Hi all,

hoping to get some of your knowledge on my situation.
Have an MSI GT72 2QD gaming laptop - Windows 10 - 3 years old.

Never have had an issue with random shut downs until recently - only shuts down when gaming -usually within an hour.

Temperatures on 2 different programs do not go above 70C for both GPU and CPU.

90% of the time it is a instant computer shutdown without a restart.
10% of the time the computer instant shuts down but then restarts itself.
Sometimes the desktop icons are shuffled about.

I've tried the works:

- event viewer shows nothing of value (in my opinion, but my troubleshooting involves a lot of googling)
- Uninstall latest graphic drivers and install MSI base ones
- Clean laptop out of dust completely
- Checked under heatsinks and all looks OK thermal wise
- Checked MOBO etc. for any marks / burnt smells
- Reset / Reinstall windows
- Unplug battery and run on adapter only
- Battery only without adapter
- Turn on options to stop computer from restarting when there is an issue
- Run TRONSCRIPT
- Defrag
- Antivirus / Malwarebytes etc.

One thing that seemed to help was when I updated the GPU drivers back to the latest version - I played for a full 6+ hours without issue. But this morning when playing it shut down randomly again and I've run out of ideas - I really do not understand how it let me play for 6+ hours yesterday and today 20 minutes into a game it dies.

Any ideas ladies and gents? Could it be a shortcircuit of some kind?

*to add - sometimes the laptop will not turn on unless I unplug the cord in the power supply and plug it back in

** gotten a lot worse over the past 2 days - now will shut down within 5 minutes of gaming. When trying to turn it back on, the laptop will shut down again 2 or 3 seconds after I press the power on button...sometimes have to press the power on button 3 times before the laptop actually boots and I can log in.

*** seems to only happen with more intense games. Was playing Spelunky without restart...could it be the GPU?

It could possibly be a short circuit. However, you said it only does it when it is gaming correct? Have you Overclocked your CPU? I had the same issue with my desktop and couldn't figure out what was going on. Come to find out the AutoOC setting had became enabled and was causing my system to become unstable.

Thanks for the tip - CPU and GPU have not been overclocked.

Currently it seems when the shutdown happens the power supply (charger) light goes off and I cannot turn the computer back on until i've unplugged the thick connector from the brick and plugged it back in.

Are you able to run the laptop with just the battery installed? If so do you experience these shut downs?

Did you get a solution for this issue? I have the same make and model of OP and my GT72 has started to do the exact same thing.

Mine was only occuring when on mains power. My device has been in for motherboard repair since jul 18 and still no confirmation of getting it back. I've done a lot of research and believe it could be a faulty power I/C on the board. The thing is, the power brick has a safety feature that's cuts power when it senses a surge which it why your power drops instantly and can't be switched on until you pull the power brick from the mains (look at the power brick light next time it happens, the light will be off). Once I've got mine back with a solution I'll post again.

I've believe the fault is caused by the GPU drawing power whilst gaming. To much power is draw because of the fault and the power brick safety feature cuts in and kills the power. This feature will bypass the battery to prevent damage to board components.

old boards tend to lose some of their electric circuits even in slight heats, because of so much resizing cycles by going through high and low temps. main solution to this is to reball the main chips which are soldered to the mainboard, when your laptop is going through some high temps and when the high temps causes some reshapes in the board some chips get disconnected and the system shutdowns.

Yeah. Board engineers have tried this. I got my laptop back and it lasted less than a week and has now gone back again for repair. I dont think reballing is the solution here. I've ask for a full repair report when I get it back but I've had quite a bad experience, I'm not optermistic.

Not yet, I've got my into an independent repair shop and am awaiting an update. Get the fault registered with MSI because if your in the UK you might be entitled to repair under Consumer Right legislation. You'll need to register the fault though ASAP.
