Unexpected Shutdown

Hi

Please see response to your questions below

• Did you make any changes on the computer prior to this issue?
  

No changes other than about a month ago reinstalling W10.

• What troubleshooting steps have you done so far?

Other than checking updates have successfully installed, none as not sure approach to take.

• What was the exact error code/message you have received?

No error code or message received. On the first occasion I was looking at outlook and without any warning the PC shutdown. It was almost as if it was a desktop (it is a laptop) and the power stopped. The laptop was plugged into the mains and in addition
the battery had a full a full charge.

On restarting the laptop no error message came up and I only noted a small difference in boot up, that for a short period a blue screen was displayed (not normally seen on boot up) and then the start screen appeared for me to log in.

As mentioned previously the only reference to this is from the log which in the summary states that there was an unexpected shutdown.

 

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?
