PC Underperforms and crashes.

Specs: Windows 10 Pro, 8GB 1600MHz DDR3
My system has started to loose its stability in the last couple of days. GTA V is under performing and so is battlefield 1. Both do roughly 60 to 80 fps in both with gta v even stepping down to lower 30s in night rainy scenes in the wilderness.
Also when gaming gta v lasts about 2 to 4 hours and the system restarts. I fear the psu is the problem. I don't know yet.
I ran AIDA 64 and the system barely lasted a few minutes with a stress test on the GPU and CPU simultaneously.
Below are the specs of my system.
CPU - i7 4790K
RAM - 8GB 1600MHz DDR3 Kingston
PSU - 600W Seasonic Eco 600
Storage - SSD Samsung 850 Evo 250GB
WD Blue 7200RPM 1TB x2
Case - Cooler Master Scout II
Graphics Card - MSI Nvidia Geforce GTX 1080 Founders Edition

CPU stock or OC? What clock speed?
I have some doubts about the power supply with its two 12V rails (2x24A), that would be 576Watts alone which does not make sense for a 600Watt power supply so it may not be true ratings. I would much prefer a single high amperage 12volt rail and real honest ratings.
What are your temperatures (idle, gaming, stress testing)?
How long do you have this system? Has it ever worked well? Have you made any changes recently (OC, RAM, software, etc.)?
Is that a single stick of memory @8GB or is that a pair of sticks (2x4GB)?
What is your motherboard? Do you have the latest BIOS (sometimes required for the Devils Canyon CPU's depending on the manufacture date or version of the MB)?
Are your drivers all up to date (from component mfg's sites)?

You have to be a little bit crazy to keep you from going insane.

Dear Fingers,
The CPU is stock and is always turboed up to its max capacity of 4.00GHz(P;ease note that this is a non k system).
The temperatures are as follows
CPU GPU
Idle ~42 ~40
Gaming Varies Varies (GPU within 80 Degrees)
Stress Testing (CPU and GPU Alone) 87 ~60 (AIDA 64 and Prime 95)
Stress Testing (Simultaneously) 63 74
All temperatures are in degrees Celsius.
The different components are different ages.
The CPU, RAM, and one Hard Drive are now three years old.
The GPU is barely one year old.
The Motherboard, Power Supply, and Case are two years old.
It used to work well until a few months ago when an incident happened-:
A squirrel had made a nest inside my computer.(Yes the animal)! Then once I removed it I noticed that some of the wires were exposed. probably the squirrel had used some wires to build it's nest.
Then I taped them with insulating tape and ran the system.
However then. I stopped running it the following day as I had my GCSEs to study for and my mother was forcing me to stop gaming for a while. Then I left it there for three months. Once I powered it back on it didnt work well. shut down every once in a while.
This issue was solved here https://www.computing.net/answers/h...
Now I noticed that ever since I start playing GTA V the system is unstable.
I always suspected that the PSU wasn't enough as the graphs were suggesting. (I believe it would be good for you to see it. But please suggest a way for me to share it.)
Not a lot of changes have been made recently.
This is a single stick of RAM
Asus z97 Pro Gamer
No I dont have the latest bios I have version 2102
Yes all drivers are up-to date.
Thank you for your effort fingers, I highly value it.

Lets see if this will give us a clue to what is happening.

Please download Farbar Recovery Scan Tool and save it onto your Desktop. If your default download location is not your Desktop, drag it out of it's location onto the Desktop.

If we have to run Farbar more than once, refer this SS.

Note: You need to run the version compatible with your system. If you are not sure which version applies to your system download both of them and try to run them. Only one of them will run on your system, that will be the right version.
Double-click to run it. When the tool opens click Yes to disclaimer.
Press Scan button.
It will make a log (FRST.txt) on the Desktop.
The first time the tool is run, it makes also another log (Addition.txt)
The logs are large, upload them using this. No account/registration needed. Give us the links please.

Follow recommendations in #3 above.

In the mean time I will mention a couple of things.
A matching pair of RAM sticks are much better than a single stick because you can take advantage of the dual channel mode on the memory. This will not be your problem here but a recommendation for improving performance in the future once this is solved.
If any of the exposed wires can easily be changed out (SATA cables, etc) you should do it soon. If many of them are from the power supply then here is just another reason to replace the power supply. Corsair power supplies are well recommended here.
You noted that the CPU is a 4790K and the MB is a Z97 which are together overclockable so I do not know why you say the system is not a K system. There is no reason to OC unless you want to but I had to ask so we can rule out the OC being core of the instability. If it was OC'd then hard details would have been needed or a reset to default needed to rule it out first.
Being that it ran stable for at least months should rule out the BIOS as being prior to the release of the CPU (this does happen with early versions of the MB's with original BIOS').
In relation to the nest, I would wipe down the MB and other boards (GPU, etc.) with rubbing alcohol to remove and substance that might conduct electricity between higher and lover voltage portions of the boards.
