Acer Predator Helios 300 PH315-51-50PN randomly shutting off

I wonder if any one can give me some help and advice. I know my way around a computer, have fixed many computers & laptops and have built many computers but this laptop has me stumped.

I have a Acer Predator Helios 300 PH315-51-50PN. Its a gaming laptop that I brought for my son a couple of years ago to use when in hospital. My son has complex medical conditions and spends alot of time in and out of hospital.

He relies on this laptop when in hospital, to do his school work and for playing games and watching videos.

A few months ago we started having problems with the laptop. It started getting quiet hot (80c) and kept randomly turning off then would not turn on at all.

I opened up laptop cleaned fans and re thermal pasted CPU and GPU and replaced power supply and this fixed problem for a while and was able to get laptop to turn on and work fine.

Recently laptop has started to go wrong again. It randomly just dies and when you try to switch it on again it appears mother board and bios has reset as time is wrong and it blue screens.

In order to get computer to boot again I have to go in to bios and adjust harddrive Sata mode settings as when laptop dies and mother board re sets it adjusts hard drive Sata mode to wrong setting so won't boot.

I thought at first maybe it was over heating again although laptop did not feel hot when it would turn off.

Anyway just incase I opened up laptop again, took fans out and replace with new fans as noticed one had a broken fan blade, I re thermal pasted CPU and GPU again and even replaced all thermal pads.

Put laptop back together and it made no difference laptop will work for a while then will randomly shut off and motherboard/ Bios resets.

I have also tried re seating ram sticks and even replaced ram sticks and replaced SSD.

I have even done a fresh install of windows 10 and it's still happening.

I monitored temperatures and each time it randomly shut off temperature never went over 70c. So don't think it's overheating.

I then thought maybe it's the cmos battery so replaced the cmos battery and again this made no difference.

I then replaced the power supply again and main laptop battery just to make sure.

New battery has made thing even worse it now shuts off with in seconds of booting.

I'm at a loss as to what else it could be

All drivers are up to date, only thing I haven't tried yet is updating Bios as know this can be risky and was leaving this as a last resort. Could it be a problem with Bios Is it worth doing a bios update

Only other thing that might help is that when I reboot laptop and go to event viewer it shows a critical error.

Event ID 41.

The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed or lost power unexpectedly.

I've tried to have a look at memory dump to try and see if I can work out problem, but it turns off so quick it doesn't have time to create a memory dump so there is no memory dumps being created

Can any one give me advice or help on what else I could try to fix laptop.

I really want to fix it as can't afford to buy another right now and my son is devastated.

Thanks in advance

    Unplug the power cable and turn off the unit and press and hold the power button for 30 seconds. See whether u have the same issue again if yes, with the help of any local tech remove the ram from the laptop and wait for 5 minutes and put the RAM back in.
