Installation fails

AMD Athlon 64. 160GB hard drive.
Manjaro MATE runs OK as live usb, but will not install.
When I click the Install icon the installation starts and continues through keyboard, time zone, partition and so on. After about 30 minutes my machine just switches off without completing the installation.
I have dome a fresh download of the .iso file, and verified.
Also tried KDE.

:+1: Welcome to Manjaro! :+1:

  1. Please read this:

    and press the three dots below your post and press the :pencil2: to give us more information so we can see what’s really going on.
    Now we know the symptom of the disease, but we need some more probing to know where the origin lies… :grin:
  2. An inxi --admin --verbosity=7 --filter --no-host --width would be the minimum required information for us to be able to help you. (Personally Identifiable Information like serial numbers and MAC addresses will be filtered out by the above command)
    Also, please copy-paste that output in-between 3 backticks ``` at the beginning and end of the code/text.
