I'm wondering if my CPU is ruined.

About 2 and a half years ago I built my first computer (Yes, I'm pretty inexperienced). The specifications were as follows:

Intel Core i7-3770K
MSI GeForce GTX 660ti
ASRock Z77 Extreme 4
Antec 750w ATX12V / EPS12V
Corsair Vengeance 16GB DDR3-1600
Windows 7 Home Premium 64 bit

I use this computer to play games such as counter strike and battlefield 3 and 4 on almost a daily basis, and for frequent video and photo editing.

After about 4 months with my new computer I began to have hardware issues - My computer wouldn't turn back on for about half an hour after I'd been using it for a good amount of time. After a ton of calls and troubleshooting, it was determined that the problem was my power supply unit. So I got this one:

Antec 750w ATX 12V v2.32
^Basically the same PSU I had before, but with modular cables.

Replacing the PSU, seemed to fix the problem, but my PC's performance seemed horrible, especially when playing games. Since then my PC has been running most of my games (even counter strike) under 60 frames per second. Metro last light runs at 10 FPS on the lowest graphical settings.

About 5 months ago, I got this graphics card:

EVGA GeForce GTX 760

I noticed absolutely no performance increase when using this card, and decided to troubleshoot the problem by calling EVGA. They were unable to help with my problem.

One more detail I should mention is that I recently adjusted all settings in the Nvidia control panel to get maximum performance. For some weird reason when I first did this, I was finally getting great frames on high graphical settings (I always play on low settings and get around 40 FPS on most games) on battlefield 3 and 4. The next day, everything was back to normal and running terribly. I checked the Nvidia control panel to make sure that my settings were as I'd left them, and they were.

Here's where you get to call me a total noob...

I recently had the idea that my processor was the problem, so I took the processor out of the computer that I built for my dad (Intel Core i5-3570K), and tried putting it in my PC. I didn't remove the thermal paste from before and did not apply more paste. The computer shut down as it tried to start windows. When I turned it on again, it shut down faster than it did before. I decided to troubleshoot the problem and found out that you must re-apply thermal paste when you take off the heatsink.

I thought back on what I'd done when troubleshooting problems about 2 years ago and remember taking my heatsink off of my processor, and putting it back on without removing the thermal paste and re-applying more.

I'm wondering if my processor is ruined and if I messed up my dad's processor. They both look completely fine, but what the heck do I know?

Right now I'm unable to use my PC and am waiting for thermal paste.

Thanks for your help in advance!
 
Solution
If a cpu chip gets too hot, it will shut off to protect itself.
Both cpu's are likely ok.

One possibility is that you may have damaged the pins on which the cpu is mounted.
They are very delicate. If a pin is bent, it will alter whatever that pin controls.
Carefully remove your cpu and look at the pins. You may need a magnifying glass.They should look absolutely uniform. It is devilishly difficult to fix damaged pins and they are not covered under warranty.

Solution
Your best bet is to seat your CPU back into the socket, apply thermal paste and replace your heatsink and see if your system fires up. You will have to do the same thing for your Dad's PC as well to try to get it to work. Your parts are real nice, in terms of those games performance, many things could be causing those issues like things on the companies side or you having to adjust more settings to get optimal play.

Sounds like a thermal issue. I would suggest that you clean off the thermal paste and reapply and make sure the heatsinks are mounted correctly. If the CPU gets hot it'll throttle to slow down, or it may shut down completely. What kind of temps are (where) you seeing?
 
I agree with geo likely the CPUs are okay but the motherboard pins nay be damaged or perhaps you didn't put the CPU in the correct position. Also be sure the heat sink is properly install or the system would shut down. After you follow geo's instructions and confirm the pins are okay. If any are bent the motherboard mfr's will reject any RMA request because of physical damage. Time to buy a new one.

If the Pins are okay you can take a Q-Tip with some (not too much) rubbing alcohol on it and gently remove the old thermal grease from the CPU and the heat sink. Then be sure both surfaces are clean and dry then you can apply fresh thermal grease. Some like the pea way where you put a small ball of thermal grease on the CPU. Then when you firmly press the heat sink on it will spread out. This doesn't always work for me so I just spread a very thin coat I can see thru over the top of the CPU. Be sure the connectors of the heat since are properly attached to the motherboard. Good luck!

Thanks everyone for your help. I just made sure that the CPU socket pins on my motherboard are fine, and they are. I also prepared my CPU and heat sink for the thermal paste I ordered which should arrive in a couple days. Don't worry, I'll lightly clean it again right before I apply the paste.
Thanks again!
