My Laptop is shuting down randomly

I am having an issue with my laptop. first it started shuting down like twice a week, it would just shut off. from nothing
This occurs even if I have my charger plugged in when im just going with the battery and when im just using the charger without the battery. I alsow tried diffent outlets. It happens when im just surfing and doing basically nothing.

Now it has come to a point when it shuts down 8 times in one houre i cant use the computer anymore. I thought i would try to reinstall windows but during the install (not even in windows) it shuts down. Im trying to se a pattern but i cant, i think its weird that it started just one time and then it got more and more intense.
sometimes i can barely start it up before it shuts down and sometimes it takes a while.

I dont think its my GPU or CPU but im not sure. I should add that i just got it back replacing the whole motherbord because of an issue with my sound. and i did not have this problem before.

What the hell is this?

 

You should check temperature. Download HWinfo64 and check max temps after 5-10 minutes.

Perhaps you need to clean the dust or change thermal paste.

 

seems ok. max temp on CPU 57C and GPU 54C

 

Temps look good, considering that you didn't have the problem before the motherboard was replaced it could very well have to do with that.

Try a power drain (unplug AC adapter and battery, press and hold the power button for 30-45 seconds, reconnect both and give it a go)

Reset your BIOS defaults (F2 at startup to get to the BIOS and then F9 to load defaults, F10 to save changes and exit)

Please post specs and revision whenever you have a chance.

Start logging with Hwinfo64. After shutdown send here txt file and screenshots of sensor window HWinfo

 

I turned it back in. I guess they have to replace the motherboard again. it sucks and i probably will be about 3 weeks before i get it back again. this is the second time in like 2 month i turned it in. been in for repair total for 6 weeks with this.. disappointed

 

Sorry to hear that, if the issue continues after that 2nd depot let us know through an e-mail [email protected].
