Hi

CPU G3258 Intel Pentium
Mobo Asus Z87 A
GPU GTX 980Ti
CPU cooler Coolermaster 240M
Storage Intel, Samsung SSDs. 1 WD 4TB mechanical, 2 Seagate 4TB mechanical

A little background. The Z87 A has thermal compound on and around the CPU socket. The sockets has pins bent, but was fixed.
I was rocking at 4.3 Ghz Overclock G3258 for around maybe 2 months. One day it started having experiencing restart looping. Where when I click power it tries to power up, fans turn for 2 secs, and powers off, again, and again. I cleared the CMOS. trouble stops, The next day, thing happen again, I clear the CMOS trouble continues. I takes off my GPU. Trouble stops. I put on GPU Trouble stopped.
Now the computer experience restart loops but maybe 2 or 3 attempts with hard power off it boots into windows 7, it will freeze within five minutes browsing the web (tomshardware, youtube, twitch, etc). I also cannot use google as it will say something like your clock is slow. (This maybe a unrelated virus problem).
Now I got a BSOD tech readout.

TLDR: I need experts to read this:
xxxSTOP: 0X0000007E(0XFFFFFFFF0000005,0XFFFFF800025BBC10,0XFFFFF880009A8C18,0XFFFFF880009A8470)

and tell me if it tells us anything and if so which part(s) of my computer is broken?

 
Solution
Well the error number can be generated by a few things.
If you get to windows though then it randomly crashes the error code of 0X0000007E

More than often point to a system thread exception.
What it means in English is the thread was not executed because the cpu was using or doing something at the time.
So it timed out.

It usually happens when a driver for example wants to execute a task via your cpu.
The main causes of it can happen due to a cpu being damaged. Or it can happen when the bios of the motherboard does not fully support the cpu fitted in question.

To fix it sometimes you are required to update you bios firmware to resolve your problem.
Other causes can be down to how much you overclock your cpu and how much voltage you...

The PSU is a Corsair AX860.
The cpu as a g3258 is because I lost a bet. I had i7 4770k before.

AS for the full bsod tech, it's kind of difficult to install software when the computer freezes during installation. The bsod had nothing else anyway except the standard bsod happened please restart. Nothing like it was caused by blah.sys or anything. The only usable thing was that xxxSTop thing, it that doesn't tell you anything I guess it the bsod told us nothing.

The main causes of it can happen due to a cpu being damaged. Or it can happen when the bios of the motherboard does not fully support the cpu fitted in question.

To fix it sometimes you are required to update you bios firmware to resolve your problem.
Other causes can be down to how much you overclock your cpu and how much voltage you have applied to the Vcore setting in the bios.

Things to know about overclocking cpu`s are because of a voltage increase and a core overclock it weakens the integrated circuit path ways over time. The rate of decay is speed-ed up.
All integrated pathways weaken through time and age, even if you don`t overclock a cpu for example.


Here is the bad point about overclocking the weaker the circuit path way gets the more it leaks current, or migrates the signal to adjacent integrated path ways of the cpu die.

What tends to happen then is you have to reduce the overclock like you had to do on the cpu. but keep the voltage at a slightly higher level on the Vcore in some cases to keep the cpu stable.

Any slight power fluctuation and the cpu is more prone to producing errors while consuming power.
That is one of the points stated that can happen to a cpu if to start with the integrated data pathways are not well formed in a batch of silicone that they produce the cpu die on.

All you can do is take the overclock off to try to prevent the errors if the cpu is impaired.
Or if your lucky you may find the cause is as simple as patching the motherboard with the latest bios firmware.
If there is a newer one than the one you currently have running on your motherboard.

Because it has got worse over a time scale I would lean towards the cpu at fault.
The bad posting would suggest the cpu is not being detected.
As well as the random crashing within windows at random times.
Mostly executing something to run on the cpu.

Anyway give the suggestions a try, if you have tried everything else.
