still had the suttering problem

 
Solution
Those temps look fine, especially for a stress test. Likely they are 50 cpu and 70 GPU under the stress of a normal game.

Hopefully something just wasn't seated correctly and it'll work for you now.
What are your temps under load for the CPU and GPU?

Have you verified everything(components and connectors) is seated well in the motherboard? Issues getting worse when you had the side panel off using compressed air would lead me to believe something is loose. Also while you have the video card and ram out clean the slots with the compressed air.
 
Thermal or a power issue but most likely thermal, have you physically cleaned your system at all in the year you had it if it were regular use? Also check your temps and look around for any bloat ware or spy ware that could be running while you are gaming.

I have replaced the thermal paste couple weeks ago, applying to about a size of a pea. I cannot test out gpu or cpu temperatures at the moment since I am not able to boot up to my computer normally but I will try to as soon as the opportunity arises.
@bccourpt I cleaned out the slots with compressed air and checked every component is properly mounted correctly
Also, ran a malware scan but no viruses to be found.
 
Did you do any work on the graphics card or just the cpu, if it were the cpu and temps are normal then that isn't the issue. Also inspect the card for anything broken or missing on the side facing the cpu, it is very easy to break off a resistor or two when careless.

My computer does not turn on anymore, after inspecting my computer, I look inside my PSU and saw some white ooze. It looks like some of the components melted off. Here's a picture of it, http://imgur.com/jOPYkG3
I think it was part of strap that was used to hold the stuff inside the psu. Do I ask for a refund or should I just clean it out?
 
It could be your power supply, but there isn't anything to clean and if you open it up you will void the warranty. I was thinking power supply earlier, but it's a good model, so it would be rare. Nothing is coming on now? Do you have another power supply to test with?

Wait, after switching the PSI-E plugs, I can turn it on now. Testing to see it can run normally. Thanks for being here though!
