    I suggest that you change the thermal paste and clean the fans:

    Update 2: Now my laptop is working as expected, no more overheating and auto shutdowns.

    The main reason behind all that was... Acer Care Center, after I uninstalled that I haven't faced any auto shutdowns and/or overheating issues.
    The system BIOS information is stored in Acer Care Center too and I think it's interfering with the system firmware somehow. Device Manager shows Firmware version 1.19 (which was the old one) but Acer Care Center shows 1.28.
    System restarts after 3 BIOS beeps which means RAM error but my RAM is working as expected (tested on other device) so its most likely the Care Center application creating the problem, now I uninstalled it and Laptop is running perfectly as new. :)

    Try updating the firmware driver through windows update.

    Already done that and it gave me 1.19. As of now I'm running with no problems so I guess that's perfect.

    Just right click on the firmware driver 1.19, click update driver and click on search automatically for the driver, it will automatically get the Acer system firmware 1.28 driver from Microsoft database.
