(Note: this is not mythbuntu exactly, but the garden variety Ubuntu 12.02 with Gnome fall back (or whatever it was called -- not Unity). Normally I let the machine run 24/7. Over the past few days I've turned the TV on and found that the machine is hung. I get no response to the remote control, or the wireless USB keyboard. I tried connecting with ssh from another machine without success. The only thing that I've tried that works is to force a power down and then restart.

And while I had it open, I would take a close look at all the capacitors on the MoBo and add-on cards and see if any were leaking or bulging. If the caps look OK and the machine is clean and not running hot and still locking up, I might try swapping out the power supply.

FWIW, you shouldn't need to use sudo to run the sensors command. Also, if you have an NVidia GPU, you can check its temperature with the command:
DISPLAY=:0 nvidia-settings -q [gpu:0]/GPUCoreTemp
