Why does my acer swift 3 (2019) shut down by itself

The whole story is as follows: -Bought a perfectly working second hand swift 3 (2019); -My mom spilled water on it and killed it; -We bought a whole new motherboard from Alibaba with an i7 instead of the default i5 and revived it -It started shutting down on its own -Tried everything, my father took it down to the IT repair guy in the technical university he works at -The IT guy found out that the graphics card (i think Nvidia mx-line) that the MB came with was broken and was overheating when looked at under thermal cam, so he disabled it. -The problem subsided for a while but now it continues to overheat even with no background applications and shuts down instantly by itself.

Symptoms are: Overheating over nothing, shuts down (without any procedure just lights out (sometimes it says locking for a split second)) and when it is in this coma state the fans run at maximum speed and i cant turn it on for maybe 30 minutes. Holding down the power shuts it off but when i try to power it back up it does nothing. Its not the screen as i tried the graphics card reset shortcut and it does nothing and when I boot it wallpaper engine boots in safe mode so the laptop shuts down INSTANTLY when it decides to. Its not even that hot too.

Is there a way to disable the self-shutoff when it overheats or is it hardware baked in?

Can anybody help with this? If more information is needed i can provide it

    this is copy-pasted from reddit where i asked this originally and the new MB has an MX150 that i disabled from device manager and uninstalled

    How well was the thermal compound pasted when reassembling with the new motherboard. Both GPU and CPU overheating issues will happen if there isn't a good thermal connection between the chips and the heat pipes. For more detailed help we are going to have to know just which model you have. Your full model number is usually on the same sticker as your serial number, it should look something like SF3xx-xxx-xxxx. Swift 3 by itself leave too many options, even with the 2019 qualifier. It might be Intel based or AMD based…

    An Acer Swift 3 (2019) shutting down randomly could be due to overheating, a failing battery or power supply, or a problem with the hard drive/SSD. Overheating is a common cause, often due to dust buildup in the cooling system or a malfunctioning fan. Other potential issues include failing soldering joints, especially on the GPU, or software problems.
    Here's a more detailed breakdown of possible causes:-

    1. Overheating:
      Dust and Fan Problems:
      Dust buildup in the cooling system can hinder airflow and lead to overheating. A failing fan or one that's not rotating properly can also cause the laptop to overheat.
      Poor Ventilation:
      Using the laptop on a soft surface like a bed can block the vents and cause overheating.
      Old Thermal Paste:
      If the thermal paste between the processor and heatsink is old and dried out, it won't conduct heat effectively, leading to overheating.
    2. Power and Battery Issues:
      Failing Battery:
      A failing battery may not be able to provide enough power, causing the laptop to shut down to prevent damage.
      Power Supply Issues:
      A faulty power adapter or power supply can also cause the laptop to shut down unexpectedly.
    3. Hardware Problems:
      Hard Drive/SSD Failure: A failing hard drive or SSD can cause system instability and shutdowns.
      Soldering Joint Issues: Some laptops, especially those with high-powered GPUs, can experience cracking of soldering joints on the motherboard due to prolonged heat.
    4. Software Issues:
      Driver Problems: Outdated or faulty graphics drivers can cause crashes and shutdowns.
      Software Conflicts: A conflict between different programs or a virus can also lead to unexpected shutdowns.
      Troubleshooting Steps:- Check for Overheating: Ensure the laptop is placed on a hard surface with good airflow, and consider cleaning the vents and fan.
      Monitor Temperatures: Use software like Speccy (free version) to monitor CPU and GPU temperatures and see if they are exceeding safe limits.
      Check Battery Health: Use the battery health tool in Windows to see if the battery is failing.
      Update Drivers: Ensure that all drivers, especially graphics drivers, are up to date.
      Run System Checks: Run a system check to look for hardware problems like hard drive failures.
      Check for Software Conflicts: Identify and troubleshoot any software conflicts that might be causing the shutdowns.

    Start by cleaning the cooling system to ensure the fans, vents, and heat sinks are free of dust and allow proper airflow. Reapply high-quality thermal paste to the CPU to improve heat dissipation. Use a laptop cooling pad to further lower the overall temperature during use. Adjust the CPU and GPU settings to reduce performance and heat generation by enabling power-saving modes
