I am using a Lenovo Z50-75, 64 bit AMD Processor A10-7300 Radeon. Since 1-29-18 the computer randomly shuts off while in use, and restarts. This has happened sporadically with no rhyme nor reason, at various times during the day. Today it shut off and restarted immediately after I turned on the computer.
I was travelling from the end of December to January 22, 2018, so my computer was off during that period of time.
The event log indicates a Critical event occurring. A couple of times it read Kernal 41 Task 6 event ID. On another occasion it said Controller Error Device HardDisk2 DR8.
I tried to do a system restore to January 22, 2018, but I receive an error message about my anti-virus protection, which is only Microsoft Defender. I disabled the antivirus and I was still unable to do a system restore.
I tried to uninstall the January Microsoft updates and there is one I wasn't able to. I don't believe the computer is overheating, and I tried using the laptop without the power pack, and I had no problems.
I really don't want to do a complete restart so thought I'd see what your thoughts are first. Thank you. Pam
