How much RAM does it have?
You should check inside and yank one of the memory modules if that is possible and there are two inside.
Before that, did you check the md5sum of the downloaded ISO?
Freezing that often can be caused by:
-failing memory modules or memory controller (new PC so just check the memory)
-errors while downloading the ISO
-failing USB boot device used for installing
-overheating processor/graphic card.

Thanks,
Only one stick of 4GB.
I didn't check the MD5 sum. Time I looked up how to do this.
If it is over heating, it is happening within about a minute of booting.

I did the check sum on the ISO, and its HAS was correct, so that isn't it.

I did the check sum on the ISO, and its hashfile was correct, so that isn't it.

Here are the current bios settings...









Any suggestions of changes appreciated.
It did run for longer befoer locking up today. About 3 minutes, so maybe there is a heat problem. That would suck. I was doing a latency test, and it was giveing about 64000ns on the servo thread and 55000ns on the base thread. Also not great.

The latency is fine for this kind of PC and the mesa card will be happy as. This sounds very familiar to what I experienced with a couple of J1850's.

I would suggest you uninstall thermald

There are reports of similar lockups on the N3150., See arstechnica.com/civis/viewtopic.php?f=16&t=1322553

Thanks Rod, I tried sudo apt-get remove thermald, but it reports that "thermald is not installed".

I wonder if it should be installed then?
Uninstalling it did not recover my 2 machines.

I wandered off after trying that uninstall, leaving the thing running with only the terminal window open. After a half hour it nad not locked up yet. Then I started a latency check, and opened a couple of youtube windows, causeing it to freeze after about a minute.

I would disable EIST and Turbo mode.

The lockups may be Intel video related, you might try adding
intel_idle.max_cstate=1 to the kernel command line (with grub)
