Laptop overheating / shuts off

[Harry1337]

My laptop shuts off and restarts randomly, but the temps are fine..
Idle: 39-40
Gaming: 45-60
It does NOT shut off when on battery (NO AC Adapter)


What i tried:

Updated BIOS
Updated Drivers
re-installed OS
Placed new thermal paste
re-seated both RAM's


Any ideas? The problem started one month ago, still can't find a solution.

If it does NOT shut off when on battery on full load but shuts off on AC Adapter it would make me think the AC adaptor cannot supply enough power OR is shorting things out from time to time

Well, I tried A different AC adapter and still have the problem. Is it possible to be a MoBo problem?

Yes that is also possible but not as common, Do you have warranty? If you don't I would take it to one of those "Don't Pay unless we fix it" computer shops as laptops are more complicated to troubleshoot
