Aspire Z3-715 Shuts down without warning

Hello,

I have been facing this issue persistently now, where my AIO PC shuts down in the middle of use and without warning. The event viewer indicated an unexpected shutdown but no reason why. Ths has been going on for weeks and happens about two or three times during the day. I read somewhere it could be to do with the CPU temperature spike or something, but don't know what to do about it? Do I need to clean up the fan? I have been using the PC since 2017 without any servicing.

Please advise.
Thanks

    Hi,
    Yes, it could be due to high temperatures, download and install HWmonitor and watch the temperatures, you can also clean the fan and repaste the CPU to reduce the temperatures.

    Let us know what the temperatures are that you are seeing, but when the computer is sitting idle and when it's working hard...

    Might be that the cmos battery is dying...I just took my moms computer (same model) after she passed away. My son was going to toss it out.  After alot of googling I found that to be the problem (even though all the experts said no chance).
    Guess what ? Just replaced the  battery and it boots up and stays booted now. Anyways, hope this works for others as well!

    Cmos battery is meant for keeping up the date and time right.   It is a small coin type of battery responsible for the correct date and time even if you turn off the computer.   If you have any issues with the computer, please let us know.
