Thank you for your answer. As it happens, the bug stopped some time after I reloaded the grub files a few weeks ago. Since then a number of patches have been edited which may have also corrected the problem. I really don't know what happened but now I can enjoy Ubuntu without fearing a crash.
I had no temperature problems. you can close the case.
