MSI GT70 2QD Dominator (Bought on 29/06/2014) PSU problem

[truenostradamu14f902cc]

Hello and good morning everyone Nostradamus here, I have had a msi GT70 2QD Dominator since the last 7 and half years (bought on 29/06/2014)
Specifications:
OS: Windows 8.1 pro x64 bits
CPU: Intel(R) Core(TM) i7-4710 MQ CPU @ 2.50GHz 2.50 GHz
16.0 Gb RAM
1TB HDD and 180 Gb SSD
GPU: GeForce® GTX 970M

I will leave also this link with the complete specifications but since this one is a new version of mine I don't know exactly if there are huge differences between them:

My problem is that since the last 6 months I've been having serious issues with the PSU because whenever I am playing games wich shouldn't be high demanding such as Payday-2, Battelfield 4 or COD BO3 there is an unknown time where the PC just completely dies and switches off, sometimes it restarts itself and other it just stays off, well this just doesn't end here, since a few of the times I power it back, checking the power charger, overheating issues (which can't be because this monster has been always on a specific cooling bracket with an extra large fan to aid internal cooling of the notebook) wires and all I get my steelseries drivers gone and I have to reinstall it manually which it's kind of frustrating, I also get an issue with the fan were it automatically turns on to 4500/4700 RPM as it turns on the PC (It is usually on 1900 RPM or up to 2500-2700 RPM or little higher playing videogames) and there is no way to turn the RPMs down (yes, I tried Speedfan software and 1000 thousand things to change the speed) the only thing that works is leaving the PC without charge X time and then plug it back the charger, that way i recovered my steelseries drivers, my normal RPMs of the fan and one time also my GPU because it went absolutely missing even in device manager.

With this said, my question because I know the PSU is sticked very inside the laptop under the GPU and CPU is:
Is there any way to get the battery and thermal paste replaced without already being under warranty of the product, and if not could someone who has had this model or similar tell me their experience and solution regarding this PSU problem?
I leave the link of the video I saw of a guy who changed the battery to the GT 72 model, I do not know if the interior is exactly the same but I imagine it will work, my problem is that I do not know if it is worth changing the battery because this guy stated that even changing the new battery did not work 100% PC and was considering buying a new computer.

Thanks everyone for spending time reading this, I hope that someone can read this and help me, and solve the problem to someone else if we find the solution, have a nice day to all of you.

Sincerely, Nostradamus.

Could be battery issue, or that the hardware is shutting down due to temps.
Is the battery status indicator blinking amber?
Might have to contact the local service point to have your laptop checked.

Thanks for your reply Hethdra_0328,

In the end after performing several stress tests connected to the current with the battery, connected to the current without battery and only with the battery I have come to the conclusion that the problem is very likely to be the AC adapter and that does not work as it should, I tried it in several different outlets these tests and the conclusion was the same. In any test performed where the laptop was connected to the current after a while (when the laptop starts to ask for more power) it turns off, while using only the battery without charging I could play to the maximum possible until the laptop was discharged, hence I have chosen a power adapter of the same power, amperage and voltage input and output compatible with my msi model to see if with that I definitely recover my laptop, because neither the graphics, nor the ram, nor the processor or the motherboard are affected, thanks for your time and advice it is nice to have people help you out here on the internet and by the way, I also read the manual of the laptop regarding the flashing LED of the battery and it does not happen to me, so I ruled out that the battery itself wasn't the defective component and that is why I concluded after the tests that the power adapter is responsible for my headaches, not in vain you will never stop learning.

Sincerely, Nostradamus.

No problem.
You could try to get a new adapter from the local service point and see if it works.

So I got this: https://www.amazon.es/gp/product/B08YRR1QFY?ref=ppx_pt2_dt_b_prod_image
and came today to make new tests with the new AC Adapter, and there was no overheating either on the CPU or GPU yet it automatically switched off after a few minutes, any thoughts?
Kind of driving me crazy this.

I personally wouldn't buy adapters off the internet.
Can't be sure if they're actually from MSI.
