Windows 10: PC shutdown whit normal use

I have a msi mag codex 5 11td-1430eu. When I use it as usual watching videos on HBO, Netflix, youtube by chrome, or while I'm writing this, suddenly screens shutdown but PC continue working fans still rotating. But, if I play a strtong game that requires more energy, I don't have this problem.I check drivers, energy problems and corrupt files, but it continue with the same problem. There is not errors showed blue screen or event logs. Any idea?Thanks for your help

My pc takes for ever to shut down when i restart

Suggest cleaning up your startup list .There may be many services / Apps you can remove on startup which is not needed on boot or during shutdown.
Before you shutdown the Pc check what is running in Task Manager as a program or service in not killing the process on shutdown

Would suggest cleaning up running apps and services -Autoruns, StartupMonitor,HighjackThis,
Malware Scan - Malwarebytes,ADWcleaner, Combofix

 

PC is Suffering Unexpected Shutdowns

Most important detail to me would be whether these shutdowns are sudden, in which case it's likely a short or PSU issue (capacitor aging maybe?) or graceful windows style shutdowns, which suggests software interference.

It could also be overheating components if it's a sudden shutdown. What are your thermals like?

 

PC is Suffering Unexpected Shutdowns

So its been almost two weeks since i last posted and since my PC has shutdown unexpectedly... My original plan was to play around with the RAM to see if that was the issue but after a few days of no shutdowns i figured i would see if the CMOS clear and repairing the corrupt OS had fixed the issue. As i already said its been almost 2 weeks since i first made theses changes and i was fairly certain it had fixed the issue...Unfortunately my PC did shutdown unexpectedly today while i was at work. It seems pretty ridiculous to me that the PC could be on for almost 2 weeks straight and have no issues then just randomly shutdown...I ran the SFC scan to make sure nothing had gone wrong with the OS and it reported no issues. My next step i guess would be to try and eliminate the RAM as the issue but honestly i find i very hard to believe that's the issue after the PC was on for 2 weeks. Surely if this was a hardware issue i would have more regular shutdowns...or at least shutdown while im actually using the PC...What do you guys think?
