Upgraded to 2.7.13 -- W T F --

I'd try reseating the RAM modules and running memtest. Could be a bad memory location that the 64 bit OS is accessing that the 32 bit OS doesn't touch.

if you don't already have a grub menu selection for memtest run
When you reboot there should be a grub menu item for memtest, select that, or if it is not in the main main it maybe hidden in the advance selection.

Will try that later today, now off to hospital for some X-ray of my hip and knee that are a bit problematic.

Later..

Code:

sudo apt-get install memtest86

Installed memtest86, new entries in grub but not one of these works! Freezes up at once only restart will work.

I think I have to get another PC as this is just too much, looking at

No eBay APP ID and/or Cert ID defined in Kunena configurationLooks like you got a bit of a lemon, was it brand new or second hand ?

I went with one of these, it's going in a cabinet with all the bits & pieces, probably not a solution for you.

And one of these SSD's. The vendor sent me a 16GB module even tho I ordered an 8GB


Might even consider one of those 12v mini supplies.

I did install memtest on USB and it boots and is running memtest86+ test right now, about ½ way and no errors so far.

Also I noticed that after remove irqbalance the latency values got a bit worse.
So many variables that can go wrong.

New used

Sorry but loose parts gets more expensive than a BRIX or a NUC and those small boxes are neat as I have lack of space
If I had the money I would buy a better PC but on my pension it is not going to happen just now.
